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。

当前回答

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

其他回答

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)

我不得不:

Delete node_modules
Uninstall/reinstall node
npm install node-sass@4.12.0

在强制它到正确的sass版本后工作得很好，根据版本说正在与正确的节点一起工作。

NodeJS  Minimum node-sass version   Node Module
Node 12 4.12+   72
Node 11 4.10+   67
Node 10 4.9+    64
Node 8  4.5.3+  57

还有许多其他错误，似乎是由错误的sass定义版本引起的。

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>
2022-08-19 17:13:42

Node-sass在安装时尝试为平台下载二进制文件。节点5由3.8 https://github.com/sass/node-sass/releases/tag/v3.8.0支持 如果你的Jenkins无法下载预构建的二进制文件，那么你需要遵循Node-gyp README上的平台要求(Python2, VS或MSBuild，…) 如果可能的话，我建议将Node更新到至少6，因为Node不再支持5了。 如果你想升级到8，你需要将node-sass更新到4.5.3

2017-08-22 00:51:13

对于yarn项目，使用"yarn install——ignore-engines"忽略节点版本将安装任何node-sass v.而不会出现这些python错误
