npm install -g 打字稿失败

Question

当我运行 npm install -g typescript 显示以下消息时：

npm ERR! code EACCES
npm ERR! syscall mkdir
npm ERR! path /usr/local/lib/node_modules/typescript
npm ERR! errno -13
npm ERR! Error: EACCES: permission denied, mkdir '/usr/local/lib/node_modules/typescript'
npm ERR!  [Error: EACCES: permission denied, mkdir '/usr/local/lib/node_modules/typescript'] {
npm ERR!   errno: -13,
npm ERR!   code: 'EACCES',
npm ERR!   syscall: 'mkdir',
npm ERR!   path: '/usr/local/lib/node_modules/typescript'
npm ERR! }
npm ERR!
npm ERR! The operation was rejected by your operating system.

npm ERR! A complete log of this run can be found in:

我尝试检查我是否已成功安装 TypeScript，如果我运行 npm ls typescript 它显示：

alexz@ /Users/alexz
└── typescript@4.5.4

我很困惑是否安装了 TypeScript，因为如果我安装了 tsc -v，它会告诉我 tsc 命令未找到。我该如何解决上述问题？谢谢！

这是一个权限问题。使用 sudo 命令，它会询问您的计算机密码。
