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。

我的操作系统是win10 x64。在进行npm安装时也发现了类似的问题。

检查节点版本号是否与node-sass版本号一致。(参考以上表格)如果需要，升级或降级节点版本删除“node_modules”文件夹 install node-sass@ $ NPM install

做得很好。

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         |

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

我正在使用Windows 11，我曾尝试使用npm I -g Windows -build-tools，但它永远卡住了。所以，对我有用的是:

从这里安装Visual Studio Build tools 2017。安装完成后，以管理员身份打开Powershell。输入命令:npm install——global——production windows-build-tools——vs2015 以后谢谢我!

它修复了我在Windows 11上与构建工具相关的所有错误。

错误信息意味着它无法定位您的python可执行文件或二进制文件。

在许多情况下，它安装在c:\python27。如果它还没有安装，你可以用NPM install——global windows-build-tools安装它，只有在它还没有安装的时候才会工作。

将其添加到环境变量中并不总是有效。一个更好的选择是在npm配置中设置它。

“C:\Python27\python.exe”
