突然在我的一个jenkins环境构建已经开始失败,而在本地机器,它似乎工作得很好,因为我有python安装,

从日志中,我能够检测到问题是内部依赖关系,即node-gyp v3.5.0从node-sass v3.8.0,当我通过访问这篇关于node-gyp的文章进行研究时,我发现了Python需要安装的先决条件。

所以我的问题是,我可以安装哪个版本的node-sass来绕过这个,或者有更好的解决方案,因为我的构建在相同的环境上运行良好,直到今天早上。

节点v5.10.1

任何想法都非常感激,谢谢。


当前回答

错误信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。 如果它还没有安装,你可以用NPM install——global windows-build-tools安装它,只有在它还没有安装的时候才会工作。

将其添加到环境变量中并不总是有效。 一个更好的选择是在npm配置中设置它。

“C:\Python27\python.exe”

其他回答

这是两年前的,但没有一个能帮到我。

我卸载了我的NodeJS v12.8.1 (Current),并安装了一个全新的v10.16.3 (LTS),我的ng build——prod工作了。

在最新的Node.js LTS版本:18.13.0的Windows 11上得到这个错误(包括npm 8.19.3)

https://nodejs.org/en/download/

修复了第一次手动下载Python 2.7.18,因为只安装了Python 3.11。

https://www.python.org/downloads/windows/

https://www.python.org/downloads/release/python-2718/

安装后,我从@bvdb运行命令:

npm config set python "C:\Python27\python.exe"

https://stackoverflow.com/a/64486670/3850405

这修复了错误

我在一台Windows 11机器上,为了修复它,我自己下载了python27,使用这个链接:https://www.python.org/download/releases/2.7/。

安装完成后,我运行了这个命令:

npm config set python c:\python27\python.exe

Node-sass在安装时尝试为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 如果你的Jenkins无法下载预构建的二进制文件,那么你需要遵循Node-gyp README上的平台要求(Python2, VS或MSBuild,…) 如果可能的话,我建议将Node更新到至少6,因为Node不再支持5了。 如果你想升级到8,你需要将node-sass更新到4.5.3

对于yarn项目,使用"yarn install——ignore-engines"忽略节点版本将安装任何node-sass v.而不会出现这些python错误
