Would have removed .. in heroku deploy log

Question

a few days ago I started to see

 Would have removed best_in_place (2.0.2)
 Would have removed thor (0.16.0)

in my heroku deploy output.

Answer 1

That's a bug in Heroku deployment configuration. It writes a file .bundle/config which has a line:

BUNDLE_DRY_RUN: false

When bundler loads this global config file, it translates this to :dry_run => "false" When it checks for this setting, it's checking settings[:dry_run], which is a string, which evaluates to true.

You can remove this line by some shell commands (heroku run bash):

mv -f .bundle/config .bundle/config.orig
sed '/BUNDLE_DRY_RUN/d' < .bundle/config.orig > .bundle/config

And then run

bundle clean
