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。

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。

嘿，我通过以下步骤解决了这个错误

第一次卸载python 3.8.6(最新版本) 然后我安装了python 2.7.1(任何python 2版本都可以，但不要太旧，这是推荐的) 然后我将c:\python27添加到环境变量中我的操作系统是windows，所以我按了这个链接它工作

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

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         |

我的答案可能并不适用于所有人。节点版本号:v10.16.0 NPM: 6.9.0

我在使用node-sass和node-sass-中间件时遇到了很多麻烦。它们是有趣的包，因为它们被广泛使用(每周有数百万次下载)，但它们的github显示出有限的依赖性和覆盖范围。我当时正在更新自己开发的一个旧平台。

我最后不得不做的是:

1)手动删除node_modules

2)手动删除package-lock.json

3) sudo NPM install node-sass——not - safe-perm=true——allow-root

4) sudo NPM install node-sass-middleware——not - safe-perm=true——allow-root

我得到了以下帮助，谢谢!
