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

当前回答

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",

其他回答

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

我在Windows 10上的Node 12.19.0和yarn 1.22.5中发现了同样的问题。我通过安装最新的稳定64位python并在python安装期间将路径添加到环境变量来解决这个问题。在安装python之后，我重启了我的机器以获取env vars。

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>

我的机器是Windows 10，我在尝试使用node-sass包编译SASS时遇到过类似的问题。我的节点版本是v10.16.3, npm版本是6.9.0

我解决这个问题的方法是:

首先删除package-lock。Json文件和node_modules/文件夹。以管理员身份打开Windows PowerShell。执行命令npm i -g node-sass。之后，进入项目文件夹并运行npm install 最后，运行SASS编译脚本，在我的例子中，它是npm run build:css

而且很管用!!

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)
