Node.js:由于node-sass和node-gyp, Python没有发现异常

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。

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。

同样的问题，在我的电脑上安装不同版本的python时浪费了几个小时。简单地升级节点到最新版本v8.11.2和npm 5.6.0，然后安装node-sass@4.5.3，你就可以了。

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)

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

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
2022-02-10 19:31:43

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
