"bash : command not found" error
提问by ibadukefan
I am trying to setup my machine for development and I keep getting the error, -bash: command not found. I am getting while running various commands. I am brand new to this, trying to get into development, and am not sure how to fix it. From what I have read it may have something to do with my PATH. Again, I'm new to this so I really have no clue.
我正在尝试设置我的机器进行开发，但我不断收到错误，-bash: command not found. 我在运行各种命令时遇到了问题。我对此很陌生，正在尝试进行开发，但不知道如何解决。从我读过的内容来看，它可能与我的路径有关。同样，我是新手，所以我真的不知道。
new-host:~ Home$ echo $PATH

I didn't have a bash profile. So I created one and voila, no more errors. Thanks again fellas for trying to help a noob!
我没有 bash 个人资料。所以我创建了一个，瞧，没有更多的错误。再次感谢小伙子们试图帮助菜鸟！

On OS X, by default, bash should be located as /bin/bash. So if /bin is not in your path then you need to put it there. It sounds like you must have been tweaking the base OS X install considerably. That, or you have installed some packages (macports, fink, brew, etc.???) that have 'adjusted' your path variable, perhaps in undesirable ways.
在 OS X 上，默认情况下，bash 应位于/bin/bash. 所以如果 /bin 不在你的路径中，那么你需要把它放在那里。听起来您一定对基本的 OS X 安装进行了相当大的调整。那，或者您安装了一些软件包（macports、fink、brew 等），它们可能以不受欢迎的方式“调整”了您的路径变量。
If you can execute /bin/bash, then you just need to make /bin an entry in your PATH environment variable again. Places to check:
如果您可以执行 /bin/bash，那么您只需要再次将 /bin 设为 PATH 环境变量中的一个条目。检查的地方：
/etc/profile
/etc/bashrc
~/.profile
~/.bashrc

Your only problem is bad typing. You get the error -bash: XXX: command not foundwhen you type something on the command line that isn't a built-in shell function or external executable program in your path. You got -bash: dvm: command not foundwhen you tried to run rvmbecause you typed dvminstead.
你唯一的问题是打字不好。-bash: XXX: command not found当您在命令行上输入的不是内置 shell 函数或路径中的外部可执行程序时，您会收到错误消息。-bash: dvm: command not found当你试图运行时，你得到了，rvm因为你输入了dvm。
Your $PATHis fine, as /binis right in there in the middle, so there's no problem with /bin/bashbeing found.
你$PATH的很好，/bin就在中间，所以/bin/bash被发现没有问题。
In order to see what the contents of /etc/profileor ~/.bashrcare, you can't just type their names, like you were doing in the comments to Randy Howard's question, you have to use a command like cat /etc/profileto list its contents.
为了查看/etc/profile或的内容~/.bashrc，您不能像在对 Randy Howard 问题的评论中所做的那样只输入它们的名称，您必须使用命令 likecat /etc/profile列出其内容。
