[BUG] `npm update -g ds` removes all global packages and npm itself

[eAlexandrohin]

Is there an existing issue for this?

• I have searched the existing issues

This issue exists in the latest npm version

• I am using the latest npm

Current Behavior

Title. Basically self-destructs and purges all global packages and you can't even run npm after.
As I have tested, it works with any package that is not installed, even non-existent ones.

npm update -g [non-installed package]

To fix it, you need to re-install whole Node again with nvm.

Expected Behavior

Don't self-destruct and delete all global packages, when you specify package that is not installed.

Steps To Reproduce

1. run npm update -g ds
2. get the result

removed 203 packages in 641ms
The batch file cannot be found.

3. try to run npm again npm -v

'npm' is not recognized as an internal or external command,
operable program or batch file.

5. become aware of your unimportance to the universe

Environment

• npm: probably was 10.8.2, but I cannot check it because npm itself doesn't exist anymore.
• Node.js: 22.6.0 (64-bit) via nvm
• OS Name: Windows 10
• npm config: cannot give you, as stated above.

npm update should never be run with -g.

[eAlexandrohin]

npm update should never be run with -g.

but how you should update your global packages then?

[ljharb]

One at a time, manually, with npm install. (also you probably shouldn't have any global packages)

Here's the log I saw, hopefully it helps others find this issue:

PS C:...> npm i -g tsc
npm ERR! code EEXIST

PS C:...> npm update -g tsc

For me, fixing it required uninstalling nvm before reinstalling node the proper way (perhaps reinstalling node through nvm would work too).
