Node.js 如何仅在macOS上运行package.json postinstall脚本

我必须在MacOS上执行此

postinstall

脚本（修复react native maps中的临时错误）：

Linux或Windows上不需要它，因此如何仅在macOS上执行它？

npm软件包似乎完全可以使用package.json执行您想要的操作，即：

"scripts": {
  "foo": "cross-os bar",
  "bar": {
    "darwin": "echo 'i will only run on Mac'",
    "win32": "echo 'i will only run on Windows'",
    "linux": "echo 'i will only run on Linux'"
  }
}

因此，在您的情况下：

"scripts": {
  "postinstall": "cross-os bar"
}
"cross-os": {
  "bar": {
    "darwin": "echo 'i will only run on Mac'",
    "win32": "echo 'i will only run on Windows'",
    "linux": "echo 'i will only run on Linux'"
  }
}

例如回购协议；命名显然会反映您的用例等。

这是一个很好的解决方案。我会把这个问题留1-2天，以防有人找到一个“普通”的解决方案。不用担心，我想有一个更简单的方法，不添加dep

"scripts": {
  "postinstall": "cross-os bar"
}
"cross-os": {
  "bar": {
    "darwin": "echo 'i will only run on Mac'",
    "win32": "echo 'i will only run on Windows'",
    "linux": "echo 'i will only run on Linux'"
  }
}
