问题
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?
回答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
回答2:
This error may also occur if you are working in a directory which was deleted from some other terminal instance.
回答3:
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 [...].
回答4:
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.
