出于某种原因,当我运行`brew link python时,它没有符号链接.我收到了以下错误,我做了它告诉我要做的事情,但它不起作用.我已经尝试过做它告诉我要做的事情,但也许我没有把formula_name放在正确的位置.此外,当我做'哪个python'它没有指向Homebrew python,我也需要帮助修复它.
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/smtpd.py
Target /usr/local/bin/smtpd2.py already exists. You may need to delete it.
To force the link and delete this file, do:
brew link --overwrite formula_name
在经历了sqlite3的这个冲泡问题之后,我做到了
brew rm sqlite python python3
然后
brew install python python3
这安装python2.7.5作为默认解释器和brew安装pip以及python,我以为我能够
pip install virtualenv
为新的python2.7.5安装virtualenv.但是,我得到了
-bash: /usr/local/share/python/pip: /usr/local/Cellar/python/2.7.3/bin/python: bad interpreter: No such file or directory
我怎样才能解决这个问题？我应该在之间创建一个符号链接
/usr/local/share/python/pip --> /usr/local/Cellar/python/2.7.5/bin/pip-2.7
我刚刚使用brew在OS X上安装Python 3.该python3命令现在使用brew Python 3.6启动解释器,但python仍然使用默认系统Python 2.7打开解释器.
我的理解是,默认情况下,brew Python现在应该覆盖系统Python.(即,在$ PATH中查看/ usr/bin和/ usr/local/bin的顺序等).在我的PATH中,/ usr/local/bin位于/ usr/bin之前,因此它不应该是PATH问题.我试过重启终端,没有任何效果.
如果相关,这是我的完整PATH.
/Users/**/.rvm/gems/ruby-1.9.3-p362/bin:/Users/**/.rvm/gems/ruby-1.9.3-p362@global/bin:/Users/**/.rvm/rubies/ruby-1.9.3-p362/bin:/Users/**/.rvm/bin:/Users/**/.rvm/bin:/Users/**/Python/PmagPy/programs/conversion_scripts2/:/Users/**/Python/PmagPy/programs/conversion_scripts/:/Users/**/Python/PmagPy/programs:/usr/local/heroku/bin:./bin:/usr/local/sbin:/usr/local/bin:/usr/local/share/npm/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Library/TeX/texbin:/opt/X11/bin
为什么brew不优先使用？我该如何修复(或排除故障)？如果我找不到另一个选项,我可以创建一个别名,但我更愿意了解正在发生的事情并找到问题的根源.
更新:
我检查了"可能重复"的问题,但我的问题似乎不是一个链接问题:
~ brew link --overwrite --dry-run python
Warning: Already linked: /usr/local/Cellar/python/3.6.4_4
To relink: brew unlink python && brew link python
