Question

最近我尝试对.bash_profile.中的路径进行一些更改在我尝试使用source .bash_profile验证这些更改并获得-bash: : command not found之后，我也注意到当我打开shell时，在执行任何命令之前，它已经存在了＃34; -bash ::找不到命令＆＃34; ...
显然，系统没有考虑对.bash_profile所做的更改...... 请帮忙！我想我过多地混淆了.bash_profile，不知道如何修复它......

.bash_profile的内容：

cat .bash_profile
# Finished adapting your PATH environment variable for use with MacPorts.
export PATH=/opt/local/bin:/opt/local/sbin:$PATH
##
# MacPorts Installer addition on 2014-03-24_at_12:05:55: adding an appropriate PATH variable for use with MacPorts.
### Your previous /Users/usrname/.bash_profile file was backed up as /Users/usrname/.bash_profile.macports-saved_2014-03-24_at_12:05:55
##export PATH="/Users/usrname/anaconda/bin:$PATH"
# added by Anaconda 1.9.1 installer
##Additional binary folders
export PATH=/Users/usrname/TreeTagger/cmd:$PATH
export PATH= /Users/usrname/TreeTagger/bin:$PATH
export UIMA_HOME= $/Users/usrname/apache-uima
export PATH=$PATH:$UIMA_HOME/bin
export HEIDELTIME_HOME='/Users/usrname/Downloads/heideltime-kit/'
export TREETAGGER_HOME='/Users/usrname/TreeTagger'
source $HEIDELTIME_HOME/metadata/setenv

更新了.bash_profile的内容：

cat .bash_profile
# Finished adapting your PATH environment variable for use with MacPorts.
export PATH=/opt/local/bin:/opt/local/sbin:$PATH
##
# MacPorts Installer addition on 2014-03-24_at_12:05:55: adding an appropriate PATH variable for use with MacPorts.
### Your previous /Users/usrname/.bash_profile file was backed up as /Users/usrname/.bash_profile.macports-saved_2014-03-24_at_12:05:55
##export PATH="/Users/usrname/anaconda/bin:$PATH"
# added by Anaconda 1.9.1 installer
##Additional binary folders
export PATH="/Users/usrname/TreeTagger/cmd:$PATH"
export PATH="/Users/usrname/TreeTagger/bin:$PATH"
export UIMA_HOME="/Users/usrname/apache-uima"
export PATH=$PATH:$UIMA_HOME/bin
export HEIDELTIME_HOME="/Users/usrname/Downloads/heideltime-kit/"
export TREETAGGER_HOME="/Users/usrname/TreeTagger"
source $HEIDELTIME_HOME/metadata/setenv

最后引用后的完整shell输出＆＃39;校正：

使用echo命令编辑：

  cat .bash_profile

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

export TREETAGGER_HOME="/Users/usrname/TreeTagger"
echo before
source $HEIDELTIME_HOME/metadata/setenv
echo after


usr:~ usrname$ source .bash_profile
-bash: : command not found
usr:~ usrname$ echo $PATH
/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/opt/X11/bin

编辑+ bash版本：

echo $BASH_VERSION
3.2.51(1)-release
usr:~ usrname$ source ./.bash_profile
-bash: : command not found

编辑+后，将-x添加到.bash_profile：

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

Answer 1

这一行：

export PATH= /Users/usrname/TreeTagger/bin:$PATH

是问题所在。在包含export的变量分配中，=周围不能有空格。通过添加空格，它将$PATH设置为空字符串。

将其更改为：

export PATH=/Users/usrname/TreeTagger/bin:$PATH

为安全起见，您应该添加双引号：

export PATH="/Users/usrname/TreeTagger/bin:$PATH"

以防$PATH。

的值中有任何特殊字符

UIMA_HOME存在同样的问题。

更新：

根据以后的评论，您的.bash_profile似乎有一个迷路控制角色。 set -x显示为$'\016'。 bash尝试将其视为命令名称，并且不会令人惊讶地无法找到它。修改您的.bash_profile并删除该字符。

（无论如何都需要纠正其他错误。）
