How to clear cache in Yarn?

Question

I am doing some benchmark tests for Facebook's Yarn. For this, I need to clear my global Yarn cache.

Is there a command available for this? I have force-removed my ~/.yarn-cache folder, but this seems to be quite manual.

Ok I found out the answer myself. Much like npm cache clean, Yarn also has its own

yarn cache clean

In case others miss this, be certain to run this from the user account running yarn. In my case, I was trying to clean a continuous integration server with a different Windows account than the one our project builds on, and it wasn't removing files until I realized I needed to run it from that account. – daniel.caspers Jun 03 '19 at 15:33

Run yarn cache clean.

Run yarn help cache in your bash, and you will see:

Usage: yarn cache [ls|clean] [flags]

Options: -h, --help output usage information -V, --version output the version number --offline
--prefer-offline
--strict-semver
--json
--global-folder [path]
--modules-folder [path] rather than installing modules into the node_modules folder relative to the cwd, output them here
--packages-root [path] rather than storing modules into a global packages root, store them here
--mutex [type][:specifier] use a mutex to ensure only one yarn instance is executing

Visit http://yarnpkg.com/en/docs/cli/cache for documentation about this command.

@LeoCaseiro this is what could be called "race conditions" XD – Marco Ottina Dec 19 '20 at 11:41

@EliavLouski `yarn cache clean package-name` see documentation for details: https://classic.yarnpkg.com/en/docs/cli/cache#toc-yarn-cache-clean (it's missing in the documentation of Yarn 2 though, but hopefully, it's still supported). – pmrotule Oct 29 '21 at 14:26

Also note that the cached directory is located in ~/.yarn-cache/:

yarn cache clean: cleans that directory

yarn cache list: shows the list of cached dependencies

yarn cache dir: prints out the path of your cached directory

its not always in `~/.yarn-cache/` – Pants Jan 03 '20 at 16:10

On my Mac the cache directory is `~/Library/Caches/Yarn/v6` as reported by the `yarn cache dir` command. – pamcevoy Feb 20 '20 at 16:26
I have both. `yarn cache dir` returns `~/Library/Caches/Yarn/v6`. But `~/.yarn-cache/` is 2.8GB and hasn't been updated since January 2018. `yarn cache clean` _**does not work**_ on `~/.yarn-cache/`. It has to be manually deleted. Cache location seems to be a tumultuous subject https://github.com/yarnpkg/yarn/search?q=.yarn-cache&type=Commits – mccallofthewild May 06 '20 at 02:54
On my Mac (M1), I found some yarn global modules sitting at `~/.config/yarn/global/node_modules` as well. – Saifur Rahman Mohsin Dec 13 '22 at 06:47

In addition to the answer, $ yarn cache clean removes all libraries from cache. If you want to remove a specific lib's cache run $ yarn cache dir to get the right yarn cache directory path for your OS, then $ cd to that directory and remove the folder with the name + version of the lib you want to cleanup.

To clear the cache, run the following command:

yarn cache clean → This command will clear the entire Yarn cache for you
To clear the cache selectively:

yarn cache clean packagename → for example: yarn cache clean react

To list out the cache for all the packages currently cached, run the command below:

yarn cache list → From here, you can choose to selectively remove packages.
