Linux:No module named pip #66

I tried to build cura-build-environment on Linux machine(Lubuntu, Ubuntu and Debian9). When is compiling Python package generate an error that the pip module is not installed. I tried to change the version of python to be installed on python.cmake (3.5.2,3.5.4,3.5.7) but nothing, the error persist. In OS is installed pip. Thanks

I'd expect the version of Python to be installed from cura-build-environment to be separate from the one installed on your system. For me it works (Ubuntu 19.04) so it should be the same as you! Perhaps it needs to install Pip separately into that CPython installation? I'd expect the CPython installation to be shipped with Pip though...

These are the steps I followed:

installed Ubuntu 19.04 in a VM
Installed gcc and g ++
cmake installed
installed gfortran
started compiling cura-build-environment Where i'm doing wrong?

I don't know, seems like those are the correct steps.

I've more or less given up on trying to maintain a build system that works on all computers. I'm happy if it works on Ultimaker's build servers and on my own computers. For others it's too hard to debug remotely.

If you can find a way to ensure that Pip is included with the CPython version you're building, please let me know. Maybe we need to do something like a find_package(PythonPip) with a custom find script as well.

@DapDeveloper You also need SSL to use pip. Could you run apt install libssl-dev and try again? If SSL is missing, it will not compile the SSL modules in Python and pip will not work.
