@JorgeDDW is right, I reproduced the issue

[gorborukov]

As a temporary solution you can create and fill webpacker.yml manually and run rails webpacker:install again.

But @JorgeDDW is trying to rails new; not webpacker:install?

As you say.. rails new

So, I tried and get something weird

...
Using webpacker 4.0.7 from https://github.com/rails/webpacker.git (at master@2cef2fd)
Bundle complete! 17 Gemfile dependencies, 75 gems now installed.
Use `bundle info [gemname]` to see where a bundled gem is installed.

Bundler is installing for ruby but the dependency is only for x86-mingw32, x86-mswin32, x64-mingw32, java. To add those platforms to the bundle, run `bundle lock --add-platform x86-mingw32 x86-mswin32 x64-mingw32 java`.

Yes, it must be running after project creation

1. Initially run rails new ... — skip errors, anyway, the project already will be created.
2. Create config/webpacker.yml manually
3. Fill it with contents (for example)
4. Change directory to project root
5. Run rails webpacker:install, decline our existing webpacker.yml overwrite

rails/webpacker#2301 is a proposed fix for this issue.

[vvo]

Small info from a rails newcomer: on Friday 8th 2019 the default rails new blog from the rails getting started was working. Today Tuesday 12th 2019 the default rails new blog is no more working. Should we update the getting started guide with the temporary solution so that new users right now are not bitten by this bug?

PS: I use the standard rails command, not edge, just the default rails command of 6.0.1 (current stable).

[eugeneius]

Webpacker 4.1.0 was released two hours ago, which is why this error now happens even without the --edge option. Downgrading to 4.0.7 makes webpacker:install work again.

@gouravtiwari 👋 rails new is broken - would you mind taking a look at rails/webpacker#2301?

[ytbryan]

cc @gauravtiwari

[gauravtiwari]

Thanks for raising the issue, it seems to have worked when I tested locally after release but I can reproduce now. Will look into it.

[gauravtiwari]

@eugenebolshakov @ytbryan Could you please check this pr? rails/webpacker#2366

[eugeneius]

I can confirm that using that branch resolves the issue:

gem 'webpacker', git: 'https://github.com/rails/webpacker', branch: 'fix-path-issue'

👍

[gauravtiwari]

Released 4.2.0

[eugeneius]

Thanks for the quick fix @gauravtiwari ❤️

Closing as both rails new and rails new --edge now work correctly 🎉

[olivierlacan]

This same webpacker errors occurs under Rails 6.0.2.1 and webpacker 4.2.2 with a brand new rails new (no arguments other than the app name) generated application anytime bin/rails is called (even without arguments):

rails command stacktrace

$ bin/rails
The most common rails commands are:
 generate     Generate new code (short-cut alias: "g")
 console      Start the Rails console (short-cut alias: "c")
 server       Start the Rails server (short-cut alias: "s")
 test         Run tests except system tests (short-cut alias: "t")
 test:system  Run system tests
 dbconsole    Start a console for the database specified in config/database.yml
              (short-cut alias: "db")
new          Create a new Rails application. "rails new my_app" creates a

new application called MyApp in "./my_app"
All commands can be run with -h (or --help) for more information.

In addition to those commands, there are:

To be fair, I'm experimenting with a weird setup in which I'm using the macOS system Ruby (hence /System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/lib/ruby/2.6.0 in the trace) and I've setup bundler to install to vendor/bundle. Here's the repro app as-is although it's a stock Rails 6.0.2.1 app aside from the specific bundle install --path vendor/bundle instruction.
