mac下source .bash_profile报/usr/local/etc/bash_completion错误处理
1.背景
在配置java环境变量之后，执行source .bash_profile命令之后，报出一系列/usr/local/etc/bash_completion的错误如下：
/usr/local/etc/bash_completion:59: command not found: shopt
/usr/local/etc/bash_completion:65: command not found: complete
/usr/local/etc/bash_completion:72: command not found: complete
/usr/local/etc/bash_completion:73: command not found: complete
/usr/local/etc/bash_completion:74: command not found: complete
/usr/local/etc/bash_completion:76: command not found: complete
/usr/local/etc/bash_completion:77: command not found: complete
/usr/local/etc/bash_completion:79: command not found: complete
/usr/local/etc/bash_completion:80: command not found: complete
/usr/local/etc/bash_completion:81: command not found: complete
/usr/local/etc/bash_completion:82: command not found: complete
/usr/local/etc/bash_completion:83: command not found: complete
2.解决办法
原因是.bash_profile多了这么一句
[ -f /usr/local/etc/bash_completion ] && . /usr/local/etc/bash_completion
将其注释掉，再执行source .bash_profile即可
