Pip Cannot Confirm Ssl Certificate: Ssl Module Is Not Available
I am trying to install RPi.GPIO for Python 3.6 on my Raspberry Pi Zero W, but somehow it won't connect to the python.org website. I have pip installed for 2.7, 3.0, and 3.6 install
Solution 1:
Before installing python 3.6 you need to install the libraries needed.
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
Do you have these installed on the PI?
More details here
Solution 2:
I encounter the same problem,finally I solved it by following
Check whether the openssl-devel has been installed. My OS is centos6 and the installing command is as following
yum install openssl-devel -y
Edit python source configure file
vi /{yourpythonsource}/Modules/Setup
. Uncomment some of content as following
# Socket module helper for socket(2)
_socket socketmodule.c timemodule.c
# Socket module helper for SSL support; you must comment out the other # socket line above, and possibly edit the SSL variable: #SSL=/usr/local/ssl
_ssl _ssl.c \
-DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \
-L$(SSL)/lib -lssl -lcrypto
recompile python.
cd /{yourpythonsource}
make && make install
Now pip3 should be ok.
