Incorrect integrity when fetching from the cache - yarnpkg

When running yarn add --dev jest, I got error Incorrect integrity when fetching from the cache.
Full output:
tests (master)$ yarn add --dev jest
yarn add v1.19.0
info No lockfile found.

error Incorrect integrity when fetching from the cache

I tried removed node_modules, re-ran yarn install and yarn add --dev jest to no avail.
How do I fix this?

yarn cache clean
To fix this, run:
yarn cache clean
yarn add --dev jest
From the yarn cache documentation:
yarn cache clean [<module_name...>]
Running this command will clear the global cache. It will be populated again the next time yarn or yarn install is run. Additionally, you can specify one or more packages that you want to clean.
You can also see where the cache is with yarn cache dir.
yarn cache dir
Running yarn cache dir will print out the path where yarn’s global cache is currently stored.

Yarn cache clean did not help. We must downgrading yarn version on the server.
It turns out that the problem is associated with the use of private packages.
GitHub Yarnpkg - "Incorrect integrity when fetching from the cache" #7584

For anyone who is working with heroku and sees this error:
install heroku cli
login via heroku login
heroku plugins:install heroku-repo
heroku repo:purge_cache -a $YOURAPPNAME
then do a manual rebuild

Clean the cache and reinstall:
yarn cache clean
yarn install -f

You need to run these two commands before installing the package:
yarn config set unsafe-disable-integrity-migration false
yarn cache clean

Tried to upgrade yarn and it solved my problem. It may be due to the compatibility issue
yarn policies set-version
Will download the latest stable release

Installation of private npm package from CodeArtifact fails with "401 Unauthorized" with yarn and yarn.lock

We have a private npm package in CodeArtifact that we want to install as part of our package.json.
We are using Yarn as a package manager and have a yarn.lock file to control the versions.
When trying to install with yarn install --frozen-lockfile it's failing on the installation of the private package with Request failed \"401 Unauthorized\.
When using npm it's working fine. But we want to stick with yarn.
Anybody experienced the same issue?

terminal defaults to old yarn version (lerna bootstrap)

I don't think this is an issue specific to lerna, I actually think it is nvm related (though I commented out nvm from my .bash_profile to test that, without success).
I'm trying to lerna bootstrap but it keeps using (and failing) an older version (1.3.2) of yarn than what I'm running:
$ yarn -v
1.22.4
$ lerna bootstrap
info cli using local version of lerna
lerna notice cli v3.22.1
lerna info versioning independent
lerna info bootstrap root only
yarn install v1.3.2
error An unexpected error occurred: "patterns.map is not a function".
info If you think this is a bug, please open a bug report with the information provided in "yarn-error.log".

lerna ERR! yarn install --mutex network:42424 --non-interactive exited 1 in 'root'
lerna ERR! yarn install --mutex network:42424 --non-interactive exited 1 in 'root'
$ yarn -v
1.22.4
For me, this was happening in Ubuntu 20.04, and it solved with unistalling cmdtest:
sudo apt-get purge cmdtest
I rooted around in my filesystem and removed ~/.yarn and ~/node_modules/yarn and everything works now.
Upgrade yarn. I use brew so I used brew install yarn and it worked.

Failure of yarn upgrade

When I want to upgrade a dependency of my project (lodash package), I run the following command:
yarn upgrade lodash
I face with the following error:
yarn upgrade v1.12.3
[1/4] Resolving packages...
[2/4] Fetching packages...
error https://registry.yarnpkg.com/path-postId/-/path-postId-2.0.1.tgz: Extracting tar content of undefined failed, the file appears to be corrupt: "Unexpected end of data"
I consulted the mentioned page but I couldn't find any useful information to resolve the issue.
The following steps resolved the problem:
Remove the yarn.lock file.
rm yarn.lock
Recreate the yarn.lock file by running the following command:
yarn install
Upgrade the dependency using --skip-integrity-check:
yarn upgrade --skip-integrity-check lodash

replace yarn version v1.0.0 to v0.28.4

I currently used nightly builds to update my yarn and I'm using yarn v1.0.0-20170906.0822.
But it had a serious problem which is blocking deployment on Heroku.
So, I searched a way to migrate from v1.0.0xx to v0.28.4.
I tried to remove it using brew uninstall yarn however it failed to delete yarn so I can still v1.0.0xx shown when I hit yarn --version on the terminal.
I remember I installed yarn via brew, not npm.
Are there any other options to delete yarn and replace it with v0.28.4?
You can use the switch subcommand:
brew switch yarn 0.28.4
