gyp verb check python checking for Python executable “python2” in the PATH和win32-x64-57_binding.node错误解决方法

今天在boot-cms项目下执行npm install时出现如下错误，全部执行记录如下：

发现有一行提示：

Downloading binary from https://github.com/sass/node-sass/releases/download/v3.13.1/win32-x64-57_binding.node

Cannot download "https://github.com/sass/node-sass/releases/download/v3.13.1/win32-x64-57_binding.node":

HTTP error 404 Not Found

在 node scripts/install.js 之后发现这么一句话

Cannot download "https://github.com/sass/node-sass/releases/download/v4.5.3/win32-x64-57_binding.node":

在网上下载，如果报错的版本和我的一样，可以用我下载好的文件  点击下载

下载完了之后把它注册成全局环境变量，两种方式：

第一种：直接右键我的电脑–》属性–》高级系统设置–》环境变量–》添加

第二种：set XXX=文件路经–》set SASS_BINARY_PATH=F:\ww\tools\node-sass\win32-x64-57_binding.node

查看环境是否合适：echo %SASS_BINARY_PATH%

如果打印出来您配置好的文件地址那就ok了，

最后再来试试安装：npm i -g node-sass

总结：

笔者经过多种不同环境，不同错误的尝试，大概总结如下，

1、个别时是因国内网速问题，导致无法正常安装。

2、使用添加至环境变量的解决方法，基本能解决问题。

3、使用添加环境变量的方法解决时要注意node-sass版本的要与nodejs的版本相一致。

以下是查看node-sass相对应 binding.node版本 的方法

https://www.npmjs.com/package/node-sass

（1）使用node -v 查看nodejs版本：

（2）另附node-sass的最新版本
