Azure DevOps npm install fails with post install script errors for node-sass 4.9.0
我正在尝试 运行 构建。自上次构建 运行（大约 5 个月前）以来，我做了非常小的更改，但现在我无法通过 npm install.

这似乎是编译 Python 代码时的一个错误，但除此之外，我在这里不知所措。任何想法为什么这可能突然开始失败？我能做些什么来修复它吗？
我正在使用 Azure 托管构建
我已经设法解决了这个问题。
出现这个问题似乎是因为构建过程使用了一个叫做 node_gyp 的东西。显然这在节点 11.x 之后停止工作并且节点 12 现在是 Azure DevOps 使用的默认节点（或在撰写本文时）。
我能够通过向管道添加构建步骤来安装节点来纠正问题 8.x - 之后一切正常。
看起来升级 node-sass 也应该修复它（但考虑到项目的年龄，这不是一个理想的解决方案）...
https://github.com/nodejs/node-gyp/issues/1763（link 有关底层 node-gyp 兼容性问题的更多信息）
我正在尝试 运行 构建。自上次构建 运行（大约 5 个月前）以来，我做了非常小的更改，但现在我无法通过 npm install.
这是日志的一些摘录 - 我会 post 更多但不会让我这么大...

这似乎是编译 Python 代码时的一个错误，但除此之外，我在这里不知所措。任何想法为什么这可能突然开始失败？我能做些什么来修复它吗？
我正在使用 Azure 托管构建
我已经设法解决了这个问题。
出现这个问题似乎是因为构建过程使用了一个叫做 node_gyp 的东西。显然这在节点 11.x 之后停止工作并且节点 12 现在是 Azure DevOps 使用的默认节点（或在撰写本文时）。
我能够通过向管道添加构建步骤来安装节点来纠正问题 8.x - 之后一切正常。
看起来升级 node-sass 也应该修复它（但考虑到项目的年龄，这不是一个理想的解决方案）...
