找不到semver这个模块,加上去试试应该就可以了

楼主,请问这个怎么解决

如果环境变量配置没问题的话,能使用"node --version"指令的话。

1、切换npm镜像:在任意路径下用cmd输入“npm install -g cnpm --registry=https://registry.npm.taobao.org”。

2、npm全局安装vue:仍旧在任意路径的cmd下输入“cnpm install vue-cli -g”,安装vue。成功后输入vue能出来信息。

3、npm项目依赖组件安装:cmd进入前端vue项目的根目录,输入命令“cnpm install”,会根据前端项目的依赖关系下载好相关的组件,存在项目目录的node_modules文件夹下。

完成上述步骤应该就可以了,我中间在执行“cnpm install”时出现了卡死现象 我用“Ctrl+Z”还是Ctrl+C”忘了 ,然后重新执行”cnpm install”就OK了_**_
