I'm running Linux Subsystem for Windows 10, I know I know you see Windows but it's kind of... Linux, and I installed Ruby by rbenv through this tutorial.

Answer 1

Even though the accepted answer solved your issue, I want to add another because I ran into the same error message but the underlying issue and my environment setup wasn't the same. However, recreating the executables in my app's bin folder did not solve the problem.

The issue: When I tried running bundle exec rails s or bundle exec rails c I got the same error as posted in the question. Using the apps executables worked fine though ./bin/rails s.

So the main differences from the question: I was using bundle exec when I got the error.

What was happening behind the scenes: bundle exec rails s was calling this executable /Users/robin/.rvm/gems/ruby-2.3.8/bin/rails which is shipped by the railties gem. I found this file was overwritten due to a gem which had an executable rails defined in its .gemspec.

What solved my problem:

Running $ bundle pristine railties (https://bundler.io/v2.0/man/bundle-pristine.1.html) so railties would be reset and with that the executable shipped by railties would overwrite the wrong one.

Addition: Of course it only helps as long as the intrusive gem shipping a rails executable is also updated and no longer wants it to be installed.

Answer 2

Try this command from your app folder:

rake rails:update:bin

Say y to replace the binaries.

I had the same problem using rails with Windows Linux Subsystem. I found the suggestion here:

Rails command Error

I tried it and it solved my problem, so maybe yours as well.
