Python 3.x Can'；是否使用pip3安装Djangorest框架？

我一直在努力

pip3 install djangorestframework

我得到了这个结果：

Collecting djangorestframework
Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError(SSLError(1, '[SSL: UNEXPECTED_MESSAGE] unexpected message (_ssl.c:852)'),)': /simple/djangorestframework/

我正在使用python3，这就是我使用pip3的原因

编辑只是为了进一步澄清。。。这仅在安装和卸载此软件包时发生。我用pytz进行了测试，我可以自由安装和卸载

此外，pip3 search还会抛出相同的SSL错误，然后向我吐露这一点：

检查是否满足以下要求：

要求 REST框架需要以下内容：

Python（3.5,3.6,3.7）Django（1.11,2.0,2.1,2.2）

我们高度评价 建议并仅正式支持每个版本的最新补丁 Python和Django系列

---

我建议您使用django==2.2安装需求。然后，如果您需要Django3及更高版本，请在安装所有其他需求之后再安装它。虽然您将看到依赖项错误，但它将正常工作。

这看起来像是网络问题。您是否能够使用

pip3

安装其他软件包？您使用的是哪个python发行版？我使用的是python 3.6.8和Django 2.2，我还可以安装其他软件包。我刚刚卸载并重新安装了pytz到testPython，python 3.6.8是python版本，但是您是如何安装的？通过

apt

，通过下载它，或者你有

anaconda

…？通过aptI，我正在使用Python 3.6.8和Django 2.2。因此，基于此，我认为它应该仍然工作？它似乎是ssl问题，您无法与PyPi通信。尝试升级您的pip：pip安装--upgrade pip--trusted host pypi.org--trusted host files.pythonhosted.org我在Mac上设置项目时遇到了同样的问题。我已经解决了这个问题：我尝试了这个，但是现在我只有PIP19.3.1，没有pip3。我需要pip3来和python3一起使用，不是吗？不是用venv。只为这个项目运行一个虚拟机，所以我想我会跳过它。
