尝试通过自制软件安装python时出现错误。brew说它无法链接python，输出如下：
Linking /usr/local/Cellar/python/2.7.3... Warning: Could not link python. Unlinking... Error: Could not symlink file: /usr/local/Cellar/python/2.7.3/bin/smtpd2.py /usr/local/bin/smtpd2.py may already exist. /usr/local/bin may not be writable.
在/ usr / bin和bin权限上使用ls -la：
The drwxrwxrwx 26 root admin 884 26 Oct 16:03 bin
而且smtpd2.py存在。我该如何解决？删除smtpd2.py吗？
听起来像是/ usr / local的权限问题。
### Makes you owner of /usr/local $ sudo chown -R `whoami` /usr/local ### Force uninstalls failed python $ brew uninstall -f python ### Clear the brew cache $ rm -rf `brew --cache` ### Recreate the brew cache $ mkdir `brew --cache` ### Cleanup - cleans up old homebrew files $ brew cleanup ### Prune - removes dead symlinks in homebrew $ brew prune ### Doctor - runs homebrew checks for common error causing issues $ brew doctor ######## ### Google and follow steps to fix what `brew doctor` came back with ######## ### Reinstall python $ brew install python
