我是Linux新手,而且我很难尝试完成这项工作。 我卸载并安装了gcc几次。现在,当我运行gcc --version时,它仍然表示zsh: command not found。已安装GCC,但找不到命令
当我去/usr/local/bin和运行ls -l我找到GCC的多个版本

我跑'酿造医生,我得到下面的输出,
Warning: You have MacPorts or Fink installed:
/opt/local/bin/port
This can cause trouble. You don't have to uninstall them, but you may want to
temporarily move them out of the way, e.g.
sudo mv /opt/local ~/macports
Warning: Your Homebrew is outdated.
You haven't updated for at least 24 hours, this is a long time in brewland!
To update Homebrew, run `brew update`.
Warning: You have unlinked kegs in your Cellar
Leaving kegs unlinked can lead to build-trouble and cause brews that depend on
those kegs to fail to run properly once built. Run `brew link` on these:
gcc48
Warning: You have uncommitted modifications to Homebrew
If this a surprise to you, then you should stash these modifications.
Stashing returns Homebrew to a pristine state but can be undone
should you later need to do so for some reason.
cd /usr/local/Library && git stash && git clean -d -f
Warning: /usr/bin occurs before /usr/local/bin
This means that system-provided programs will be used instead of those
provided by Homebrew. The following tools exist at both paths:
erb
gem
git
git-cvsserver
git-receive-pack
git-shell
git-upload-archive
git-upload-pack
irb
rake
rdoc
ri
ruby
testrb
Consider setting your PATH so that /usr/local/bin
occurs before /usr/bin. Here is a one-liner:
echo export PATH='/usr/local/bin:$PATH' >> ~/.bash_profile
我试图运行echo export PATH='/usr/local/bin:$PATH' >> ~/.bash_profile ,重新启动终端,并再次运行brew doctor,它仍抱怨同样的事情。我完全迷失在这里。有人可以用这个指导我吗?我究竟做错了什么?提前致谢。

你使用'zsh',但修改'.bash_profile'。这可能不适合 –

你可能安装了gcc,但你没有一个名为'gcc'的符号链接指向其中一个执行。选择你想要的gcc版本,并建立一个符号链接。例如'ln/usr/bin/gcc/path/to/cellar/gcc-4.8/gcc' –

我跑了,'ln/usr/bin/gcc /usr/local/Cellar/gcc/4.8.3_1/bin/gcc- 4.8'并且它说'ln:/ usr/bin/gcc:没有这样的文件或目录'。我遍历到'/ usr/bin',并且我无法找到gcc –
