  • 1.  Unable to Install a few Python Packages

    Hello,
    I am new to Python3 and AIX alike. I am developer and do not know much of admin work.

    While trying to install LXML, PANDAS, NUMPY, SCIPY and PYODBC packages, the install failed. Upon investigating, it was found that the necessary CC and FORTRAN compilers are not present in the server.

    I had tried most of the solutions suggested in the forums and in the AIX toolbox community, but nothing worked, I had also reached out to my in house UNIX admins and the solutions they suggested did not work either.

    My admin suggested the use the following two lines in my .profile. However, that also did not work.

    export CC=gcc
    export FC=gfortran

    I am not sure if this is OS related or tool related and hence the posting the question after having stuck with this for over a month. Any suggestions are welcome.

    sudo python -m pip install lxml

    Hi There

    Check output of rpm -qa gcc to see if the Open Source GNU compiler is installed.
    AIX has xlC but it may be that your installation required gcc compiler.

    Thanks a lot! This helped.

    I used the approach of setting the PATH and that worked
    After that I finally linked python3 binaries  from /opt/freeware/bin to /usr/bin, because I don't like having /opt/freeware/bin before /usr/bin permanently in my path.
