' ': 命令未找到 - .bashrc/.bash_profile [英] ' ': command not found - .bashrc / .bash_profile

问题描述

我有 Windows，使用 Cygwin，试图通过我的 .bashrc 文件永久设置 JAVA_HOME.

I have windows, using Cygwin, trying to set JAVA_HOME permanently through my .bashrc file.

.bashrc:

export PATH="$JAVA_HOME/bin:$PATH"  
export JAVA_HOME=$JAVA_HOME:"/cygdrive/c/Program Files (x86)/Java/jdk1.7.0_05"

.bash_profile:

if [ -f ~/.bashrc ]; then
   source ~/.bashrc
fi

运行 cygwin:

-bash: $'377376if': command not found
-bash: $'then
': command not found
: No such file or directorysu//.bashrc
-bash: /cygdrive/c/Users/jhsu//.bash_profile: line 3: syntax error near unexpected token `fi'
-bash: /cygdrive/c/Users/jhsu//.bash_profile: line 3: `fi'

我不确定我是否从适用于另一个系统的教程中获取了命令，或者我是否遗漏了一个步骤.或者空格导致我的命令无法正常运行.

I am not sure if I took the commands from a tutorial that was meant for another system or if I am missing a step. Or whitespace is causing my commands not to run properly.

我已经查看了多个类似的问题，但我还没有找到一个与我的问题完全相同的问题.

I've looked at multiple similar questions but I haven't found one where the question has my error exactly.

我的家乡:

$ echo $HOME
/cygdrive/c/Users/jhsu
$ echo ~
/cygdrive/c/Users/jhsu/

所以我认为文件应该放在正确的位置.

So I believe the files should be placed in the correct spot.

推荐答案

当 Cygwin 中的所有其他方法都失败时...

尝试对相关文件运行 dos2unix 命令.

Try running the dos2unix command on the file in question.

当您看到如下错误消息时可能会有所帮助:

It might help when you see error messages like this:

-bash: ' ': 命令未找到

Windows 样式的换行符可能会导致 Cygwin 出现问题.

Windows style newline characters can cause issues in Cygwin.

dos2unix 命令修改换行符，使其与 Unix/Cygwin 兼容.

The dos2unix command modifies newline characters so they are Unix / Cygwin compatible.

注意:dos2unix 命令会就地修改文件，因此在必要时采取预防措施.

CAUTION: the dos2unix command modifies files in place, so take precaution if necessary.

如果需要保留原文件，请先备份.

If you need to keep the original file, you should back it up first.

Mac 用户注意:dos2unix 命令在 Mac OS X 上不存在.

Note for Mac users: The dos2unix command does not exist on Mac OS X.

还有一个 unix2dos 命令可以执行相反的操作:

There is also a unix2dos command that does the reverse:

它修改了 Unix 换行符，以便它们与 Windows 工具兼容.

It modifies Unix newline characters so they're compatible with Windows tools.

如果您用记事本打开一个文件并且所有行都运行在一起，请尝试unix2dos filename.

If you open a file with Notepad and all the lines run together, try unix2dos filename.
