npm install 还是报错比如xxx不在某个依赖包

1.pull下来最新代码
2.切换到dev开发分支
3.npm install 安装依赖包
4.npm run dev
报错，比如‘xxx’ was not found in 'xxxxpackage’

一般由于版本问题，在package中
“dependencies”: {
“axios”: “^0.17.1”,
“babel-polyfill”: “^6.23.0”,
“cross-env”: “^5.0.0”,
“element-ui”: “^2.8.2”,
“font-awesome”: “^4.7.0”,
“font-awesome.css”: “^4.7.2”,
“jquery”: “^3.4.1”,
“js-cookie”: “^2.2.0”,
“moment”: “^2.23.0”,
“npm”: “^3.10.10”,
…
}
这里一般都是安装最新版本，但有些不能向下兼容，有些依赖包需要回退版本
