javascript - npm install error, please ask for help

Question

When installing android sudio, npm install keeps reporting errors and the reason cannot be found.

Answer 1

If you use npm install to install dependencies, first you must have the package.json configuration file. If not, you need to add the dependent installation package name later if you want to install dependencies -g is the global installation --save is a local installation

Answer 2

It is okay to add the package name, that is to install a specified package. If you do not add the package name, it is also a legal command. If you are in a project folder and there is a package.json file, dependency packages will be installed based on this file.

So make sure you have package.json first
