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

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。

其他回答

您需要按照以下步骤来修复该错误:

    1: DELETE node_modules
    2: npm install node-sass@<version-as-per-below-table>
    3. npm install

每个node-sass版本都对应于特定的Node.JS版本。

下面是node-sass的最小和最大支持版本的快速指南(查看下表的更新):

| NodeJS  | Supported node-sass version | Node Module |
|---------|-----------------------------|-------------|
| Node 16 | 6.0+                        | 93          |
| Node 15 | 5.0+                        | 88          |
| Node 14 | 4.14+                       | 83          |
| Node 13 | 4.13+, <5.0                 | 79          |
| Node 12 | 4.12+                       | 72          |
| Node 11 | 4.10+, <5.0                 | 67          |
| Node 10 | 4.9+, <6.0                  | 64          |
| Node 8  | 4.5.3+, <5.0                | 57          |
| Node <8 | <5.0                        | <57         |

下面是帮助我防止在运行基于旧node-gyp v3.8.0的项目时出现错误error: not found: python2的方法。

运行npm install——global——production windows-build-tools@4.0.0 将python.exe重命名为%USERPROFILE%\.windows-build-tools\python27中的python2.exe 确保%USERPROFILE%\。windows-build-tools\python27是PATH环境变量的一部分(这是windows-build-tools应该已经为你做的) 下载Visual Studio 2017构建工具 告诉npm使用VS 2017, npm配置msvs_version 2017 运行使用node-gyp的脚本(node-gyp现在会找到python2.exe)

可选:强制升级node-gyp

您还可以尝试将项目升级为使用node-gyp v8.0.0而不是node-gyp v3.8.0。在这种情况下，在package.json中添加以下决议项:

  "resolutions": {
    "node-gyp": "8.0.0"
  }

之后，确保安装了Python 3和Visual Studio 2017构建工具和/或Visual Studio 2019构建工具。你也可以执行npm config delete msvs_version命令让node-gyp自动检测你的VS版本。

测试:

Windows 10 Pro Build 19042.985 node . js v15.14.0 npm v7.7.6 Node-gyp -v v3.8.0。

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。

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!!

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
