Close Failed in File Object Destructor

[Ben Batschelet]

I'm getting the following error when trying to use bass to run some nvm commands:

The command:

bass source $NVM_DIR/nvm.sh --no-use ';' nvm use --lts --delete-prefix

close failed in file object destructor:
sys.excepthook is missing
lost sys.stderr

Bass encountered an error!

What's weird is that some other (less useful) nvm commands are still working. If I do bass source $NVM_DIR/nvm.sh --no-use ';' nvm ls I get the expected output.

• fish --version
  • fish, version 2.4.0
• python --version
  • Python 2.7.12

Doing some quick and dirty debugging, it looks like the nvm use --lts --delete-prefix is taking too long to complete. Dumping out new_env on repeated calls is giving me incomplete output of varying length, so the parent process isn't receiving all of the output from the env_reader command and ultimately is getting malformed JSON.

This should be fixed. I am closing this. Please reopen if it is still broken.
