下载一个vue项目执行npm install 后运行项目npm run dev后出错 - 问题解决

时间：2021-01-04 22:54:59

在SVN上拉下来一个vue项目，上面没有提交项目里面的node_modules文件夹，所以要自己执行 npm install 安装，但安装完后运行项目后却报错了：

$ npm run dev

> poverty@1.0.0 dev F:\05 poverty alleviation project\poverty-git

> webpack-dev-server --inline --progress --config build/webpack.dev.conf.js

。。。。。此处省略加载的进度。。。。。

考虑是没有把需要的插件或者包都安装下来，所以就重新执行了一次 npm install ，然后根据报错信息，重新安装ajv（没见过这玩意，这个是什么呢？）

$ npm install

npm WARN ajv-keywords@3.2.0 requires a peer of ajv@^6.0.0 but none is installed. You must install peer dependencies yourself.

$ npm install ajv@^6.0.0

+ ajv@6.5.2

  run `npm audit fix` to fix them, or `npm audit` for details

然后下一步重新执行 npm run dev 就可以运行代码了。
