Compiling Python 3.4 is not copying pip

Question

I have compiled Python 3.4 from the sources on Linux Mint, but for some reason it is not copying pip to its final compiled folder (after the make install).

Any ideas?

Answer 1

Just sorted it out. Here it is how to compile python from the sources.

$ ./configure --prefix=/home/user/sources/compiled/python3.4_dev --with-ensurepip=install
$ make
$ make install

If you get "Ignoring ensurepip failure: pip 1.5.4 requires SSL/TLS" error:

$ sudo apt-get install libssl-dev openssl 
$ ls
2to3              idle3    pip3.5    python3           python3.5m         pyvenv
2to3-3.5          idle3.5  pydoc3    python3.5         python3.5m-config  pyvenv-3.5
easy_install-3.5  pip3     pydoc3.5  python3.5-config  python3-config

As you can see pip is copied into target folder, the --with-ensurepip=install is important.

Answer 2

If you are in Redhat linux (centos, fedora) install following package.

yum install openssl-devel -y

Answer 3

According to PEP 453 -- Explicit bootstraping of pip in Python installation:

Installing from source

Just as the prebuilt binary installers will be updated to run python -m ensurepip by default, a similar change will be made to the make install and make altinstall commands of the source distribution. The directory settings in the sysconfig module should ensure the pip components are automatically installed to the expected locations.

After installing from source code, I found that pip3.4 is put in the destination. (No pip nor pip3)
