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

两种方案(2021年12月):

1 -你不能升级“node-sass”包! 安装python2并修改其.exe文件名。 修复PATH env变量记录顺序(详细信息如下)。 2 -更新node-sass包。

先决条件

您将Node.JS更新到Windows 10上的最新版本(v16.13.1)。 你在你的项目文件夹中运行yarn install或npm install,并收到一个错误(见下文)。

选项1。安装Python-2并修复PATH环境

参见MSI安装程序

安装后

注意!如果在x64上出现以下错误,请尝试从x64重新安装最新的Node.js到x86。(但在x86上,你也可能会收到内存限制错误。)

Error: Node Sass does not yet support your current environment: Windows 64-bit with Unsupported runtime (93)

在PATH env变量中使用Python

Python 3的记录必须高于Python 2的记录!

将python.exe拷贝到python2.exe

第二个选项。升级node-sass包

在包中。json文件

修改方案。在你的项目文件夹上运行yarn install或NPM install。 其他文件将自动更新。

之前

在更新:

或者使用yarn或npm CLI来做同样的事情,但这可能会显著改变你的.lock文件。

更新后,你可能会意识到你还需要更新sass-loader, webpack等。

你可能遇到的错误(供参考)

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。

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:)

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。

windows 11机器的一个简单解决方案是,

删除package-lock。Json文件和node_modules/文件夹。 以管理员身份打开Windows终端。 执行命令npm i -g node-sass。 进入项目文件夹并运行npm install 现在用npm start运行项目

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
