bash - 获取-bash : mvn: command not found

Question

我尝试在 .profile 文件中设置 Maven PATH，并在终端 (Mac OSX) 中使用导出命令。但是，在运行 mvn 命令时，得到 -bash: mvn: command not found

请帮忙。

你具体设置了什么？您是否像这样设置 PATH(或类似的东西):

export PATH=$PATH:...:$M2_HOME/bin

如果是，您是否注销并重新登录？根据 bash 联机帮助页:

When bash is invoked as an interactive login shell, or as a non-interactive shell with the --login option, it first reads and executes commands from the file /etc/profile, if that file exists. After reading that file, it looks for ~/.bash_profile, ~/.bash_login, and ~/.profile, in that order, and reads and executes commands from the first one that exists and is readable. The --noprofile option may be used when the shell is started to inhibit this behavior.
...
When an interactive shell that is not a login shell is started, bash reads and executes commands from /etc/bash.bashrc and ~/.bashrc, if these files exist. This may be inhibited by using the --norc option. The --rcfile file option will force bash to read and execute commands from file instead of /etc/bash.bashrc and ~/.bashrc.

如您所见，.profile 中的命令不会针对非登录 shell(登录后打开的 shell 类型)执行。因此，您必须注销/登录或手动获取文件以考虑您的设置。看这个blog post更多细节。
