python-3.x - 无法使用 pip3 安装 DjangoRestFramework？

Question

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/

  Retrying (Retry(total=0, 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/
  Could not find a version that satisfies the requirement djangorestframework (from versions: )
No matching distribution found for 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，我被允许自由安装和卸载。

pip3 搜索也会抛出相同的 SSL 错误，然后将其吐给我:

检查 DRF 的要求.

Requirements

REST framework requires the following:

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

We highly recommend and only officially support the latest patch release of each Python and Django series.
