macos - 无法在 MacOS 上安装 TypeScript - 终端错误

Question

我的 Mac 上有 Visual Studio Code，想为 Angular 安装 TypeScript。我认为我之前已经安装了 Node.js 或 Git。来自 TypeScript 网站的这条命令如果在 Mac 终端中运行，应该会安装 TypeScript，但它不会:

npm install -g typescript

如果我将它粘贴到终端并按回车键，这个错误代码会出现在终端中:(有什么问题？我真的不明白，对终端一无所知，我不是电脑亲。如果您有针对初学者的简单单词提示，将是一个很大的帮助。谢谢!!)

Answer 1

npm WARN checkPermissions Missing write access to /usr/local/lib/node_modules

表示您需要权限才能下载到该位置，它需要 root 权限的原因可能是因为您安装了具有 root 权限的 nodejs/npm。

sudo npm install -g typescript

然后输入密码
