无法安装 json-server

Question

我正在尝试安装 JSON-Server，但它不起作用！

我使用了以下命令：npm install -g json-server

这是错误信息：

npm ERR! code EACCES
npm ERR! syscall mkdir
npm ERR! path /usr/local/lib/node_modules/json-server
npm ERR! errno -13
npm ERR! Error: EACCES: permission denied, mkdir '/usr/local/lib/node_modules/json-server'
npm ERR!  [Error: EACCES: permission denied, mkdir '/usr/local/lib/node_modules/json-server'] {

npm ERR!   syscall: 'mkdir',
npm ERR!   path: '/usr/local/lib/node_modules/json-server'
npm ERR! }
npm ERR!

尝试在命令前使用 sudo ：
