Node.js：由于node-sass和node-gyp，Python没有findexception

突然在我的jenkins环境之一构build已经开始失败，而在本地机器似乎工作正常，因为我已经安装了python，

从日志中，我能够检测到问题是与内部依赖关系是node- gyp v3.5.0从node-sass v3.8.0，当我通过访问这个关于node- gyp的研究并find了Python需要安装的先决条件。

所以我的问题是，我可以安装什么版本的节点sass来绕过这个，或者是有更好的解决scheme，因为我的构build运行良好，直到今天早上在相同的环境。

节点v5.10.1

任何想法都非常感谢，谢谢。

在安装时，Node-sass会尝试为您的平台下载二进制文件。 节点5由3.8 https://github.com/sass/node-sass/releases/tag/v3.8.0支持如果您的Jenkins无法下载预编译的二进制文件，那么您需要遵循Node-gyp上的平台要求自述文件（Python2，VS或MSBuild，…）如果可能的话，我会build议更新您的节点至less6，因为5不再支持节点。 如果你想升级到8，你需要更新node-sass到4.5.3
