我在Windows Vista上使用rails 3.0.3版和ruby版本1.9.2p136（2010-12-15）。脚本控制台给出了以下错误：

我该怎么办？
答案 0 :(得分：0)
问题是Ruby1.9.2有一些编码问题......你必须检查你的db驱动程序是否没有给出错误..你的服务器是否运行？我建议你使用Ruby187
答案 1 :(得分：0)
我遇到了同样的问题。我花了好几个小时试图修复它，重建ruby等等......对于任何设置LANG =它都失败了。
最后我在代码中发现它是在加载init文件期间，即〜/ .inputrc。
问题计算机中我的$ HOME没有〜/ .inputrc ...我试图创建一个空的...并且......工作了！
请尝试touch ~/.inputrc
答案 2 :(得分：0)
我刚刚遇到了与rails 4.1.1相同的问题，结果发现我的~/.inputrc文件是使用ISO-8859-1编码编码的。将文件转换为UTF-8后，一切正常：
$ iconv --from-code=ISO-8859-1 --to-code=UTF-8 ~/.inputrc >out
$ mv out ~/.inputrc
要检查inputrc文件的编码格式，请使用：
$ file --mime-encoding ~/.inputrc
