在尝试自己编译python后，仍然缺乏ssl模块，我最终尝试从apt安装缺少的模块，就像这样:

安装python3-openssl

对于未来试图解决这个问题的Oracle Linux用户，下面是对我有用的方法。 首先安装缺少的库:

yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel 
readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel

然后cd到Python3。X库并运行:

make
make install 

为我工作。

pkg install openssl

使用此选项可以启用ssl。

对于Debian用户，以下可能会用到:

 sudo apt install libssl-dev libncurses5-dev libsqlite3-dev libreadline-dev libtk8.6 libgdm-dev libdb4o-cil-dev libpcap-dev

然后cd到Python 3. exe文件所在的文件夹。X库源代码，运行:

./configure
make
make install

我得到了同样的错误:

WARNING: pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.
WARNING: Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError("Can't connect to HTTPS URL because the SSL module is not available.")': /simple/pb-tool/
WARNING: Retrying (Retry(total=3, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError("Can't connect to HTTPS URL because the SSL module is not available.")': /simple/pb-tool/
ERROR: Operation cancelled by user
WARNING: pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.
Could not fetch URL https://pypi.org/simple/pip/: There was a problem confirming the ssl certificate: HTTPSConnectionPool(host='pypi.org', port=443): Max retries exceeded with url: /simple/pip/ (Caused by SSLError("Can't connect to HTTPS URL because the SSL module is not available.")) - skipping

在《Anaconda》中，我使用了以下命令:

conda install anaconda-navigator

本文中提到:pip配置了需要TLS/SSL的位置，但是Python中的SSL模块不可用

我试着:

python -m pip install --upgrade pip

在那之后，它在Windows 10中工作得很好。
