This should be a one liner as per the Yarn Docs.
It doesnot work always like that.
The problem
This happens if you have installed the latest version of Yarn. Then and only then one can change Yarn
versions. After installing the latest version of Yarn
, we can use the old version by setting Yarn to older version.
yarn set version classic
The classic
version is 1.x
version.
At this point we are good for our projects which use Yarn
version 1.x.
When we need to work on something which uses latest version of Yarn, then it should be just setting the Yarn version to latest.
yarn set version latest
Now Yarn
will not do the update. However, it shows the message as Why
it will not do that.
Warning: Your current Yarn binary is currently Yarn 1.22.15; to avoid potential breaking changes, ‘set version latest’ won’t receive upgrades past the 1.22.x branch. To upgrade to the latest versions, run yarn set version stable instead. Sorry for the inconvenience.
The solution
It is actually said in the Warning
.
yarn set version stable
Once this is done, Yarn can do latest
. From this point onwards the projects depending on latest version of Yarn will work.
But then sometimes yarn set version stable
also will not update the Yarn from classic
! This is not a big thing, but may come as a surprise! To fix this, we need to remove some files which are present at ~/
, that is at the UserHome folder. The files are
- package.json
- yarn-error.log
- .yarnrc
- .yarnrc.yml
Some files might be present, some might not be present. Just remove all the files which are available from this list. And then run the yarn set version
command.
This does the trick.
