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

当前回答

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。

其他回答

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。

Python2维护状态为“生命结束”,因此在新的ubuntu版本中默认不会安装。

安装最新的python2.7对我来说效果很好。

以下是安装说明:

下载python2.7: https://www.python.org/ftp/python/2.7.18/Python-2.7.18.tgz 从下载的。tgz安装:

tar -xf Python-2.7.18.tgz
cd Python-2.7.18
./configure --enable-optimizations
sudo make altinstall

打开一个新终端并再次尝试npm安装

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

如果你使用Visual Studio。遵循以下步骤:

npm cache clean --force
npm config set msvs_version 2019 --global
npm install node-sass

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!
