Python pip install failing with error code 1

Question

I am working on CentOS6 and have been able to install python2.7. After creating a virtualenv I have started installing various packages of python. I can install some packages easily like requests,etc. but installing packages like Numpy, scipy, gensim, pycurl are a huge pain. It keeps on giving me this error:

By running pip install pycurl from within the virtualenv with python2.7 installed I am running into the problem.

Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-ClD2EM/pycurl

I am not abel to fix this setup.py egg_info problem.

After running yum install libcurl and then running pip install pycurl i got this:

Answer 1

You need a libcurl development library . Get it with yum:

yum install libcurl-devel

EDIT: After you installed it, you appear to have some missing dependencies, still. You need Python development library , get it with yum as follows:

yum install python-devel

If the installation above doesn't work, try rpm instead by download this Python-devel RPM for CentOS . Then install it via rpm:

rpm -ivh python-devel-2.7.5-18.el7_1.1.x86_64.rpm

Answer 2

Debian or Ubuntu derived distributions:

apt-get install build-essential libssl-dev libffi-dev python-dev 

Followed by:

pip install cryptography

Red Hat derived distributions:

yum install gcc openssl-devel libffi-devel python-devel 

Followed by:

pip install cryptograph

Answer 3

You need install libcurl development package of your Linux distribution which provides curl libraries and header files.

Go through all "curl" packages for CentOS and you should find the right one.

Answer 4

The problem can be with missing dependencies for pycurl. Here is my answer to similar question which worked for me. Check it here

Answer 5

For me , I installed all the dependencies

1. pip install --upgrade setuptools
2. sudo yum install gcc
3. yum install python-devel
4. yum install libcurl-devel

After installing above , I was getting the same error , then i upgraded pip previously i was using 7.0.1 then i upgraded to 9.0.1 and it worked for me.

pip install --upgrade pip
