export 'render' (imported as 'render') was not found in 'mustache' (possible exports: default)

[cre8]

I got the error when using it in a library in my angular application.

Error appeared in version 4.2.0, but not after downgrading to 4.1.0

Could you share how you're downloading & using mustache.js? Any building involved or downloading directly from a CDN?

E.g. I would not expect the same to happen if you used the simplest alternative from the README:

https://unpkg.com/mustache@latest

[cre8]

I used it via npm without any more configuration like in the angular.json file.

A dif between the two versions should give more insights, will do it the next days and report the findings.

I have the same problem with a Angular 12 nx monorepo.
I've installed via npm install mustache@latest --save-exact and npm install @types/mustache@latest --save-exact.
I'am upgrading from Version 3.1.0 to 4.2.0 and now i'am getting lots of

Error: export 'render' (imported as 'render') was not found in 'mustache' (possible exports: default)

Our imports looks like:

import * as mustache from 'mustache';

A downgrade to 4.1.0 works fine. So i have to stay there for now.

Push: Error is still relevant. Can't upgrade mustache to Version 4.2.0 in the Angular 14 and NX Upgrade process.

Probably same root cause as #786 ?

Import it like import mustache from 'mustache'. And use as mustache.render

[JohnnyDevNull]

Import it like import mustache from 'mustache'. And use as mustache.render

import mustache from 'mustache'; leads to TS1192: Module '".../node_modules/@types/mustache/index"' has no default export.

And enabling esModuleInterop with over 200 libraries in our monorepo is no option. That leads to other problems. So actually it's impossible to update.

Push, still relevant... unable to update. Dependabot PR is still blocked.

Downgrade to 4.1.0 works for now 👎

[JohnnyDevNull]

Still broken, staying at 4.1.0

I make a new TypeScript rewrite fork for it. However, it still lacks test cases and is incompatible with some APIs. If anyone is interested in it, please feel free to contribute it.

Try this,

1. Remove/Delete node_modules directory & package-lock.json file from project.
2. Remove mustache from 'dependencies' of package.json file. If its present in 'devDependencies', then remove it from there as well.
3. Install npm mustache again using 'npm i mustache --save'.

I was facing the same same issue today, resolved using these steps.
