ubuntu上的`gem install`给出了无效的字节序列错误

标签： ruby ubuntu debian rvm

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，我收到此错误：

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。

以下是命令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_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=en_US.UTF-8

这是跟踪：

在〜/ .gemrc ：

中启用回溯 
---
backtrace: true

进行安装，并提供跟踪日志。

根据跟踪日志，似乎ruby安装中的某些内容无效。它需要自己调试。只需打开文件即可。 {8}行上的/home/crazybob/.rvm/rubies/ruby-1.9.3-p484/lib/ruby/1.9.1/resolv.rb，在插入行puts str.encoding和puts str.inspect之前，或类似的行，以查看引发错误的String。< / p>

还尝试重新安装，或使用安装最新版本。

我的 /etc/resolv.conf 有一些二进制垃圾，导致了这个问题。不确定，为什么 resolv.conf 有这个数据。
