1. 升级PostgreSQL
最近PostgreSQL更新到了10,于是将原来的9.6进行升级。
brew upgrade postgresql
2. 升级Python3
电脑中的Python版本为3.6.1,于是也尝试升级到最新的3.6.3。
brew upgrade python3
3. 在命令行中使用python3
升级Python后,原先的在命令行中使用Python3.6的命令python3
失效,需要修改配置。
3.1. 打开.bash_profile文件
终端输入:
open ~/.bash_profile
3.2. 编辑bash_profile文件内容
PATH="/usr/local/Cellar/python3/3.6.3/Frameworks/Python.framework/Versions/3.6/bin:${PATH}"
export PATH
#添加别名
Alias python3="/usr/local/Cellar/python3/3.6.3/Frameworks/Python.framework/Versions/3.6/bin/python3.6"
3.3. 重新读取.bash_profile文件
终端输入:
source .bash_profile
4. 替换brew源
官方源下载速度实在太慢,可以替换成中科大或清华的镜像:
4.1. 中科大镜像
替换brew.git,终端输入:
cd "$(brew --repo)"
git remote set-url origin https://mirrors.ustc.edu.cn/brew.git
替换homebrew-core.git,终端输入:
cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core"
git remote set-url origin https://mirrors.ustc.edu.cn/homebrew-core.git
4.2. 清华镜像:
cd "$(brew --repo)"
git remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/brew.git
cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core"
git remote set-url origin https://mirrors.tuna.tsinghua.edu.cn/git/homebrew/homebrew-core.git
brew update
替换Homebrew-bottles:
open ~/.bash_profile
加入:
export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.tuna.tsinghua.edu.cn/homebrew-bottles
保存
source .bash_profile
4.3. 还原官方源:
重置brew.git:
cd "$(brew --repo)"
git remote set-url origin https://github.com/Homebrew/brew.git
重置homebrew-core.git:
cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core"
git remote set-url origin https://github.com/Homebrew/homebrew-core.git
