在 Rails 上冻结时无法写入锁定文件 Ruby

Question

Hello I'm trying to run the following commands to prep my Rails app for production:

bundle lock --add-platform ruby

bundle lock --add-platform x86_64-linux

Then I get this error:

Cannot write a changed lockfile while frozen.

What is going on here? What is the lockfile for? What does it mean to be frozen?

Answer 1

Running the following command allowed me to write to my lock file

bundle config unset deployment   

Answer 2

What is the lockfile for?

The presence of a Gemfile.lock in a.. repository ensures that a fresh checkout of the repository uses the exact same set of dependencies every time. https://bundler.io/v2.2/guides/faq.html

What does it mean to be frozen?

--frozen Do not allow the Gemfile.lock to be updated after this install. Exits non-zero if there are going to be changes to the Gemfile.lock. https://bundler.io/v2.2/man/bundle-install.1.html

This probably doesn't apply to you yet, but in Bundler 3, --deployment will imply --frozen .

Answer 3

thats because you are in production and you dont want any changes to you Gemfile.lock file in deployment, so you freeze it, to unfreeze it run:

bundle config unset frozen
