ruby-on-rails - gem 更新: unable to convert "\xE7" to UTF-8 in conversion from ASCII-8BIT to UTF-8 to US-ASCII

Question

刚刚在一台已经有一段时间没有更新的轻度使用服务器计算机上运行了gem update...并且收到大量“无法转换“\x??”的信息从 ASCII-8BIT 到 UTF-8 到 US-ASCII 的转换为 UTF-8 错误...”。其中包括来自控制台的异常(exception)。有人知道发生了什么吗？

我在 Mac OS X 上使用 iTerm2 而不是默认的 OS X Terminal.app 时遇到了类似的问题。iTerm2 未正确设置 LC_CTYPE，一旦我将 export LC_CTYPE="utf-8" 添加到 ~/.bash_profile，gem 安装就会顺利进行。

注意:当然，您可以将导出添加到任何其他profile 文件
