node.js - NPM:在具有nvm的Windows 10上运行npm -v时找不到npm-cli.js

Question

我在Windows 10上使用nvm，因此我安装了 Node 10.19.0:

nvm install 10.19.0

nvm use 10.19.0

node -v

v10.19.0

npm -v

internal/modules/cjs/loader.js:638
    throw err;
    ^

Error: Cannot find module 'C:\Program Files\nodejs\node_modules\npm\bin\npm-cli.js'

PS C:\workspace\my-front>

我看到了C:\Program Files\nodejs\node_modules 文件夹，它是空的。
如何重新安装我的node + npm安装？
我尝试这样做，但无法解决我的安装问题:

PS C:\workspace\my-front> nvm uninstall 10.16.0
Uninstalling node v10.16.0... done
PS C:\workspace\my-front> nvm list

    8.9.2
PS C:\workspace\my-front> nvm install 10.19.0
Downloading node.js version 10.19.0 (64-bit)...
Complete
Creating C:\Users\foo\AppData\Roaming\nvm\temp

Downloading npm version 6.13.4... Complete
Installing npm v6.13.4...

Installation complete. If you want to use this version, type

nvm use 10.19.0
PS C:\workspace\my-front> nvm use 10.19.0
Now using node v10.19.0 (64-bit)
PS C:\workspace\my-front> node -v
v10.19.0

C:\workspace\my-front> npm -v
internal/modules/cjs/loader.js:638 ...

Answer 1

mcAfee阻止node_modules目录的下载。

解决方法:

转到https://nodejs.org/dist/latest-v10.x/并下载zip文件

打开zip文件并在node_module\npm中复制C:\Users\foo\AppData\Roaming\nvm\v10.19.0\node_modules\npm

npm -v

6.13.4
