Python 2.7 在Python2.7中仍然可以使用pipenv吗？

我用pipenv在我的计算机上安装了Python2.7和Python3.8。我通过运行以下命令创建了一个2.7项目：

pipenv --two install
pipenv shell
> python --version
> > Python 2.7.15

但当我尝试使用pipenv安装新的Dependency时，由于SNIMissingWarning，我遇到了一个TLS错误：

pip install pylint
...
[pipenv.exceptions.InstallError]: ['Collecting astroid==1.6.6 (from -r C:\\Users\\aymeric\\AppData\\Local\\Temp\\pipenv-pktqf1dv-requirements\\pipenv-66rq3_4k-requirement.txt (line 1))', "  Could not fetch URL https://pypi.org/simple/astroid/: There was a problem confirming the ssl certificate: HTTPSConnectionPool(host='pypi.org', port=443): Max retries exceeded with url: /simple/astroid/ (Caused by SSLError(SSLError(1, '_ssl.c:499: error:1407742E:SSL routines:SSL23_GET_SERVER_HELLO:tlsv1 alert protocol version'),)) - skipping"]

This may cause the server to present an incorrect TLS certificate, which can cause validation failures. 
You can upgrade to a newer version of Python to solve this.

This prevents urllib3 from configuring SSL appropriately and may cause certain SSL connections to fail.

这很奇怪，因为SNIMissingWarning应该是2.7.9中的补丁，如中所述

如果现在无法从2.7 virtualenv访问远程存储库，您该怎么办？

问题是

SSLError（1'”\u ssl.c:499:error:1407742E:ssl例程：SSL23\u GET\u SERVER\u HELLO:tlsv1警报协议版本“）

，这意味着pip试图使用不兼容的TLS版本连接到PyPI。谢谢，但对我来说，潜在的错误是：

SNIMissingWarning:HTTPS请求已发出，但SNI（服务器名称指示）TLS扩展在此平台上不可用。这可能会导致服务器提供不正确的TLS证书，这可能会导致验证失败。
