无法从自制软件安装watchman

Question

我刚刚开始使用 React Native 开发应用程序。当我尝试设置时，我成功下载了自制程序，但无法使用以下命令安装 watchman 或节点：

brew install node
brew install watchman

这是我得到的结果：

==> Searching for similarly named formulae...
Error: No similarly named formulae found.
Error: No available formula or cask with the name "watchman".
==> Searching for a previously deleted formula (in the last month)...
Error: No previously deleted formula found.
==> Searching taps on GitHub...
Error: No formulae found in taps.

有人知道如何解决这个问题吗？
