项目迁移: ‘webpack-dev-server‘ 不是内部或外部命令问题解决 和 eslint 配置记录

项目迁移

把个人笔记本上的 vue 项目,原封不动的挪到工作用的 pc 机上,原项目也是最近(半年内)写的。

迁移后启动项目

报错 'webpack-dev-server' 不是内部或外部命令,也不是可运行的程序。

解决办法
删除 node_modules

执行命令 npm install

最后运行 npm run dev

 

项目是不报错了,但是有 eslint 的错误提示。

想来可能是不同项目配置 和 相同的编辑器但不同的设置的问题。

解决办法

找了工作电脑上运行良好的项目,复制了 eslint 的相关文件到迁移过来的项目中。

当然这种做法有局限性,如果迁移过来的是一个复杂的多成员合作项目,就不能轻易的修改其校验规则。我要迁移的只是一个练习 demo 倒是无妨这样简单粗暴。

 

编辑器相关设置

使用的是vscode编辑器。我两台电脑的编辑器配置是一样的,就省了这一步。不过还是记录下备忘。

settings.json

{
  "workbench.colorTheme": "Default Dark+",
  "editor.lineNumbers": "on", //开启行数提示
  "workbench.editor.enablePreview": false, //打开文件不覆盖
  "editor.detectIndentation": false, // vscode默认启用了根据文件类型自动设置tabsize的选项
