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

当前回答

我的操作系统是win10 x64。 在进行npm安装时也发现了类似的问题。

检查节点版本号是否与node-sass版本号一致。(参考以上表格)如果需要,升级或降级节点版本 删除“node_modules”文件夹 install node-sass@ $ NPM install

做得很好。

其他回答

使用npm 6.14.12降级到节点10.24.1版本对我来说是可行的。 随着安装windows-build-tools使用

NPM I -g windows build-tools

上面的答案没有一个能解决我的问题,它比我想象的要简单得多。

只需降低您的节点版本,以匹配node-sass版本:

nvm list
nvm user <node-version>

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", 

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。
