error: command 'gcc' failed with exit status 1 while installing eventlet

I wanted to install eventlet on my system in order to have "Herd" for software deployment.. but the terminal is showing a gcc error:

Why can't Python.h be found?

Your install is failing because you don't have the python development headers installed. You can do this through apt on ubuntu/debian with:

sudo apt-get install python-dev 

for python3 use:

sudo apt-get install python3-dev

For eventlet you might also need the libevent libraries installed so if you get an error talking about that you can install libevent with:

sudo apt-get install libevent-dev

For Fedora:

sudo yum install python-devel

sudo yum install libevent-devel

and finally:

sudo easy_install gevent

What worked for me on CentOS was:

sudo yum -y install gcc
sudo yum install python-devel

For Redhat Versions(Centos 7) Use the below command to install Python Development Package

Python 2.7

sudo yum install python-dev

Python 3.4

sudo yum install python34-devel

Python 3.6

sudo yum install python36-devel

If the issue is still not resolved then try installing the below packages -

sudo yum install python-devel

sudo yum install openssl-devel

sudo yum install libffi-devel

On MacOS I had trouble installing fbprophet which requires pystan which requires gcc to compile. I would consistently get the same error: command 'gcc' failed with exit status 1

I think I fixed the problem for myself thus:

I used brew install gcc to install the newest version, which ended up being gcc-8

Then I made sure that when gcc ran it would use gcc-8 instead.

It either worked because I added alias gcc='gcc-8 in my .zshrc (same as .bashrc but for zsh), or because I ran export PATH=/usr/local/bin:$PATH (see comment)

Also: all my attempts were inside a virtual environment and I only succeeded by installing fbprophet globally (with pip), but still no success inside a venv

This is an old post but I just run to the same problem on AWS EC2 installing regex. This working perfectly for me

sudo yum -y install gcc

and next

sudo yum -y install gcc-c++

try this :

sudo apt-get install libblas-dev libatlas-base-dev

I had a similar issue on Ubuntu 14.04. For me the following Ubuntu packages

On MacOS I also had problems trying to install fbprophet which had gcc as one of its dependencies.

After trying several steps as recommended by @Boris the command below from the Facebook Prophet project page worked for me in the end.

conda install -c conda-forge fbprophet

It installed all the needed dependencies for fbprophet. Make sure you have anaconda installed.

If it is still not working, you can try this

sudo apt-get install build-essential

in my case, it solved the problem.

This page is gonna save your life, for all further lib issues that are forthcoming,

For Alpine(>=3.6), use

apk --update --upgrade add gcc musl-dev jpeg-dev zlib-dev libffi-dev cairo-dev pango-dev gdk-pixbuf-dev

For CentOS 7.2：

LSB Version:	:core-4.1-amd64:core-4.1-noarch
Distributor ID:	CentOS
Description:	CentOS Linux release 7.2.1511 (Core)

Install eventlet:

sudo yum install python-devel
sudo easy_install -ZU eventlet

For openSUSE 42.1 Leap Linux use this

sudo zypper install python3-devel

I am using MacOS catalina 10.15.4. None of the posted solutions worked for me. What worked for me is:

 >> xcode-select --install
xcode-select: error: command line tools are already installed, use "Software Update" to install updates

>> env LDFLAGS="-I/usr/local/opt/openssl/include -L/usr/local/opt/openssl/lib" pip install psycopg2==2.8.4

    Running setup.py install for psycopg2 ... done

use pip3 for python3

if you are on Mac as myself, try this in your terminal: xcode-select --install

Then accept the installation request, and it works afterwards as described in this issue

Build from source and install, this is fixed in the latest release (10.3+):

mkdir -p /tmp/install/netifaces/
cd /tmp/install/netifaces && wget -O "netifaces-0.10.4.tar.gz" "https://pypi.python.org/packages/source/n/netifaces/netifaces-0.10.4.tar.gz#md5=36da76e2cfadd24cc7510c2c0012eb1e"
tar xvzf netifaces-0.10.4.tar.gz
cd netifaces-0.10.4 && python setup.py install

Similarly I fixed it like this (notice python34):

sudo yum install python34-devel

sudo apt install gcc

It works for PyCharm on Ubuntu 20.10.

If you are migrating to a more modern version of python3 e.g. python3.5 to python3.8 You may want to check/upgrade the versions of the library that are failing if you have already installed the recommended libraries to handle gcc building python3-dev + other libraries as suggested.

It depends on the package. Some versions of the packages may not be supported on later versions of python3.
