'rails generate' commands hang when trying to create a model

Question

I\'m new to rails and decided this morning to dump my whole database design/model and start over. And being a noob, I\'m sure did it incorrectly.

I removed all the files

Answer 1

If your rails generate commands hangs, it is most likely that the generated binstubs of rails are the issue. As you mentioned, you renamed the project.

My educated guess is that some paths in the binstubs were still set to the old project directory but did not exist any longer.

There is a great article on how binstubs work here: https://github.com/sstephenson/rbenv/wiki/Understanding-binstubs

rails 4

To reset the binstubs, just delete your bin/ directory in rails and run:

# generates binstubs for ALL gems in the bundle
bundle install --binstubs

# ...OR, generate binstubs for a SINGLE gem (recommended)
bundle binstubs rake

rails 5/rails 6

To reset the binstubs, just delete your bin/ directory in rails and run:

rake app:update:bin

Why do we need to use the 'rake' command for rails 5 and higher, and not the 'rails' command itself?

Since rails 5 some 'rake' commands are encapsulated within the 'rails' command. However when one deletes 'bin/' directory one is also removeing the 'rails' command itself, thus one needs to go back to 'rake' for the reset since 'rails' is not available any longer but 'rake' still is.
