在Windows 10 SQL Server 19中，解决方案是已知的。

复制以下文件:

libssl-1_1-x64.dll libcrypto-1_1-x64.dll

从文件夹中

C:\Program Files\Microsoft SQL Server\MSSSQL15。MSSQLSERVER \ PYTHON_SERVICES \图书馆\ bin

到文件夹

C:\Program Files\Microsoft SQL Server\MSSSQL15。MSSQLSERVER \ PYTHON_SERVICES \ dll

然后打开一个新的DOS命令shell提示符。

对于OpenSUSE，以同样的方式，但对上面列出的包做了一些更改:

zypper install zlib-devel libopenssl-devel ncurses-devel sqlite3-devel readline-devel tk-devel gdbm-devel libpcap-devel xz-devel

然后cd到Python源代码dir和

make
make install

or

make
make altinstall

也许

ln -s /usr/local/lib64/python3.6/lib-dynload/ /usr/local/lib/python3.6/lib-dynload

应该为OpenSUSE用户执行。请参见Python 3.7安装无法在openSUSE Leap 42.3上工作

只要尝试通过Anaconda提示安装即可

苹果操作系统

我在Mac OS(Mojave)上遇到了同样的问题，并解决了这个链接中提到的问题- Openssl问题。

如果你没有Homebrew或不知道什么是Homebrew:

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

或者如果你已经安装了Homebrew:

brew update && brew upgrade
brew uninstall --ignore-dependencies openssl; brew install https://github.com/tebelorg/Tump/releases/download/v1.0.0/openssl.rb

更新: 请记住，我必须使用——ignore-dependencies标记，因为安装的其他包依赖于OpenSSL。

另外，如果问题是在使用pyenv后引起的，您可以通过使用以下方法修复:

brew reinstall python

目前在Windows 10上的Anaconda提示符(Anaconda3)也有同样的问题。这里是解决方案:https://github.com/ContinuumIO/anaconda-issues/issues/10576

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/

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
