The problem probably caused by library missing.

Before you install python 3.6, make sure you install all the libraries required for python.

$ sudo apt-get install build-essential checkinstall 
$ sudo apt-get install libreadline-gplv2-dev libncursesw5-dev libssl-dev libsqlite3-dev tk-dev libgdbm-dev libc6-dev libbz2-dev

I had the same issue with python3 8 5 installation on Debian9  I have done a build  but when I have tried to download some modules  pip3 8 issued following error  pip is configured with locations that require TLS SSL  however the ssl module in Python is not available   I have searched for the root of my problem and found out that there is a system dependent portion of the python build which is called by system independent one  In case of missing ssl you just needed to open python terminal and check whether is  ssl present   gt  gt  gt  help  modules        sre                enum                pwd                 wave  ssl                errno               py compile          weakref  stat               faulthandler        pyclbr              webbrowser      If not your system dependent ssl module part is missing  You can check it also by listing content of  lt python installation root gt  lib python3 8 lib-dynload   gt ls   lib python3 8 lib-dynload   grep ssl  ssl cpython-38-x86 64-linux-gnu so  The problem was caused as written by PengShaw by missing libssl-dev during the build  Therefore you have to follow the recommended python installation flow  First install prerequisites and then build and install the python  Installation without devel versions of libs resulted in my case in the missing system dependent part  In this  case  ssl  Note that the devel lib name differs for Debian and CentOS  therefore check whether the installation hints posted on net are suitable for your specific Linux system type  For Debian  sudo apt install -y libbz2-dev libffi-dev libssl-dev   configure --enable-optimizations make make altinstall   For CentOS  sudo yum -y install bzip2-devel libffi-devel openssl-devel   configure --enable-optimizations make make altinstall  It is for sure a good idea to list configuration options prior the configuration and evtl  use some additional options    configure --help  Last but not least in case you use --prefix for a non-default installation location  remember to add your  lt python installation root gt  lib to your LD LIBRARY PATH

I had a similar problem on OSX 10 11 due to installing memcached which installed python 3 7 on top of 3 6      WARNING  pip is configured with locations that require TLS SSL  however the ssl module in Python is not available    Spent hours on unlinking openssl  reinstalling  changing paths   and nothing helped  Changing openssl version back from to older version did the trick   brew switch openssl 1 0 2e   I did not see this suggestion anywhere in internet  Hope it serves someone

If you are on OSX and have compiled python from source   Install openssl using brew brew install openssl  Make sure to follow the instructions brew gives you about setting your CPPFLAGS and LDFLAGS  In my case I am using the openssl 1 1 brew formula and I need these 3 settings for the python build process to correctly link to my SSL library   export LDFLAGS  -L usr local opt openssl 1 1 lib  export CPPFLAGS  -I usr local opt openssl 1 1 include  export PKG CONFIG PATH   usr local opt openssl 1 1 lib pkgconfig    Assuming the library is installed at that location

You can do either of these two    While installing Anaconda  select the option to add Anaconda to the path    or   Find these  complete  paths from your installation folder of Anaconda and add them to the environment variable      Anaconda   Anaconda Library mingw-w64 bin   Anaconda Library usr bin   Anaconda Library bin   Anaconda Scripts   anaconda Library   anaconda condabin  Add the above paths to the  Path  system variable and it should show the error no more

I had the same issue trying to install python3 7 on an ubuntu14 04 machine  The issue was that I had some custom folders in my PKG CONFIG PATH and in my LD LIBRARY PATH  which prevented the python build process to find the system openssl libraries   so try to clear them and see what happens   export PKG CONFIG PATH    export LD LIBRARY PATH

The ssl module is a TLS SSL wrapper for accessing Operation Sytem  OS  socket  Lib ssl py   So when ssl module is not available  chances are that you either don t have OS OpenSSL libraries installed  or those libraries were not found when you install Python  Let assume it is a later case  aka  you already have OpenSSL installed  but they are not correctly linked when installing Python    I will also assume you are installing from source  If you are installing from binary  ie  Window  exe file   or package  Mac  dmg  or Ubuntu apt   there is not much you can do with the installing process   During the step of configuring your python installation  you need to specify where the OS OpenSSL will be used for linking     python 3 8 beta   configure --with-openssl  your OpenSSL root    So where will you find your installed OpenSSL directory     ubuntu  locate ssl h   grep   openssl ssl h    home user  linuxbrew Cellar openssl 1 0 2r include openssl ssl h  home user envs py37 include openssl ssl h  home user miniconda3 envs py38b3 include openssl ssl h  home user miniconda3 include openssl ssl h  home user miniconda3 pkgs openssl-1 0 2s-h7b6447c 0 include openssl ssl h  home user miniconda3 pkgs openssl-1 1 1b-h7b6447c 1 include openssl ssl h  home user miniconda3 pkgs openssl-1 1 1c-h7b6447c 1 include openssl ssl h  usr include openssl ssl h   Your system may be different than mine  but as you see here I have many different installed openssl libraries  As the time of this writing  python 3 8 expects openssl 1 0 2 or 1 1      Python requires an OpenSSL 1 0 2 or 1 1 compatible libssl with X509 VERIFY PARAM set1 host      So you would need to verify which of those installed libraries that you can use for linking  for example   usr bin openssl version  OpenSSL 1 0 2g  1 Mar 2016     configure --with-openssl   usr  make  amp  amp  make install   You may need to try a few  or install a new  to find the library that would work for your Python and your OS

I was having the same problem for the last two days and only have fixed it right now   I had tried to use --trust-host option with the DigiCert High Assurance EV Root CA pem did not work  I couldn t install the ssl module  It tells it cannot be installed for python versions greater than 2 6   setting the  PIP CERT variable didn t fix it either and I had libssl1 0 2 and libssl1 0 0 installed  Also worth mentioning I didn t had a    pip pip conf file  and creating it didn t solve the bug either   What finally solved it  was installing python3 6 with make again  Download the Python-3 6 0 tgz from the website  run configure then make  make test and make install  Hope it works for you

The python documentation is actually very clear  and following the instructions did the job whereas other answers I found here were not fixing this issue     first  install python 3 x x from source using  for example with version 3 6 2 https   www python org ftp python 3 6 2 Python-3 6 2 tar xz make sure you have openssl installed by running brew install openssl unzip it and move to the python directory  tar xvzf Python-3 6 2 tar xz  amp  amp  cd Python-3 6 2 then if the python version is  lt  3 7  run    CPPFLAGS  -I  brew --prefix openssl  include       LDFLAGS  -L  brew --prefix openssl  lib        configure --with-pydebug  5  finallly  run make -s -j2  -s is the silent flag  -j2 tells your machine to use 2 jobs

If you are on Windows and use anaconda this worked for me   I tried a lot of other solutions which did not work  Environment PATH Variable changes       The problem can be caused by DLLs in the Windows System32 folder  e g  libcrypto-1 1-x64 dll or libssl-1 1-x64 dll or others  placed there by other software   The fix was installing openSSL from https   slproweb com products Win32OpenSSL html which replaces the dlls by more recent versions

NOT on Windows   This made me tear my hair out for a week  so I hope this will help someone I tried everything short of re-installing Anaconda and or Jupyter  Setup  AWS Linux Manually installed Anaconda 3-5 3 0 Python3  3 7  was running inside anaconda  ie    anaconda3 bin python  there was also  usr bin python and  usr bin python3  but these were not being used as most of the work was done in Jupyter s terminal   Fix In Jupyter s terminal  cp  usr lib64 libssl so 10   anaconda3 lib libssl so 1 0 0 cp  usr lib64 libcrypto so 10   anaconda3 lib libcrypto so 1 0 0 What triggered this  So  this was all working until I tried to do a conda install conda-forge I m not sure what happened  but conda must have updated openssl on the box  I m guessing  so after this  everything broke  Basically  unknown to me  conda had updated openssl  but somehow deleted the old libraries and replaced it with libssl so 1 1 and libcrypto so 1 1  Python3  I guess  was compiled to look for libssl so 1 0 0 In the end  the key to diagnosis was this  python -c  quot import ssl  print  ssl OPENSSL VERSION  quot  gave the clue library  quot libssl so 1 0 0 quot  not found The huge assumption I made is that the yum version of ssl is the same as the conda version  so just renaming the shared object might work  and it did  My other solution was to re-compile python  re-install anaconda  etc  but in the end I m glad I didn t need to  Hope this helps you guys out
