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

当前回答

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

其他回答

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!

未为grpc@1.10.1和node@10.9.0找到预构建的二进制文件

错误:EACCES:当尝试使用npm安装ESLint时，权限被拒绝

我不得不:

Delete node_modules
Uninstall/reinstall node
npm install node-sass@4.12.0

在强制它到正确的sass版本后工作得很好，根据版本说正在与正确的节点一起工作。

NodeJS  Minimum node-sass version   Node Module
Node 12 4.12+   72
Node 11 4.10+   67
Node 10 4.9+    64
Node 8  4.5.3+  57

还有许多其他错误，似乎是由错误的sass定义版本引起的。

下面是帮助我防止在运行基于旧node-gyp v3.8.0的项目时出现错误error: not found: python2的方法。

运行npm install——global——production windows-build-tools@4.0.0 将python.exe重命名为%USERPROFILE%\.windows-build-tools\python27中的python2.exe 确保%USERPROFILE%\。windows-build-tools\python27是PATH环境变量的一部分(这是windows-build-tools应该已经为你做的) 下载Visual Studio 2017构建工具 告诉npm使用VS 2017, npm配置msvs_version 2017 运行使用node-gyp的脚本(node-gyp现在会找到python2.exe)

可选:强制升级node-gyp

您还可以尝试将项目升级为使用node-gyp v8.0.0而不是node-gyp v3.8.0。在这种情况下，在package.json中添加以下决议项:

  "resolutions": {
    "node-gyp": "8.0.0"
  }

之后，确保安装了Python 3和Visual Studio 2017构建工具和/或Visual Studio 2019构建工具。你也可以执行npm config delete msvs_version命令让node-gyp自动检测你的VS版本。

测试:

Windows 10 Pro Build 19042.985 node . js v15.14.0 npm v7.7.6 Node-gyp -v v3.8.0。

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。
