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
