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

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。

其他回答

如果你使用Visual Studio。遵循以下步骤:

npm cache clean --force
npm config set msvs_version 2019 --global
npm install node-sass

看了所有的答案后,我发现这个解决方案可能非常有用。它解释了在安装node-sass时如何配置“npm”来找到你安装的python版本。记住,node-sass需要node-gyp(一个npm构建工具)来查找你的python路径。或者只是安装python,并遵循相同的解决方案(在链接中)。谢谢。

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。

去包装。Json和更改

"node-sass": "4.14.1",

with

"node-sass": "^7.0.1",

它为我工作之后,我可以运行NPM安装

换句话说,您需要使用支持最新python版本的最新包。

注意:Node Saas 7.0.1兼容"react-scripts": "5.0.0"如果你的包。Json有“react-scripts”:“4.0.0”,然后将其更改为

 "react-scripts": "5.0.0", 

我们在2021年设置一个新的TeamCity构建代理时遇到了这个问题。最初我们使用Chocolatey安装了nodejs。我们重新安装回到原来的安装节点-v12.12.0-x64.msi。安装程序对话框中的第三个屏幕提供了安装编译本机模块所需的工具:

这样做之后,我们的问题就解决了。
