Rails precompile trying to reference tmp file

Question

I'm trying to precompile my assets and Rails keeps throwing an error about missing a .lock file in the tmp directory:

rake aborted!
No such file or directory - /.../My-App/tmp/cache/assets/sprockets%2Ffa8030279a511d669a1c26925f5bb97520130214-20129-dtn8tg.lock

The error shows up when I add the line

config.assets.initialize_on_precompile = false

to my application.rb file, as per the instructions on Heroku. I've tried running rake assets:clean, which seems to run fine but doesn't solve the problem.

Any idea why it's referencing a .lock file in the tmp directory?

Answer 1

After much change, I just decided to close textmate and delete the tmp folder. After that, everything works as expected...

Answer 2

For the tmp and .lock it's by design of the file_store.

As suggested here, check the in-memory implementation.

Can you try config.assets.cache_store = :memory. If that works, its a bug with Rails' FileStore.

Are you on windows ? Probably the path /.../ is too long ?
