Python 包管理工具 pip

Python 包管理工具 pip

• 有时候使用pip下载程序特慢,可以手动指定镜像源

• [](https://pypi.doubanio.com/simple/)

pip install qiniu
pip install -i https://pypi.doubanio.com/simple/ qiniu

在 PyPI Mirror 查看镜像的活跃度.选择CN地区合适的镜像即可.

具体的配置方法如下

Using a mirror Single Usage:

pip install -i http://<mirror>/simple <package>

Global settings: Add *~/.pip/pip.conf * that includes: 在 ~/.pip/ 下创建文件 pip.conf(如果还没有的话),并填入以下内容:

* [global]
index-url = http://<mirror>/simple

• pip安装python库总是下载超时,有什么解决方法吗?

• [/root/.pip/pip.conf] “`bash

• [global] index-url = http://pypi.douban.com/simple trusted-host = pypi.douban.com

  * [国内pip源提示“not a trusted or secure host”解决方案](https://zhuanlan.zhihu.com/p/21863043)
