v3.0.0 with Node v12/NPM 6.9.0 gives "TypeError: fsevents is not a constructor"

[sekoyo]

Is this a bug report?

Yes

Did you try recovering your dependencies?

Yes, tried clean install use Node v12 and NPM 6.9.0

Which terms did you search for in User Guide?

Anything about fsevents errors.

Environment

System:
OS: macOS 10.14.4
CPU: x64 Intel(R) Core(TM) i7-4960HQ CPU @ 2.60GHz
Binaries:
Node: 12.0.0 - /usr/local/bin/node
Yarn: 1.15.2 - ~/.npm-global/bin/yarn
npm: 6.9.0 - ~/.npm-global/bin/npm
Browsers:
Chrome: 73.0.3683.103
Safari: 12.1
npmPackages:
react: ^16.8.6 => 16.8.6
react-dom: ^16.8.6 => 16.8.6
react-scripts: 3.0.0 => 3.0.0
npmGlobalPackages:
create-react-app: 2.1.8

Don't know why it says create-react-app: 2.1.8, if I do npm show create-react-app version it echos 3.0.0.

Steps to Reproduce

Install with NPM 6.9.0

Expected Behavior

npm start starts the server

Actual Behavior

fsevents throws:

/Users/.../node_modules/chokidar/lib/fsevents-handler.js:28
  return (new fsevents(path)).on('fsevent', callback).start();
          ^

TypeError: fsevents is not a constructor

    at LOOP (fs.js:1622:14)
    at processTicksAndRejections (internal/process/task_queues.js:81:9)

Because even though chockidar depends on fsevents 1.2.8, it doesn't get installed, possibly due to chockidar declaring it as an optional dependency: https://github.com/paulmillr/chokidar/blob/master/package.json#L24

Instead fsevents v2 gets installed which has a different API which exports a plain object (new keyword breaks on it).

⚠️ Works using yarn. (and older NPM versions as it worked on Node v11 I was using yesterday)

Reproducible Demo

Do create-create-app using NPM 6.9.0 and try to run it.

[ghost]

I had the same issue. How did you solve it?

[fsepulveda]

Same issue...
TypeError: fsevents is not a constructor

node: v12.0.0
npm: 6.9.0
create-react-app: 3.0.0

[ghost]

I had the same issue. How did you solve it?

Updated 22:30
This worked for me:

1. I deleted my react app because I realized I did not have yarn installed.
2. So I installed yarn.
3. Then, again I did npx create-react-app my-app, and it worked. The issue disappeared.

Other things I did:

• Installed node globally
• Cleared the node caché

[sekoyo]

For now you can downgrade Node, or remove node_modules and package-lock.json and do yarn install instead. Author of chokidar package said it will be fixed in upcoming v3.

[nathan-charrois]

This issue is very common.

See #6657 (reported by me), #2558, #3588, #4308.

Unfortunately all these threads lead to dead-ends. I've reproduced this error on a fresh, brand new iMac and on my Windows PC. For some reason it's never drawn any attention.

[joshunger]

It looks like Node.js v12 removed v8::Handle which fsevents@1.2.8 uses. See https://electronjs.org/blog/nodejs-native-addons-and-electron-5.

You can reproduce:

nvm use 12
yarn init
yarn add fsevents@1.2.8

Output:

  SOLINK_MODULE(target) Release/.node
  CXX(target) Release/obj.target/fse/fsevents.o
../fsevents.cc:43:32: error: no template named 'Handle' in namespace 'v8'
    static void Initialize(v8::Handle<v8::Object> exports);

[sam-github]

Fix in fsevents/fsevents#271, waiting on nodejs/nan#849

[amitpatil321]

Giving up npm and using yarn helped me.
I removed node_modules package.lock yarn.lock and then cleared npm cache with --force.

and then yarn install and yarn run...and its working!

[ls-jonathan-jouret]

FYI:

For me, removing node_module and yarn.lock then running yarn fixed the issue

[galohernandez]

I solved installing yarn and then sudo forever npm and node_modules. Try this https://timonweb.com/posts/install-npm-packages-without-sudo/ for permission issues. After that I created a new project and finally i go the dev server on

This worked for me so well that I would recommend to any one in my situation, this morning.
what happen to me: I've cloned react app() from github to local machine with:

• macosx (10.12.6)
• Node v10.15.3 and NPM v6.9.0
• and then I tried to "npm intall" to get down all dependencies as usual, and then I've tried to run the devServer by running the command: " npm start " to my surprice, npm quited with error above.
  For me 'destroying' the whole react app was not an option, so I have just removed the node_modules folder and also deleted the package-lock.json, as suggested by DominicTobias and then installed yarn globally by using the MacPorts utility
  After installing yarn, I've cd to the react app project on the local machine, and then executed the command: "yarn run start" And voilà! everything starting running as expected.
  many thanks to DominicTobias

[Shahor]

"resolutions": {
    "fsevents": "
}

Resolved the issue temporarily by adding this to my package.json.

Until chokidar releases their next version, the api is fully compatible with latest version so it should work just fine 👍

[yairEO]

@Shahor - Did as suggested but still not working :/

[fr0zenK]

all my problems i've got is from fsevents
why so terrible :(

[alan345]

rm -rf node_modules
rm -f yarn.lock 
yarn

Solve the issue

[majda]

Downgrading node version solves the issue.

Please note that I have uninstalled all versions of the Node on my machine (and yarn as well), and then, instead of installing Node manually, installed nvm. This allows you to switch between different versions of Node easily.

Once nvm is installed run nvm install node to install the specific version (I have installed 10.15.3)

To change Node version run nvm use <version>

Check you're set up correctly by running node -v

[udhayakumaran]

Giving up npm and using yarn helped me.
I removed node_modules package.lock cleared npm cache with --force.

and then yarn install and yarn run...and its working!

This solution from @amitpatil321 worked for me. 👍

[klimsava]

very good way, thanks @majda

[paigen11]

Same issue using node v11.10.0 and npm v6.9.0, my issue was solved as well by deleting the yarn.lock and node_modules and running yarn again. I hope this gets fixed soon - it's very annoying to do a fresh install and have it break immediately when I try to launch the app

[diegodesouza]

@dominictobias What version of node works for you? I have tried several and yet no luck

[sekoyo]

@dominictobias What version of node works for you? I have tried several and yet no luck

The LTS version works (10.6.0), I have 10.5.3

[matthewstitt42959]

I was recently able to resolve this issue by going into the Node_module folder and finding fsevents folder. I changed the name of the folder to fsevent_old. I was then able to run React without an issue.

[mattrafalko]

I was able to resolve the issue with npm i -S fsevents.
I did not have any luck with @Shahor 's fix, and I didn't try any solutions involving yarn as I don't use yarn.

[vjpr]

So chokidar@2 seems broken as pointed out in this comment.

We should use chokidar@3.

From OP's stack trace we can't see which package uses chokidar because its run async from a callback.

Go to the earliest line we have in the stack trace, and place a console.trace() outside the callback. For me it was fsevents-handler.js:333. This let me see that it was watchpack that depended on chokidar@2.

When using pnpm in a monorepo...

In a pnpm monorepo we can search for usages like so: pnpm ls --depth=100 --filter my-package chokidar, which also showed me:

└─┬ react-scripts@3.0.1
  ├─┬ react-dev-utils@9.0.1
  │ └─┬ fork-ts-checker-webpack-plugin@1.1.1
  │   └── chokidar@2.1.6
  ├─┬ webpack@4.29.6_webpack@4.29.6
  │ └─┬ watchpack@1.6.0
  │   └── chokidar@3.0.1
  └─┬ webpack-dev-server@3.2.1_webpack@4.29.6
    └── chokidar@3.0.1

Using pnpm and pnpmfile.js it can be patched like so:

if (pkg.name === 'watchpack') {
  pkg.dependencies['chokidar'] = '3.0.1'
}
// and webpack-dev-server and fork-ts...

Then trigger a reinstall like so:

pnpm up --depth=100 --filter my-package

This fixed it for me.

[frknasir]

I was able to resolve the issue with npm i -S fsevents.
I did not have any luck with @Shahor 's fix, and I didn't try any solutions involving yarn as I don't use yarn.

Yes, Its work but unfortunately we did not found the actual error to resolve that permanently.

[rathnak]

It may seem weird, but I was able to get it working after running:
$sudo npm install npm@latest -g

[Parthan-Akon]

I also had the same issue though am using MacOS the issue is kind of bug. I solved this issue by repeatedly running the commands,

• sudo npm cache clean --force
• sudo npm uninstall
• sudo npm install

One time it did not worked but when I repeatedly cleaned the cache and after uninstalling npm, reinstalled npm, the error went off. Am using Angular 8 and this issue is common

[ronanmockett]

I had the same problem because I created new project using sudo what caused permission conflict.
$ sudo npx create-react-app my-app // Did not work

$ npx create-react-app my-app
$ cd my-app && npm start // Work like a charm`

I hope this help someone to resolve this issue.

Thank you this worked for me!

[mvermadev]

Hello Ronan, if you are using 'npx' to create react app then you didn't need to add sudo command at the beginning. If you are using 'npm' then you need (if system want super user permission) to add at the beginning. I hope you got it. Regards, MANISH VERMA.

You need to install the yarn before creating your app

sudo npm i -g yarn
npx create-react-app my-app
cd my-app
npm start

It have worked for me. ;)

Yes yarn is a good method to create react app.

If you want to use 'npx' then you must have npm 5.2+ version in your system.

I had this problem on macOS 10.13 too while using yarn, on a brand new create-react-app. I do not have a node version set in my package.json file, but for reference here is the rest of my package.json

{
  "name": "star-ratings-basic",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "react": "^16.9.0",
    "react-dom": "^16.9.0",

    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  }
}

this happened to me while using NVM (node version manager) and had these versions of node & npm active respectively

$ npm -v
node 6.10.2
$ node -v
v12.8.0

deleting my yarn.lock file & deleting the node_modules folder and then running yarn worked immediately.

interestingly, I was able to get a diff on the regenerated yarn lock file compared to the old one. as seen by git diff ( note minus and plus symbols )

I'm using nvm, and I have node 12.8.0 activated. should I do something else to update npm or node in my system? I'm not sure I understand if there's any steps I'm missing when you say "First update your nodejs in your system". am I not using the latest versions?

[jasonfb]

it appears to do this for me on every create-react-app I make

[mvermadev]

I also faced that situation in my system, so I researched alot about it then I got that, first Clean your yarn then I Cleaned my apt using 'sudo apt clean' then 'sudo apt update' for repair and updating packages then 'sudo apt upgrade' for require upgrades to my packages. Then create a new react app. It might be work in your system.

incidentally I am on mac OS 10.13.6 using Xcode 9.4.1 with gcc clang version clang-902.0.39.2

I wonder if there's a way to blow away my yarn binary to clear the problem?

some people on the reactiflux Discord channel are recommending downgrading to Node 11 until the issue is mitigated.

You need to install the yarn before creating your app

sudo npm i -g yarn
npx create-react-app my-app
cd my-app
npm start

It have worked for me. ;)

This indeed works. I struggle making my first react app to work at first, but eventually installing yarn (and use it after that) make it work, it really do the trick ✨

I no longer get this issue, tested with Node 12.7 and 12.9 using either NPM or Yarn. Thinking of closing this soon as it seems to have been resolved.

[barunprasad]

rm -rf node_modules
rm -f yarn.lock 
yarn

Solve the issue

This worked for me. I had Node version: 12.8.0 on a mac
