Question

当我执行npm run start时突然出现了这个错误。该项目采用ant-design pro构建。可悲的是，它没有告诉我错误在哪里。你能帮我找到错误或修复它吗？构建只停留在91％，然后我收到错误消息。

这是错误：

编辑：我还将我的npm更新为版本6但仍然收到相同的错误消息。请指教。

好吧，我一直在寻找，现在我发现了一个问题，帮助了我。基本上，将此代码添加到我的package.json是帮助我的。

"start": "HARD_SOURCE=none npm run _start", "_start": "cross-env ESLINT=none roadhog dev",

我无法理解为什么用中文写的，无论如何，这里是github问题的链接，因为它可能会帮助你们中的一些人理解错误。 antdesign github issue fixed here

Answer 2

可能是因为 localhost 没有用系统“主机” 文件中的必需语法定义。该文件可以位于@：

linux

etc/hosts

Windows

c:\ **Windows** \System32\Drivers\ **etc** \ **hosts**

即文件输入错误。

因此，请尝试使用下面的文本替换该文件中的所有内容，因为这是 hosts 文件中总是可以正常使用的默认文本：

127.0.0.1   localhost

255.255.255.255 broadcasthost

::1             localhost

fe80::1%lo0 localhost

在npm运行开始后，构建卡住了91％
