今天遇到的问题：（这里只是个例子）

解决方法：

npm clean cache --force

删了node_modules 和 package-lock ，然后npm install

如果再不行，看看这个modulle所需要的npm啊什么鬼的版本是否符合你电脑的版本。

不符合就升级。

这里推荐一个最好的，最省心的方法：

首先打开Windows PowerShell 软件（以管理员打开），然后：执行下列所有命令去升级！

PS C:\\Windows\\system32> Set-ExecutionPolicy Unrestricted -Scope CurrentUser -Force
PS C:\\Windows\\system32> npm install -g npm-windows-upgrade
F:\\nodejs\\npm-windows-upgrade -> F:\\nodejs\\node_modules\\npm-windows-upgrade\\bin\\npm-windows-upgrade.js

added 72 packages in 14.766s
PS C:\\Windows\\system32> npm-windows-upgrade

Upgrading npm (fallback method)... 
You wanted to install npm 6.10.2, but the installed version is 6.9.0.

A common reason is an attempted "npm install npm" or "npm upgrade npm". As of today, the only solution is to completely uninstall and then reinstall Node.js. For a small tutorial, please see https://github.com/felixrieseberg/npm-windows-upgrade#usage.

Please consider reporting your trouble to https://aka.ms/npm-issues.
