建立vue项目遇到的一些问题

初始化vue项目过程整理

第一次建立vue项目，刚开始就出了问题

用命令行vue init ex3建立vue项目，运行npm run dev，出现报错

 ERROR  Failed to compile with 9 errors

  0% compiling

尝试过网上介绍的各种方法，比如安装依赖：

npm install stylus-loader css-loader style-loader --save-dev
npm install less less-loader --save-dev
npm install sass sass-loader --save-dev

或者删除项目中的node_modules后重新用npm install安装依赖，然后再次执行npm run dev，仍然报错，且错误相同
最后发现是路径上文件名的问题…
把路径上的中文名和特殊符号去掉后就可以成功运行了

终于可以开始愉快的学习vue啦:-D
