上面的错误一共是分为了两类,一类是访问https://registry.npmjs.org/json-server failed这个地址的时候失败,可能是这个地址是在国外吧,就跟我去node.js官网下载软件多次下载失败一样, 还有一类错误是没有权限访问node_global这个文件夹,这个文件夹在哪里呢,就是在安装的node.js文件下,如果没有的话可以自己新建一个,然后再给这个文件夹设置权限.
先说给文件夹设置权限的问题,右键属性选择安全,点击编辑,然后给所有的组或用户名勾选完全控制的权限.
另外一种错误是访问地址失败,请求连接超时,(今天学习axios时，使用 json-server 搭建 REST API。需要npm install -g json-server， 在vscode中执行npm install -g json-server，安装进度条走了一半时报错)
是否是网络问题？然后npm config list查看下镜像地址：
找这哥镜像地址
然后输入一遍后没有找到,提示再使用以下命令查看全部npm config ls -l
找到
用的是npm官方服务器，随后执行下面命令：
npm config set registry https://registry.npm.taobao.org/
npm config get registry https://registry.npm.taobao.org/
切换为淘宝镜像,以上两条命令都要执行
修改成了
然后再次执行json -server 安装命令就可以了.
