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

在最新的Node.js LTS版本:18.13.0的Windows 11上得到这个错误(包括npm 8.19.3)

https://nodejs.org/en/download/

修复了第一次手动下载Python 2.7.18，因为只安装了Python 3.11。

https://www.python.org/downloads/windows/

https://www.python.org/downloads/release/python-2718/

安装后，我从@bvdb运行命令:

npm config set python "C:\Python27\python.exe"

其他回答

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。

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)

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         |

Node-sass在安装时尝试为平台下载二进制文件。节点5由3.8 https://github.com/sass/node-sass/releases/tag/v3.8.0支持如果你的Jenkins无法下载预构建的二进制文件，那么你需要遵循Node-gyp README上的平台要求(Python2, VS或MSBuild，…) 如果可能的话，我建议将Node更新到至少6，因为Node不再支持5了。如果你想升级到8，你需要将node-sass更新到4.5.3

2017-08-22 00:51:13

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
