最近，我尝试对自己的路径进行一些更改。.bash_profile.
在尝试使用source .bash_profileand get验证了这些更改之后-bash: : command not found，
我还注意到，当我打开外壳程序时，在执行任何命令之前，它的位置已经是“ -bash :: command not找到”。
显然，系统没有考虑对.bash_profile所做的更改。
请帮助！我想我对.bash_profile太搞砸了，不知道如何解决...
.bash_profile的内容：
cat .bash_profile

export PATH=/opt/local/bin:/opt/local/sbin:$PATH

编辑+ bash版本：
echo $BASH_VERSION
3.2.51(1)-release
usr:~ usrname$ source ./.bash_profile
-bash: : command not found
将set -x添加到.bash_profile后，编辑+：
usr:~ usrname$ source ./.bash_profile
++ $'\016'
-bash: : command not found
++ update_terminal_cwd
++ local 'SEARCH= '
++ local REPLACE=%20
++ local PWD_URL=file://usr.local/Users/usrname
++ printf '\e]7;%s\a' file://usr.local/Users/usrname
这行：
export PATH= /Users/usrname/TreeTagger/bin:$PATH
是问题。在变量分配（包括中）中export，不能有空格=。使用添加的空间，它将设置$PATH为空字符串。
更改为：
export PATH=/Users/usrname/TreeTagger/bin:$PATH
为了安全起见，您应该添加双引号：
export PATH="/Users/usrname/TreeTagger/bin:$PATH"
以防万一值中有任何特殊字符$PATH。
您也有同样的问题UIMA_HOME。
更新 ：
根据以后的评论，您似乎在中有一个杂散控制字符.bash_profile。随着set -x它的显示$'\016'。bash尝试将其视为命令名称，并不奇怪地找不到它。编辑您的.bash_profile字符并删除该字符。
（无论如何，其他错误都需要纠正。）
