I am running mysql#8.x version on my MacOS, I have installed mysql and mysql-connector-o with brew. Currently brew link with mysql.
Running Django project on my python3 virtual env I am receiving following error -
django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module: No module named 'MySQLdb'.
Did you install mysqlclient or MySQL-python?
and on installing the mysqlclient using pip, I am reciving following error

As jordanm pointed it out, the issue was exactly with the missing openssl libraries, for which I followed these steps to fix my issue -
Installing openssl
brew install openssl
Now
pip install mysqlclient should work.
If it doesn't and still shows the same error library not found for -lssl, you could also try to link against brew's openssl:
env LDFLAGS="-I/usr/local/opt/openssl/include -L/usr/local/opt/openssl/lib" pip install mysqlclient
if this still does not work, you might need to use the --no-cache option of pip, e.g.
env LDFLAGS="-I/usr/local/opt/openssl/include -L/usr/local/opt/openssl/lib" pip --no-cache install mysqlclient
After installing openssl via Homebrew I placed
export PATH="/usr/local/opt/openssl/bin:$PATH"
export LDFLAGS="-L/usr/local/opt/openssl/lib"
export CPPFLAGS="-I/usr/local/opt/openssl/include"
in my .bash_profile and ran
source .bash_profile
and then
pip install mysqlclient

I am running Centos7 with Python 3.6. I am trying to install pycrypto with the command "pip3 install pycrypto". I also installed the dev tools, so gcc is installed. I am getting the following output.
What am I missing?

That did not work, but I did find the answer in the article.
I ran "yum -y install python3-devel" and this fixed my issue. I was then able to install pycrypto.
I also had the same issue for CentOS.
However, it turned out I was missing one of the dependencies.
sudo yum install gcc
sudo yum install gcc-c++
sudo yum install python-devel
sudo pip install pycrypto
I tried to install a python package from PyPI with the following command
sudo pip3 install switcheo
The installation fails and show this error message:

Install the libssl-dev package
On Ubuntu, it's as simple as sudo apt-get install libssl-dev
On mac, you need to install openssl: brew install openssl
If that doesn't work, you need to install Homebrew. You should use Homebrew, it makes installing much easier.
If that still doesn't work, you can install libssl-dev and make a symlink:
ln -s /usr/local/Cellar/openssl/1.0.2p/lib/libssl.dylib /usr/local/lib/
I am trying to install cartopy on OS X 10.10 (Yosemite). My python is installed using macports and when I run:
sudo pip install cartopy
I get the following error:

Note that I installed the dependencies as noted here and geos_c.h can be found in /opt/local/include. It seems like pip fails to find this dependency in the macports tree.
Did anyone experienced this kind of problem? How can I fix it?
This question was also raised as an issue at https://github.com/SciTools/cartopy/issues/535.
There was recently a bit of work to improve the pip install cartopy experience. Would you mind trying it again with cartopy v0.12.0.
See https://github.com/SciTools/cartopy/issues/610 for reference.
This is to answer the last question from Dror, since I am using macports and "pip install cartopy" failed to find "proj_api.h". To solve this:
You need to make sure that the proj port is installed: sudo port install proj
Help pip to locate the header in "/opt/local/include": CFLAGS="-I/opt/local/include" pip install cartopy
Cheers and HTH
I'm getting error installing Scrapy on my ubuntu box. I'm using pip to install Scrapy. I'm aware that it needs setuptools to be installed. I got that installed using the script provided in setuptools website.

Any Idea where the process goes wrong? I've got gcc and g++ installed already.
From the error fatal error: Python.h: No such file or directory it looks like python development headers are not installed. Try this command and then try to install again.
sudo apt-get install python-dev
For installing libevent library apply this command,
sudo apt-get install libevent-dev
I figured this out on ubuntu 14.04 by (A) actually following the scrapy docs for installing on ubuntu, then (B) an error that a lot of others were getting, by following a S/O solution Error while starting new scrapy project
(A) http://doc.scrapy.org/en/1.0/topics/ubuntu.html#topics-ubuntu
then
(B)
sudo pip install pyasn1 --upgrade
Right after installing Fedora 23 that's what I did (may works on Ubuntu):
[root#x ~]# pip install scrapy
[root#x ~]# dnf install python-cffi
[root#x ~]# dnf install openssl-devel
[root#x ~]# dnf install gcc
[root#x ~]# dnf install redhat-rpm-config
[root#x ~]# dnf install libxml
[root#x ~]# dnf install libxml2-devel
[root#x ~]# dnf install libxml-devel
[root#x ~]# dnf install glib2-devel gnet2-devel
[root#x ~]# dnf install libxslt-devel
sudo apt install python3-scrapy
I have tried this ..and it worked for me.
(You should have the ssh installed)
I'm trying to compile pymssql for python 2.5. I'm doing this because I think the version of pymssql I have is compiled for python 2.4. This is the error I get which makes me think that:

Anyway I'm on Ubuntu 10.10 and have installed python2.5 and python2.5-dev via the deadsnakes ppa. I've created an virtualenv with using python2.5 like so

Turns out I needed to install pyrex from pip.
