你能帮我解决吗？

【问题讨论】：

请澄清您的具体问题或提供其他详细信息以准确突出您的需求。正如目前所写的那样，很难准确地说出你在问什么。

标签： node.js npm npm-install node-gyp gyp

【解决方案1】：

是node-sass 导致您的npm install 错误。

原因：

node-sass 是一个 npm 包，使用 C/C++ 构建，安装后需要安装预构建的二进制文件或从源代码编译。

在您的情况下，未成功下载预构建的二进制文件，因此 npm 尝试从源代码构建 node-sass，这需要 python2.但是你的系统没有安装python2。

解决方案：

要解决此问题，您有 3 个选项：

修复你的网络配置（从 Github 下载预构建文件）或使用sass_binary_site 更改 node-sass 预构建二进制站点，例如在中国你可以尝试淘宝镜像：sass_binary_site=https://npm.taobao.org/mirrors/node-sass。如果 npm 可以下载预编译的文件，就不会再编译了。
安装python2。
将 npm 依赖项从 c/c++ node-sass 更改为纯 JavaScript 替代方案，例如 sass。
