ruby-on-rails - US-ASCII 中的无效字节序列(ArgumentError)，没有任何帮助

Question

每当我运行 rake db:create 时，我都会突然出现错误。错误是

rake aborted!
/home/me/.rvm/gems/ruby-1.9.3-p392/gems/rake-10.0.4/lib/rake/trace_output.rb:16:in `block in trace_on': invalid byte sequence in US-ASCII (ArgumentError)

  from /home/me/.rvm/gems/ruby-1.9.3-p392/bin/rake:23:in `<main>'

我做了

me@ubuntu:~ export LANG="C.UTF-8"
me@ubuntu:~ export LC_ALL="C.UTF-8"

我得到了

me@ubuntu:~ echo $LANG
en_US
me@ubuntu:~ echo $LC_ALL
en_US.UTF-8

尝试添加字符串作为此任务涉及的文件的第一行:

#encoding: utf-8

这些文件可能是您所有的自定义初始化程序、您的 database.yml 等
