webpack Error: Cannot find module 'webpack-cli/bin/config-yargs'

电脑使用的webpack版本为3.12.0

局部安装webpack-dev-server，而且全局安装webpack-dev-server后，发现以下error

webpack-dev-server
The CLI moved into a separate package: webpack-cli
Please install 'webpack-cli' in addition to webpack itself to use the CLI
-> When using npm: npm i -D webpack-cli
-> When using yarn: yarn add -D webpack-cli
module.js:549
    throw err;
    ^

后，发现webpack3.x的版本与webpack-dev-server3.x不兼容

卸载局部和全局webpack-dev-server

npm uninstall -g webpack-dev-server

 npm uninstall --save-dev webpack-dev-server

 

 

安装指定版本的webpack-dev-server2.9.7

npm install webpack-dev-server@2.9.7 --save-dev

-bash: /usr/local/bin/webpack-dev-server: No such file or directory

全局安装webpack-dev-server2.9.7

npm install webpack-dev-server@2.9.7 -g

后能够实现热加载。
