bundle install error“US-ASCII（ArgumentError）中的无效字节序列”
当我尝试运行’bundle install’时，我得到一个奇怪的错误：“US-ASCII（ArgumentError）中的无效字节序列”
$ bundle install Updating git://github.com/devton/catarse_paypal_express.git Unfortunately, a fatal error has occurred.

if RUBY_VERSION =~ /1.9/ Encoding.default_external = Encoding::UTF_8 Encoding.default_internal = Encoding::UTF_8 end
但我认为后来它会导致不同的错误，所以我宁愿不使用它，只是试着去理解这里真正的错误。 我确信这个相同的代码适用于不同的系统……
作为解决方法，您可以在系统中设置utf8语言环境：
export LANG="C.UTF-8" export LC_ALL="C.UTF-8"
