React 模块安装失败

Question

我正在尝试通过 yarn 和 npm 安装 sass-loader 和 node-sass，但遇到相同的错误。

我尝试使用其中一种：

yarn add sass-loader@6.0.6 node-sass@4.5.3
npm install sass-loader@6.0.6 node-sass@4.5.3

但两者都会产生类似的错误。这是纱线的回应：

编辑：我正在使用 Windows。设置 python 的路径后，这是我得到的响应：

我已尝试下载 python 2.7，如其中一个错误中所述。但是错误仍然是一样的。我坚持了 3 个小时，希望能得到一些帮助。

可能是一些权限的东西吗？我不明白为什么会发生这种情况，因为我只是一步一步地遵循基本教程。

Answer 1

node-gyp 在 Windows 上构建失败是很常见的情况。 要使构建通过，请按照official documentation中描述的步骤进行操作

完成这项工作的最简单方法是使用npm 或yarn 安装windows-build-tools

npm install --global --production windows-build-tools

然后再次尝试安装node-sass 和sass-loader

使用Bash on Ubuntu on windows也可以解决问题

Answer 2

我认为错误清楚地表明 python 没有添加到您的环境变量中，或者它甚至没有安装在系统上。请解决python依赖并重试。
