Webpacker: webpack binstubs not found, but present?

[Eearslya]

Just started out with a brand new rails 5.1.4 project on Windows, using --webpack=react. During the rails new task, the rails webpacker:install:react threw out an error.

webpack binstubs not found.
Have you run rails webpacker:install ?
Make sure the bin directory or binstubs are not included in .gitignore
Exiting!

The binstubs webpack and webpack-dev-server are both in the bin directory and marked as executable. I'm not sure why it thinks the binstubs are missing.The binstub works just fine if I run it myself.

Here's all the information/steps I tried to take for reference. I've also tried bundle binstubs webpacker --force as the log suggests below.

I found the issue. 202d0a5b3132bddb292306e57b1ae785f5697f29 is the commit that fixed this, but it hasn't been rolled into a release as of yet.

Temporary solution is to run the gem off of the git repo.
gem 'webpacker', git: 'https://github.com/rails/webpacker.git'
Here's hoping it gets a bugfix release soon!

Will make a new release this weekend 👍
