我正在尝试从源代码构建JHipster Registry，因为我正在关注Matt Raible's tutorial。
但是我收到退出代码1的错误，以下是生成的堆栈跟踪。

已执行的步骤：
1）从Github下载JHipster Registry作为拉链并解压缩。
2）导航到Windows PowerShell中的该目录，然后运行yarn或yarn install。
我是JHipster的新手。我不确定问题是sass还是python2或其他问题。我正在寻找有关该问题以及如何解决问题的详细信息？

[据我所知，
i）使用fsevents警告是因为我使用的是Windows x-64，而fsevents主要用于Mac来监控文件系统。这是对的吗？
ii）注册表是否使用Angular 2作为前端设计？ （即使您可以使用JHispter构建Angular 4应用程序）
iii）构建新包时，node_sass会抱怨它找不到python.exe文件，但我检查了文件夹，但该文件存在。我也在路径中有python3.5.4。
在后续步骤中，它是否正在寻找python2，因为它没有找到python3？如果JHipster是一个SpirngBoot（后端）+ Angular（前端）应用程序，那么python将在哪里使用？我们也可以编写温和的python脚本吗？]
答案 0 :(得分：0)
i）纠正你可以忽略这个警告
ii）注册表是由JHipster生成的应用程序（您可以在.yo-rc.json文件中查看其选项）并使用角度4作为其UI
iii）python仅用于构建节点而不是app运行时，这里的问题是node-sass无法构建，这是一个环境问题：
现在，坏消息是你在Windows上; nodejs的最佳平台是Linux和macOS，Matt Raible在macOS上，所以他没有遇到你所有的问题。即使修复python和nodejs版本node-gyp也可能无法构建本机模块。如果发生这种情况，你几乎没有其他选择：

我只是将NodeJS降级到6.x，事情开始变得很有效。所以，请尝试降级它并使用：yarn。重新编译。
