我不知道该怎么做我也尝试安装 node-sass 但没有用

Answer 1

我有一个类似的问题。 尝试删除 package-lock.json 然后重新运行“npm install”。

Answer 2

npm 错误有时可能非常（可以说，过度）冗长。 错误的有趣部分是：

npm ERR! gyp verb check python checking for Python executable "python2" in the PATH

您尝试安装的 package 具有使用 gyp 在本地编译的本机部分，作为其工具的一部分，npm 需要 python2 来执行构建。
您需要确保已安装 python2，并且可执行文件是路径的一部分。

或者，如果您安装了 python 但名称不同，您可以通过调用告诉 npm 要使用哪个可执行文件

npm config set python /path/to/your/python

Answer 3

我昨天有一个类似的问题。 我通过确保在默认目录中下载了 python 并安装 Windows 构建工具来修复它，因为 node-sass 需要 node-gyp 而反过来需要 Windows 构建工具。

您可以使用管理员 shell 下载它，但 go 到此页面同样容易，然后找到并下载“Visual Studio 构建工具”。 在这里也可以找到一个很好的视频来解释这个过程。 如前所述，您可以使用 powershell 安装它，前提是它以管理员身份运行，这个过程可以在它的 npm 页面上找到。

完成此操作后，可能值得删除您的节点模块文件夹并重新运行 npm 安装。
