项目开发到一半，使用cnpm run dev，总是报错：Error: Cannot find module ‘XXX’

Question

项目开发到一半左右，重新运行了一下cnpm run dev ，然后总是报错说Cannot find module‘ XXX1’，使用cnpm install ‘XXX’ 在项目中插入该模块，然后再运行cnpm run dev，又接着报不能发现另一个模块Cannot find module‘ XXX2’，如此一直报错。。。求大神们解决一下，谢谢

命令行报错如下：

D:\demo111>cnpm run dev

> demo111@1.0.0 dev D:\demo111
> webpack-dev-server --inline --progress --config build/webpack.dev.conf.js

删除项目目录下的 node_modules 目录，Linux下用root账户重新 npm install 或者 淘宝镜像 cnpm install ，Windows下用管理员权限运行terminal运行 npm install 或者 淘宝镜像 cnpm install。

Answer 2

删除node_modules和package-lock.json 重新install试试

Answer 3

删除node_modules

npm 或是cnpm换着试试，有时候某一个会缺少东西
