cnpm run dev运行报错

Question

新手，跟着菜鸟教程做了一次Vue.js的项目建立，先从安装完node.js开始。
然后我进入控制台开始打命令，第一个验证了下npm的安装，看了下版本，
第二个用了“cnpm install npm -g”，
第三个到D盘建了个目录，用了“cnpm install vue”，
第四个用了“cnpm install --global vue-cli”，
第五个用了“vue init webpack my-project”，
第六个到my-project文件夹，用了“cnpm install”，
它提示了一个警告，我查了一下有网友是sass的问题，于是乎我多用了一个命令“cnpm rebuild node-sass”，然后重新“cnpm install”，通过了
最后我在用“cnpm run dev”这里最后一步就出错了……
下边是错误截图：

然后照着某位网友的提示我去查看了依赖和文件结构，没有发现问题……
下边放图：

百思不得其接的我最后还是选择起来求助一下吧=-=希望有好运气

刚刚看到有人提到了babel等东西，我看我还是把package发一发吧

Answer 1

你的babel和node-sass、sass-loader都没在你的package.json里面看到，把那些也装上

Answer 2

安装完node.js应该先测试一下node -v看版本，npm是nodejs赠送给你的不需要重新装
