我从这里安装了python3.7https://tecadmin.net/install-python-3-6-on-centos/当尝试使用/升级/安装pip时，我得到了以下错误：
[cloudera@quickstart Python-3.7.6rc1]$ sudo pip3 install --upgrade
WARNING: pip is configured with locations that require TLS/SSL,
however the ssl module in Python is not available.
ERROR: You must give at least one requirement to install (see "pip

希望这有帮助：(
您可能缺少python的一些基本需求。尝试使用安装所有sudo apt-get install libreadline-gplv2-dev libncursesw5-dev libssl-dev libsqlite3-dev tk-dev libgdbm-dev libc6-dev libbz2-dev
我通过在可执行文件所在的目录中启动pip来解决这个问题。永久性的解决方案是添加所需的bin&将目录脚本化为Path。
别忘了重新启动docker，并确保您可以连接到互联网。
解决方案：
在经历了所有地方之后，我最终卸载了python和vs代码。删除了保存在%AppData%下的所有vs代码、python和pip缓存文件。重新安装的python和vs代码。
成功。
pip是19.0.3，我保持这种方式，因为我认为问题是从我更新到20.3.3时开始的。一旦更新到20.3.3，由于SSL错误，您将无法将其降级。
请尝试安装命令，将受信任的主机添加到pip中，如下所示：
sudo pip3 install --trusted-host pypi.org --trusted-host pypi.python.org --trusted-host files.pythonhosted.org -upgrade pip
