homebrew安装和解决brew安装速度慢的问题

Posted by Nick Xu

homebrew安装

ruby -e “$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)”

解决brew安装速度慢的问题(替换homebrew镜像源)

1.替换brew.git:

cd $(brew --repo)
git remote set-url origin https://mirrors.aliyun.com/homebrew/brew.git

2.替换homebrew-core.git:

cd $(brew --repo)/Library/Taps/homebrew/homebrew-core
git remote set-url origin https://mirrors.aliyun.com/homebrew/homebrew-core.git

3.终端输入命令:

echo $SHELL 看输出结果是/bin/zsh还是/bin/bash

  • /bin/zsh替换homebrew-bottles:
echo 'export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.aliyun.com/homebrew/homebrew-bottles' >> ~/.zshrc
source ~/.zshrc
  • /bin/bash替换homebrew-bottles:
echo 'export HOMEBREW_BOTTLE_DOMAIN=https://mirrors.ustc.edu.cn/homebrew-bottles' >> ~/.bash_profile
source ~/.bash_profile

4.恢复homebrew国内镜像源配置

  • 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
  • 重置homebrew-bottles
将刚添加到~/.bash_profile文件的语句注释掉即可

解决brew安装包一直卡在Updating Homebrew

运行命令brew install node,结果界面一直卡在Updating Homebrew上,有两种解决办法

方法一:关闭brew每次执行命令时的自动更新(推荐)

vim ~/.bash_profile
# 新增一行
export HOMEBREW_NO_AUTO_UPDATE=true

方法二(懒人方法):

出现Updating Homebrew的时候ctrl+c一下就行

pip下载库超时Connection to files.pythonhosted.org timed out问题解决(换源)

Posted by Nick Xu

1、国内镜像大全

阿里云 http://mirrors.aliyun.com/pypi/simple/
中国科技大学 https://pypi.mirrors.ustc.edu.cn/simple/
豆瓣(douban) http://pypi.douban.com/simple/
清华大学 https://pypi.tuna.tsinghua.edu.cn/simple/
中国科学技术大学 http://pypi.mirrors.ustc.edu.cn/simple/

2、换源命令

临时:pip命令+ -i  +镜像地址。例如 pip install numpy -i https://mirrors.aliyun.com/pypi/simple/

永久:在更新到最新版本pip后,pip config set global.index-url+国内镜像地址,例如

pip config set global.index-url https://mirrors.aliyun.com/pypi/simple/
