ruby - ubuntu 上的 `gem install` 给出无效的字节序列错误

Question

我使用 RVM 在 Ubuntu (Debian) 上安装 Ruby。我可以使用 irb 并运行 ruby​​ 脚本。

但是，当我尝试安装任何 gem 时，出现此错误:

ERROR:  While executing gem ... (ArgumentError)
    invalid byte sequence in UTF-8

当我为 gem 使用任何值时也会发生这种情况，例如，gem install garbage。

Ruby 1.9.3 和 2.0 都会发生这种情况。

这是命令 locale 报告的内容:

LANG=en_US.UTF-8
LANGUAGE=en_SG:en
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=en_US.UTF-8

这是痕迹:

Answer 1

在 ~/.gemrc 中启用回溯:

---
backtrace: true

安装并提供跟踪日志。

根据跟踪日志，似乎在安装 ruby​​ 时发生了一些无效的事情。需要自己调试。只需打开文件。 /home/crazybob/.rvm/rubies/ruby-1.9.3-p484/lib/ruby/1.9.1/resolv.rb 在 862 行，在它之前插入行: puts str.encoding 和 puts str.inspect 或类似的东西，以查看引发错误的 String。

同时尝试重新安装 ruby ，或使用 rmv 安装最新版本.
