pip 使用国内镜像源

使用pip install 的时候总是出现read timeout 之类的错误

使用国内镜像 https://pypi.tuna.tsinghua.edu.cn/simple
例如我要安装 scrapy

pip install -i https://pypi.tuna.tsinghua.edu.cn/simple scrapy

添加源的配置

Linux下,修改 ~/.pip/pip.conf (没有就创建一个), 修改 index-url至tuna,内容如下:

[global]
index-url = https://pypi.tuna.tsinghua.edu.cn/simple

windows下,直接在user目录中创建一个pip目录,如:C:\Users\xx\pip,新建文件pip.ini,内容如下

[global]
index-url = https://pypi.tuna.tsinghua.edu.cn/simple

pip install 出错

$ pip install pycairo

You are using pip version 10.0.1, however version 20.2.2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

用brew安装pkg-config

 $ brew install pkg-config

######################################################################## 100.0%

🍺  /usr/local/Cellar/pkg-config/0.29.2_3: 11 files, 623.6KB

然后再运行pip install pycairo。 出现错误

执行brew install cairo pkg-config freetype harfbuzz,把这几个包安装一下。 然后再pip install pycairo,安装成功。
