How to upgrade `pnpm`

#pnpm

I have summarized the procedure for upgrading the version of pnpm, which is a package manager for Node.

While updating the version of pnpm is not something you do frequently, when you do need to update it, you may wonder, "What should I do?" and it can take several minutes to several tens of minutes.

There are several installation routes for pnpm, and the method of version upgrade varies depending on which one you chose.

Here, I have only listed the procedures that I thought could be used generically (not limited to pnpm).
If you want to know other methods, please refer to the following GitHub Discussions.

In my case, the steps above allowed me to use pnpm without any issues. However, please be cautious as this method involves deleting the entire executable directory.

That's all!
