Rails不能要求＆＃39; nokogiri / nokogiri＆＃39 ;,尽管IRB可以

标签： ruby-on-rails rubygems nokogiri

首先，尽管我们几乎完全相同的标题，this post并没有解决这个问题。

两天前我在开发模式下运行rails，一切都很好。今天我启动服务器，遇到以下错误：

ooo = one()
ooo.start()

Process Loop
Thread Loop
{'hi': 1}
Process Loop
YES
{'hi': 1}
Process Loop
YES
{'hi': 1}
Process Loop

我总结的意思是当rails调用`require＆＃39; nokogiri / nokogiri＆＃39; rails无法找到gem并且失败了。我的第一个想法是检查，看看我是否有宝石，所以我打电话给

我的下一个想法是重新加载nokogiri，所以我卸载并重新安装了一些，并重新启动我的Mac，但无济于事。

我在网上搜索了一个咒语，而我发现遇到同样问题的最接近的人解决方案是Windows存在兼容性问题。这非常无益，因为我有一台Mac。

现在，我甚至不知道自己不知道什么。为什么这个错误会被解雇？从现在和两天前我的计算机上发生了什么变化来发生此错误？我需要做些什么来解决这个问题？

叹息 我发现了这个问题。如果您将最新项目保留在桌面上，就像我一样，Mac OS会尝试通过将文件上传到云来节省磁盘空间。如果您的应用程序的一半在云中，当您尝试运行本地主机时，您的应用程序的一半将不在那里。我从云端重新下载了文件，它运行得很好。
