似乎无法解决这个问题，尝试运行任何脚本我都收到此错误:
UTF-8 中的无效字节序列(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。
我首先在尝试新迁移时遇到错误，并认为这是 Postgres 的问题，重新安装，确保所有表都使用 UTF-8 编码。
我还重新安装了 RVM 和 Rails。
我认为如果它与数据库有关，调试起来会更容易，但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。

Make sure that `gem install pg -v '0.12.2'` succeeds before bundling.
它提到要检查的 mkmf.log 文件是空白的。
所以我猜测 Postgresql 可能是这个问题的根源，但我很困惑为什么使用 sqlite3 的新应用程序仍然会抛出这个字节错误。
如有任何帮助，我们将不胜感激，如果我能提供更多信息，请告诉我。
编辑
问题似乎已经自行解决了。
我对我的机器所做的唯一更改是按照@Frederick Cheung 的建议；我从 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。
可能这就是区别，但对我来说似乎不太可能。
无论如何，我运行了一条命令，一切正常，而且已经好几天了。
最佳答案
根据堆栈跟踪判断，PATH 环境变量包含一些令人讨厌的数据。我会首先检查它并删除任何看起来不属于那里的东西
