Rails generate error: No such file or directory - getcwd

Question

When running rails generate on a new Rails 4.2 project, I keep getting the error:

~/.rbenv/versions/2.2.0/lib/ruby/gems/2.2.0/gems/spring-1.3.0/lib/spring/configuration.rb:37:in `pwd': No such file or directory - getcwd (Errno::ENOENT)

How can I fix this?

Answer 1

The error is caused by an existing Rails Spring process running in the background.

You can easily solve this by running ps ax | grep spring to find the process id and then kill it.

There's an issue on the Rails GitHub about this: https://github.com/rails/spring/issues/247

Answer 2

This error may also occur if you are working in a directory which was deleted from some other terminal instance.

Answer 3

On my machine the same problem was arising because spring server stopped responding.

1:- To restart the spring server type in terminal

$: spring restart

2:- Try running the generator again.

Answer 4

If the directory (or some sub directory Rails will work with) you are working was renamed or removed, you'll have to run

cd .

and then you can run rails generate [...].
