brew：macOS 上的 bash 补全功能损坏

我正在使用通过 brew:bash-completion和安装的以下 bash 补全bash-completion@2。我的.bashrc外观如下：

if [ -f /usr/local/share/bash-completion/bash_completion ]; then
. /usr/local/share/bash-completion/bash_completion
fi


if [ -f /usr/local/Cellar/bash-completion/1.3_2/etc/bash_completion ]; then
  BASH_COMPLETION=/usr/local/Cellar/bash-completion/1.3_2/etc/bash_completion
  . /usr/local/Cellar/bash-completion/1.3_2/etc/bash_completion
fi

问题是当我按下TAB键盘时出现错误：

-bash：单词：错误的数组下标

这里有什么问题？我该如何解决？

更新 1：/usr/local/share/bash-completion/bash_completion删除错误后.bashrc不会发生，但我错过了许多完成。

答案1

解决方案是我应该从 1.3.2 之前调用 bash 完成bash-completion@2。以下是我的样子.bashrc，这解决了问题：

if [ -f /usr/local/Cellar/bash-completion/1.3_2/etc/bash_completion ]; then
  BASH_COMPLETION=/usr/local/Cellar/bash-completion/1.3_2/etc/bash_completion
  . /usr/local/Cellar/bash-completion/1.3_2/etc/bash_completion
fi

if [ -f /usr/local/share/bash-completion/bash_completion ]; then
    . /usr/local/share/bash-completion/bash_completion
fi

答案2

新的正确方法是将以下行添加到您的 ~/.bash_profile::

[[ -r "/usr/local/etc/profile.d/bash_completion.sh" ]] && . "/usr/local/etc/profile.d/bash_completion.sh"
