无法在 MacOS 上安装 TypeScript - 终端错误

【中文标题】无法在 MacOS 上安装 TypeScript - 终端错误

【英文标题】：Can't install TypeScript on MacOS - Terminal Error

【发布时间】：2018-12-09 12:55:03

【问题描述】：

我的 Mac 上有 Visual Studio Code，并想为 Angular 安装 TypeScript。我认为我之前已经安装了 Node.js 或 Git。如果 TypeScript 网站上的这个命令在 Mac 终端中运行，它应该会安装 TypeScript，但它不会：

npm install -g typescript

如果我将其粘贴到终端并按回车，则此错误代码会出现在终端中：（这是什么问题？我真的不明白，对终端一无所知，我不是电脑亲。如果您有一些针对初学者的简单提示，那将是一个很大的帮助。谢谢！！）

【问题讨论】：

你需要使用sudo

【参考方案1】：

npm WARN checkPermissions 缺少对 /usr/local/lib/node_modules 的写入权限

意味着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使用 root 权限安装了 nodejs/npm。

sudo npm install -g typescript

然后输入你的密码

我还没有足够的支持声望，但非常感谢您的帮助。似乎它奏效了。我认为终端的响应应该没问题：/usr/local/bin/tsc -> /usr/local/lib/node_modules/typescript/bin/tsc /usr/local/bin/tsserver -> /usr/local/lib/node_modules/typescript/bin/tsserver + typescript@2.9.2 added 1 package from 1 contributor in 1.177s MacBook-Pro:~

你是什么意思，你能说得更详细一点吗？ :-)（我对***和编码还是很陌生）

永远不要对节点包使用 sudo。特别是使用 npm 或此类库。
