The python3-setuptools package provides the easy_install3 command, which we can use to install pip (not sure why it's not included with Python beta as it normally is with standard releases?)
apt-get update && \
apt-get install -y -q wget && \
apt-get install -y -q build-essential python3-setuptools && \
apt-get build-dep -y -q python3 && \
wget https://www.python.org/ftp/python/3.6.0/Python-3.6.0b1.tgz && \
tar xf Python-3.6.0b1.tgz && \
rm Python-3.6.0b1.tgz && \
cd Python-3.6.0b1/ && \
./configure && \
make && \
./python --versionDon't try to move the ./python executable into /usr/local/bin/ as it won't be able to locate the other libraries/modules it links to. If anyone knows how to solve that issue, then please let me know!
Python looks here for packages:
./python " starts REPL
>>> import sys
>>> print('\n'.join(sys.path))
/usr/local/lib/python36.zip
/Python-3.6.0b1/Lib
/Python-3.6.0b1/build/lib.linux-x86_64-3.6So if we install Jinja2 we can see where it's installed:
pip install jinja2
/usr/local/lib/python3.4/dist-packages | grep -i jinMeaning we can now modify the `` environment variable to utilise that package.
export PYTHONPATH="$PYTHONPATH:/usr/local/lib/python3.4/dist-packages"So now if we open a REPL again with the new Python we can import the package:
./python " starts REPL
>>> import sys
>>> print('\n'.join(sys.path))
/Python-3.6.0b1
/usr/local/lib/python3.4/dist-packages " see it's there <<
/usr/local/lib/python36.zip
/Python-3.6.0b1/Lib
/Python-3.6.0b1/build/lib.linux-x86_64-3.6
import jinja2 " this now works √The downside to this approach is that the module might not be compatible with the new beta release of Python we've just installed
