I'm using python on a Linux cluster (without root access) and want to use the numpy module. After downloading numpy from Numerical Python, extracting and trying to install it with:

python setup.py install --home=/home/"myusername"/"myfolder" 

(as I have successfully done with previous python modules), I get the error:

SystemError: Cannot compile 'Python.h'. Perhaps you need to install python-dev|python-devel.

So to try and locally install python-dev, I downloaded the .deb from python2.7-dev_2.7.10-2_amd64.deb and extracted it in "myfolder" as described in http://www.g-loaded.eu/2008/01/28/how-to-extract-rpm-or-deb-packages/, however this did not solve the previous error and I cannot find any more relevant help.

I do not have access to apt-get or dpkg.

    Have you tried asking the system administrator to install the packages you require? It seems to me it would be a more sensible way forward than trying to pick packages apart and install them in non-standard places – roaima Jun 12 '15 at 21:26
  • I would if it was easiest, however I'm using a few different clusters, most of them without much installed and am trying to make my own setup across them as consistent as possible. – Luce Jun 15 '15 at 20:57

You can download the source for python-2.7.10 from the python.org site. Once you extract .tar.xz archive you will find the Include directory that contains the missing missing header files.

You can tell python setup.py ... to look in this directory as well by setting

export CPLUS_INCLUDE_PATH=/path/to/your/extracted/Python-2.7.10/Include
  • This worked, I just have to from now on make sure I'm using my python installation and not the system wide one. – Luce Jun 15 '15 at 21:18

I agree with the comment @roaima made; however, you can always use alien to convert the .deb to a .tgz and then untar it.

So, after making alien you'd use alien -tc package.deb.

  • I can't use alien either. – Luce Jun 15 '15 at 20:55
  • You can alien it on another system, upload the .tgz file to server and use it. – hegez Jan 27 '18 at 12:57
