卸载完dmp文件安装的python3后,我们需要重新安装当前稳定版的python3(python 3.6.4)
brew install python3
此时,安装完成后会出现一点问题:
liyang@liyang ~ brew install python3 Updating Homebrew... ==> Auto-updated Homebrew! Updated 1 tap (homebrew/php). ==> Updated Formulae homebrew/php/adminer homebrew/php/drupalconsole ==> Installing dependencies for python3: gdbm ==> Installing python3 dependency: gdbm ==> Downloading https://mirrors.tuna.tsinghua.edu.cn/homebrew-bottles/bottles/gd ######################################################################## 100.0% ==> Pouring gdbm-1.14.1_1.high_sierra.bottle.tar.gz 🍺 /usr/local/Cellar/gdbm/1.14.1_1: 20 files, 555.7KB ==> Installing python3 ==> Downloading https://mirrors.tuna.tsinghua.edu.cn/homebrew-bottles/bottles/py ######################################################################## 100.0% ==> Pouring python3-3.6.4_2.high_sierra.bottle.tar.gz Error: An unexpected error occurred during the `brew link` step The formula built, but is not symlinked into /usr/local Permission denied @ dir_s_mkdir - /usr/local/Frameworks Error: Permission denied @ dir_s_mkdir - /usr/local/Frameworks ✘ liyang@liyang ~ ls /usr/local/Frameworks ls: /usr/local/Frameworks: No such file or directory
此时会发现两个错误,第一个是权限问题,第二个是/usr/local/Frameworks目录不存在。
首先,我们先解决目录不存在的问题
sudo mkdir /usr/local/Frameworks
创建目录以后,我们开始解决权限问题,通过Google,发现大多数处理方法都是
sudo chown $(whoami):admin /usr/local/
虽然能解决问题,但并不是一个好的idea~,这里非常不建议使用,那么解决方案入下:
sudo chown -R $(whoami) $(brew --prefix)/*
此时,上面两个问题就已经安装完成,只需要最后一步link一下即可。
brew link python3 Linking /usr/local/Cellar/python3/3.6.4_2... 1 symlinks created
此时python3就已经安装完成(/usr/local/Cellar/),以后可以使用brew来更新了~
