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

我在Windows 10上的Node 12.19.0和yarn 1.22.5中发现了同样的问题。我通过安装最新的稳定64位python并在python安装期间将路径添加到环境变量来解决这个问题。在安装python之后,我重启了我的机器以获取env vars。

其他回答

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

如果节点版本更新,NPM -g将工作。我遇到了这个问题,npm install -g——production windows-build-tools作为临时解决方案。但是从长期来看,升级Node.js、NPM和相关的包版本是一个更好的选择。

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。

嘿,我通过以下步骤解决了这个错误

第一次卸载python 3.8.6(最新版本) 然后我安装了python 2.7.1(任何python 2版本都可以,但不要太旧,这是推荐的) 然后我将c:\python27添加到环境变量中 我的操作系统是windows,所以我按了这个链接 它工作

节点15.x。X,和"node-sass": "^4.11.0"。 我在node-sass的发布说明中看到了node-sass 4.11.0兼容的节点最高版本是11,所以我卸载了node并重新安装11.15.0版本(我使用的是Windows)。 检查node-sass释放。 (这是你应该在node-sass版本中看到的。)

希望这对你有所帮助,抱歉我的英语不好:)
