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++
If it is still not working, you can try this
sudo apt-get install build-essential
in my case, it solved the problem.
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.
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

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

Uninstalling psycopg2-2.7.7:

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.
I am clueless here. I need to upgrade to python 3.8.0. So, I run this:
sudo apt-get install python3 3.8.0
But I get the following message:
As you can see. It writes "python3 is already the newest version". It is not.
Also, I get the "held broken packages" error after that. I am not sure if they are related.
you might have the newest version of tthat particular's repository.
try here:
sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt-get update
sudo apt-get install python3.8
sudo apt install python3.8-distutils
python3.8 -m pip install --upgrade pip setuptools wheel
I have just created a virtual environment on my machine (I am running on ubuntu 18.04 LTS). I have the python version of 3.6.7 and now I want to install mysqlclient into my virtual environment.
After I do pip install mysqlclient it didn't work, instead it gave me errors saying;
Command "python.py egg_info" failed with error code 1 in /tmp/pip-install-zd21vfb3/mysqlclient/', and that the msql_config file is not found.
My setup tools are all up to date.
mysqlclient has a dependency on the mysql client & dev packages being installed. In order to fix this on ubuntu, you have to use apt-get to install a couple of mysql packages.
In your case, it looks like the missing mysql_config might be missing on your system. You can fix that by installing libmysqlclient-dev on ubuntu bionic.
In order to correctly install MySQLClient on a fresh Ubuntu 18.04 LTS you need to install each of the following:
# Replace python3.6 with which ever version of Python3 you are using
sudo apt-get install python3.6-dev
sudo apt-get install mysql-client
sudo apt-get install libmysqlclient-dev
sudo apt-get install libssl-dev
The last one is often missed on answers but is required now.
Only then can you install it via pip. Also make sure to update pip so you are not using version 9 if that installs into your vevn.
I was getting the same error when building my docker container. I tried installing the following in sequence but did not work.
sudo apt-get install mysql-client
sudo apt-get install libmysqlclient-dev
sudo apt-get install libssl-dev
Then this 👇 solved the problem.
sudo apt-get install default-libmysqlclient-dev
Check if you have already installed setuptools.
After that
in terminal
sudo apt-get install libmysqlclient-dev
Then(Keeping in mind to activate the virtual enviroment)
sudo pip3 install mysqlclient
I am trying to install scrapy-deltafetch on ubuntu 14 using pip (v8.1.2 on python 2.7). When I run (sudo) pip install scrapy-deltafetch, I get the following error:
Update:
Complete output from command python setup.py egg_info:
Can't find a local Berkeley DB installation.
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-TVr3UZ/bsddb3/
Any thoughts on how to resolve this?
I have already ran the following:
sudo python ez_setup.py
pip install --upgrade setuptools
as well as
sudo apt-get install python-setuptools
I do have both python3 and python 2.7 on the computer.
I have tried installing bsdb3 but that does not work either. I will look into setting up berkeley db correctly and update here accordingly
Update:
Installing berkeley DB did not solve the issue.
scrapy-deltafetch requires bsddb3.
bsddb3 itself, on Ubuntu Trusty, depends on libdb5.3.
You can either install python-bsddb3 with apt-get, or only apt-get install libdb5.3. pip install scrapy-deltafetch should work after that.
Install libbd-dev first,
sudo apt-get install libdb-dev
then install deltafetch,
# for python2
sudo -H pip install scrapy-deltafetch
# for python3
sudo -H pip3 install scrapy-deltafetch
After I installed Mariadb 10 the Mysql workbench and JPDB client both connect and work fine so next step was get programming with Python (using SQLAlchemy) which seems to require MySQL-python so I went to update that and got:
"mysql_config not found" I looked in the "usual places" and did not see a file...
So I followed some ideas from an earlier question on SO
and tried to install: apt-get install libmysqlclient-dev
which got me to:
The following packages have unmet dependencies:
libmysqlclient-dev : Depends: libmysqlclient18 (= 5.5.35-0ubuntu0.13.10.2) but 10.0.10+maria-1~saucy is to be installed
which kind of hits a brick wall for me
For Centos 7.0 install the following:
yum install mariadb-devel
For Fedora 23+:
dnf install mariadb-devel
Found it! The case is that mariadb has a compatible package, if you have the ppa setup as in http://downloads.mariadb.org/. Just
sudo apt-get install libmariadbclient-dev
Thanks to http://data-matters.blogspot.com/2013/08/install-mysql-python-with-mariadb.html
After this the mysql-python installs correctly
There's NO solution on Ubuntu 16.04
Doing:
sudo ln -s /usr/bin/mariadb_config /usr/bin/mysql_config
Worked for me.
Install the following library:
sudo apt-get install libmariadb-client-lgpl-dev
And create a symbolic link named mysql_config:
ln -s /usr/bin/mariadb_config /usr/bin/mysql_config
For Debian/Ubuntu PPA from https://downloads.mariadb.org/mariadb/repositories/
for MariaDB 10.1: apt-get install libmariadbclient-dev
for MariaDB 10.2: apt-get install libmariadb-dev
for MariaDB 10.3: apt-get install libmariadb-dev-compat
On Ubuntu 17.04 the following worked for me
sudo apt-get install default-libmysqlclient-dev
For Debian Jessie:
sudo apt-get install libmariadb-client-lgpl-dev
sudo ln -s /usr/bin/mariadb_config /usr/bin/mysql_config
