通过 pip3 dynaconf 安装期间的异常

如何解决通过 pip3 dynaconf 安装期间的异常

我正在尝试在 Ubuntu VM 上安装特定的 dynaconf 版本，但我需要安装 ara 客户端（Ansible Record Analyzer），但我不断收到这些异常：

user@machine:~$ pip3 install dynaconf==3.1.2
Collecting dynaconf==3.1.2

我尝试升级 steup 工具，但仍然有相同的异常：

我的python版本是：

Python 3.6.9

我的操作系统版本是：

NAME="Ubuntu"
VERSION="18.04.3 LTS (Bionic Beaver)"
ID=ubuntu
ID_LIKE=debian
PRETTY_NAME="Ubuntu 18.04.3 LTS"
VERSION_ID="18.04"

非常欢迎任何建议或提示。

解决方法

我看到您在 3 月 18 日打开了此问题，而就在当天 PIPY 遇到了一些问题，所以看起来这是一个一次性问题，您能否确认现在是否已解决？

,

结果是我使用的代理导致了这个问题，所以我的想法是要么取消设置代理来安装它，要么使用--proxy=[proxy_IP]属性进行安装
