'npm update' 可以使用全局包吗？

Question

If I have a Node.js package with a missing node_modules folder. Executing the npm update command will create and properly populate the node_modules folder with all the necessary packages.

What I don't understand is;

1. Why does it include packages which are already present in the global node_modules folder?

2. Why will it not create folder links instead?

3. Am I missing a command line parameter?

Thanks!

Edit :

1. Running the npm update -g command will not solve the problem.

2. I don't know if it is relevant information, but I'd like to solve it in Windows OS.

Answer 1

Global and local packages are treated differently (rightly so.).

npm update -g will update all global packages

This is documented here .
