Node.js:由于节点sass和not，Python没有找到异常。
Node.js:由于节点sass和not，Python没有找到异常。
提问于 2017-08-21 16:02:37
突然，在我的一个jenkins环境中，构建开始失败，而在本地机器上，它似乎运行良好，因为我已经安装了python，
从日志中，我能够检测到问题在于内部依赖，即节点-gyp v3.5.0与节点-sass v3.8.0之间的依赖关系，当我通过访问有关节点-gyp的这进行研究时，发现了需要安装这的先决条件。
因此，我的问题是，我可以安装哪个版本的节点-sass来绕过它，或者是否有一个更好的解决方案，因为我的构建在相同的环境中一直运行到今天早上。
Node v5.10.1

节点-sass尝试在安装时为您下载二进制文件。节点5由3.8 https://github.com/sass/node-sass/releases/tag/v3.8.0支持，如果您的Jenkins无法下载预构建的二进制文件，那么您需要遵循Node-gyp自述的平台需求(Python2，VS或MSBuild，.)如果可能的话，我建议将您的Node更新到至少6，因为Node不再支持5。如果您想升级到8，则需要将节点-sass更新为4.5.3。

这件事最近发生在我的窗户上。我使用具有管理权限的PowerShell来修复它，方法如下：
- 删除
node_modules文件夹 - 以管理权限运行
npm install --global windows-build-tools。(在我的情况下，需要重新启动-并且无需询问就重新启动！) - 用
npm install重新安装节点模块或节点-sass

错误消息意味着它无法定位您的python可执行文件或二进制文件。
在许多情况下，它安装在c:\python27 27上。如果它还没有安装，你可以用npm install --global windows-build-tools安装它，只有当它还没有安装的时候才能工作。
将其添加到环境变量并不总是有效的。另一种更好的选择是将其设置在npm配置中。
npm config set python "C:\Python27\python.exe"
