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。

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

在我的情况下，我有节点版本v16安装在机器上，但react项目使用node-sass版本v4.x。x，更新包。node-sass版本到v6.0.1的Json解决了这个问题， Node -sass的节点版本支持可以从NPM官方页面:https://www.npmjs.com/package/node-sass查看

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

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)

Python2维护状态为“生命结束”，因此在新的ubuntu版本中默认不会安装。

安装最新的python2.7对我来说效果很好。

以下是安装说明:

下载python2.7: https://www.python.org/ftp/python/2.7.18/Python-2.7.18.tgz 从下载的。tgz安装:

tar -xf Python-2.7.18.tgz
cd Python-2.7.18
./configure --enable-optimizations
sudo make altinstall

打开一个新终端并再次尝试npm安装

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。
