vue-cli从2升级到3报错error 404 Not Found: @wry/context@^0.4.0

vue3出来了，想尝尝鲜。

于是按官方的方法卸载2安装3.

npm uninstall vue-cli -g

npm install -g @vue/cli

但是报错了 error 404 Not Found: @wry/context@^0.4.0

一脸懵逼。。。

网上搜索之，并没有什么参考资，只得自己一步一步排除。

一，于是检查Node.js版本，推荐 8.11.0+

node -v

没有问题

二，删掉原来node全局配置的vue-cli并使用管理员的cmd

还是存在问题

解决办法： nrm的基本用法

原来我使用了nrm 管理 npm源的问题

设置了 npm 实际是指向了淘宝的

将源改为官方的

重新安装：

npm install -g @vue/cli

D:\>nrm use npm

   Registry has been set to: https://registry.npmjs.org/

D:\>npm install -g @vue/cli
