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。


当前回答

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

其他回答

node-sass已于2020年10月26日弃用

不需要安装旧版本的Python,只需迁移到dart.sass即可

对于我的ReactJS项目(npm),以下步骤对我有效:

从项目中删除node_modules 在包中。Json,删除这个 依赖: “依赖”:{ …, :“node-sass ^ 3.0.0”, ... } NPM install——save-dev sass npm安装 现在尝试使用npm start运行你的项目 如果你收到一个类似于"To import Sass files, you first need To install node-sass"的错误,执行如下命令: NPM安装node-sass@npm:sass

如果你正在使用yarn,执行相同的命令,但在最后一步执行这个命令,如下所述: 纱线拆卸节点 纱加纱


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)

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

gyp ERR! stack Error: Command failed: C:\Python310\python.EXE -c import sys; print "%s.%s.%s" % sys.version_info[:3];
gyp ERR! stack   File "<string>", line 1
gyp ERR! stack     import sys; print "%s.%s.%s" % sys.version_info[:3];
gyp ERR! stack                 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
gyp ERR! stack SyntaxError: Missing parentheses in call to 'print'. Did you mean print(...)?

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

在我的情况下,我有节点版本v16安装在机器上,但react项目使用node-sass版本v4.x。x,更新包。node-sass版本到v6.0.1的Json解决了这个问题, Node -sass的节点版本支持可以从NPM官方页面:https://www.npmjs.com/package/node-sass查看
