After the node is installed in the NVM, the display is not internal or external when the NPM instruction is used

Problem replay

I reinstalled the computer system some time ago , Download again nvm To manage node edition , Maybe I didn't pay attention when downloading , Use today npm When you're in trouble npm Not internal or external instructions .

Think about Baidu , It's about environmental variables , I install nvm It was changed when D disc , I checked to see that it was automatically configured during installation , I haven't changed environment variables manually .

Input... At the terminal node -v enter , Alas, the magic thing is that it can show node Version number

Input npm -v It shows that it is not an internal or external command .

---

Then I uninstalled my original node edition , When I start again , Ah , I caught the culprit , Look at the picture below .

node The version is downloaded , Shows complete, But obviously download npm It's a mistake , I thought for the first time that I didn't give nvm The reason for setting the image address .

Solution

Run as administrator cmd, stay cmd Enter the following commands respectively in the window ：

nvm node_mirror https://npm.taobao.org/mirrors/node/
nvm npm_mirror https://npm.taobao.org/mirrors/npm/

Then you use it again nvm install node That's all right. . There is no error message .

You can check node Version and npm edition ：
