Question

似乎无法想出这个，试图运行任何脚本我得到这个错误：
invalid byte sequence in UTF-8 (ArgumentError)

我有一台新的OS X机器，一切都很新鲜，使用Ruby 1.9.3和Rails 3.2.1，我已经开发了几天没有问题。

我今天离开了几个小时，现在我无法运行任何脚本。

我第一次尝试新迁移时遇到错误，认为这是Postgres的问题，重新安装，确保所有表都使用UTF-8进行编码。

我还重新安装了RVM和Rails。

我认为如果它与数据库有关，调试会更容易，但是我创建了新的应用程序，甚至无法启动服务器，收到同样的错误。

现在我看的越多，显然有一些东西搞砸了postgresql，因为在postgresql上的应用程序中，bundle失败了安装pg

An error occured while installing pg (0.12.2), and Bundler cannot continue.
Make sure that `gem install pg -v '0.12.2'` succeeds before bundling.

它提到检查的mkmf.log文件是空白的。

所以我猜测Postgresql可能是这个问题的根源，但我很难理解为什么使用sqlite3的新应用程序仍会抛出此字节错误。

任何帮助都将不胜感激，如果我能提供更多信息，请告诉我。

修改

这个问题似乎已经解决了。

我制作的机器的唯一变化是@Frederick Cheung建议的;我从我的Path中删除了一个sbin文件夹，该文件夹来自已卸载的旧NGINX安装。

可能这是差异，但对我来说似乎不太可能。

无论如何，我跑了一个命令，一切都很好，已经好几天了。

Answer 1

根据堆栈跟踪判断，PATH环境变量包含一些令人讨厌的数据。我首先检查它并删除看起来不属于它的任何东西

Answer 2

您的任何初始化程序或环境配置（application.rb，development.rb等）是否包含无效字符？

如果您从网上抓取了一个javascript文件，并且标题中有时髦的字符，通常会发生这种情况。如果将它包含在application.js中，则Sprockets解析器会对其进行抖动。

在这种情况下，看起来就像是在尝试运行你的应用程序时，所以它告诉我在初始化过程中使用的其中一个文件中是无效字符。

Rails无效字节运行任何脚本
