# 安杰云 PyPI Private Source Configuration

PyPI is the official repository of third-party libraries in Python.

To address the issues of limited access speed, restricted concurrent requests, frequent packet loss, and timeouts when accessing the default official source in China, 安杰云's PyPI private source offers pure intranet access. On 安杰云 cloud hosts, you can obtain the required Python Package without an external IP address.

## Global Configuration
Configure the following content in the ~/.pip/pip.conf file:

``` 
[global]
index-url = https://pypi.internal-mirrors.cachecenter.com/simple
``` 

## Specified Source for Installing Python Package

``` 
pip3 install flask -i https://pypi.internal-mirrors.cachecenter.com/simple
```
