node.js - 运行 npm install 给我这些错误

Question

我尝试了很多方法来解决这个问题，但找不到解决方案，安装的 node sass 只是增加了更多问题，它以前运行没有问题，现在我不断收到错误

我不知道该怎么做我也尝试安装 node-sass 但没有成功

npm 错误有时会非常(可以说是过于)冗长。错误的有趣部分是:

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

您尝试安装的包有一个使用 gyp 在本地编译的 native 部分，作为其工具的一部分，npm 需要 python2 来执行构建。
您需要确保安装了 python2，并且可执行文件是路径的一部分。

或者，如果你安装了 python 但它的命名不同，你可以通过调用告诉 npm 使用什么可执行文件

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