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"

这修复了错误

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", 

node-gyp需要旧的Python 2 - link

如果你没有安装它-检查其他关于安装windows-build-tools的答案。

如果您像我一样,同时安装了旧版本和新版本的Python, node-gyp很可能会尝试使用Python 3。这将导致以下SyntaxError:无效语法错误。

我找到了一篇关于安装两个Python版本的文章。他们建议重命名Python 2。*可执行文件到python2.exe - link。

因此,node-gyp似乎希望找到重命名的旧Python 2可执行文件。因此出现错误消息:

...
gyp verb check python checking for Python executable "python2" in the PATH
gyp verb `which` failed Error: not found: python2
...

一旦我将C:\Python27\python.exe重命名为C:\Python27\python2.exe,它就能正常工作,没有错误。

当然,C:\Python27\和C:\Python39\都必须在PATH变量中。并且不需要在npm配置中设置旧的Python版本。你的默认Python仍然是新的。

这是两年前的,但没有一个能帮到我。

我卸载了我的NodeJS v12.8.1 (Current),并安装了一个全新的v10.16.3 (LTS),我的ng build——prod工作了。

如果节点版本更新,NPM -g将工作。我遇到了这个问题,npm install -g——production windows-build-tools作为临时解决方案。但是从长期来看,升级Node.js、NPM和相关的包版本是一个更好的选择。

在2022年为我工作,实际上我们可以通过npm安装python 2.7 在安装python 2.7之后,我们可以使用python 2.7强制运行npm install with

Sass

NPM install——global windows-build-tools——save NPM install——python=python2.7
