推荐答案

sudo 启动一个不包含环境变量的新子 shell.
rvmsudo 传递 RVM 设置的任何环境变量，以使您获得正确的 Ruby.这包括 $PATH 以及 $GEM_HOME、$GEM_PATH 和 $BUNDLE_PATH 变量.

sudo starts a new subshell that does not contain environment variables.
rvmsudo passes on any environment variables that RVM set up to get you to the correct Ruby. This includes the $PATH as well has $GEM_HOME, $GEM_PATH and $BUNDLE_PATH variables.
