bash_completion 在终端中导致“找不到命令”答案

【问题标题】：bash_completion causing a 'command not found' in terminalbash_completion 在终端中导致“找不到命令”
【发布时间】：2016-02-01 15:18:48
【问题描述】：

我正在使用 bash_completion 来点击选项卡并查看分支名称和目录。这一切都有效。为了连接 bash_completion，我把它放到了我的 bash_profile 中：

if [ -f `brew --prefix`/etc/bash_completion ]; then
    . `brew --prefix`/etc/bash_completion
fi

当我现在启动终端时，我得到：

-bash: @MyNameHERE: command not found

如果我从 bash_profile 中删除第一个 sn-p，这会消失，但是 bash_completion 不起作用。有什么想法吗？

【问题讨论】：

你能用brew doctor的确切输出更新你的问题吗？（如果这会引导您找到解决方案，请将其作为答案发布并接受。）
如果您的问题与您的~/.bash_profile 文件有关，请尝试调试它：将此行插入文件开头：set -xv
@msanford ：没有这样的文件或目录。如果我单独运行 brew --prefix 我会得到 /usr/local
在这里引用（复制+粘贴）你得到的输出。
唯一类似的远程目录是一个名为/usr/local/etc/bash_completion.d 的目录，因此您的if 声明显然是错误的。在该目录中是npm、tmux 和其他几个的符号链接。我怀疑homebrew 已经更新为您的脚本没有考虑到的进一步灵活性......

标签： terminal homebrew .bash-profile bash-completion

【解决方案1】：

这个：

-bash: @MyNameHERE: command not found

告诉你它正在尝试执行命令@MyNameHERE 并且在您的系统中找不到它。

尝试替换：

if [ -f `brew --prefix`/etc/bash_completion ]; then
    . `brew --prefix`/etc/bash_completion
fi

与

brewPrefix=`brew --prefix`
if [ -f "${brewPrefix}/etc/bash_completion" ]; then
    . "${brewPrefix}/etc/bash_completion"
fi

我的猜测是brew --prefix 的返回值中的一些空格会导致这种情况

如果这仍然不起作用，请尝试在brewPrefix 变量中设置完整路径（用# 注释另一行）。 .bash_profile 中的执行有时不像在您通常的终端中执行它那样工作，因为环境变量不同

还要确保 sn-p 位于.bash_profile 的底部

【讨论】：

替换了代码 sn-p ，它就像一个魅力。不需要完整路径。此外，放置在 .bash_profile 的底部——但是当它不在底部时它可以工作。
那么问题是路径中有 99% 的空格 :)
