That is the file.Ĭhange PYTHON to python version you have, python/python3. I know the secret now, it comes from the cython source code. I still had this problem, the line: #include "Python.h"Īnd some others, I can edit them manually, it is a bad practice. sudo apt-get install python-dev # for python2.x installs I have installed all packages as was recommended in some answers. However, when I updated the image to python:3, it worked fine. For example, I was trying to install asyncpg~=0.24.0 on python:3.9.4-slim, which generated the same error as you saw. NOTE: If you're getting the error when compiling C++, use CPLUS_INCLUDE_PATH.Īlternatively, you may prefer to use another Docker image. # Since the previous command contains a purposeful error, remove it before the next runĪRG C_INCLUDE_PATH='/usr/include/python3.6m' RUN rpm -ql python36-devel.x86_64 | grep -i "Python.h" & fake_command_so_docker_fails_and_shows_us_the_output # Find the install directory of `Python.h`, for me it was /usr/include/python3.6m Rpm -ql python36-devel.x86_64 | grep -i "Python.h"ĭocker solution: # Install python3-devel like everyone says # Find the install directory of `Python.h` Non-docker solution: # Install python3-devel like everyone says For reference, I was trying to pip install something on an Amazon Linux AMI base Docker image for Python 3.6. Here is yet another solution, because none of these solutions worked for me. Mine was /home/ubuntu/workspace/blender-git/lib/linux_centos7_x86_64/python/include/python3.7m/Python.h, so I did: export CPPFLAGS=-I/home/ubuntu/src/blender-deps/Python-3.7.7/Include Then, you can set a compiler flag that will get used by gcc when called by pip. home/ubuntu/src/blender-deps/Python-3.7.7/Include/Python.h home/ubuntu/miniconda3/envs/sim/include/python3.7m/Python.h home/ubuntu/miniconda3/include/python3.8/Python.h home/ubuntu/workspace/blender-git/lib/linux_centos7_x86_64/python/include/python3.7m/Python.h In the output, you will see system python headers, and hopefully the one you are looking for, for example: /usr/include/python3.7m/Python.h In this case, the solution is to find the right python header: find / -iname 'Python.h' As it was not system's python, apt install pythonXX-dev didn't work. It happened to me when trying to pip install a package for a Python bundled with an application. In that case, the non-system pip won't find the right version of Python headers. This problem can also arise when you have different Python versions installed and you use a pip that's not the system's one. python 3.8 you may need to install python3.8-dev. Note: python3-dev does not automatically cover all minor versions of python3, if you are using e.g. Sudo apk add python3-dev # for python3.x installsįor apt-cyg ( Cygwin.): apt-cyg install python-devel # for python2.x installsĪpt-cyg install python3-devel # for python3.x installs Sudo apk add python2-dev # for python2.x installs # scheme, which uses py2- and p圓- prefixes Sudo zypper in python3-devel # for python3.x installsįor apk ( Alpine.): # This is a departure from the normal Alpine naming Sudo dnf install python3-devel # for python3.x installsįor zypper ( openSUSE.): sudo zypper in python-devel # for python2.x installs Sudo yum install python3-devel # for python3.x installsįor dnf ( Fedora.): sudo dnf install python2-devel # for python2.x installs Sudo apt-get install python3-dev # for python3.x installsįor yum ( CentOS, RHEL.): sudo yum install python-devel # for python2.x installs Use your package manager to install them system-wide.įor apt ( Ubuntu, Debian.): sudo apt-get install python-dev # for python2.x installs Looks like you haven't properly installed the header files and static libraries for python dev.
