pip on python3: Can't decompress data; zlib not available
Getting pip3.4 to work
Want Python3.4 on your debian with virtualenv and pip? That’s what I wanted. However, I didn’t get pip automatically, and when I tried to install it, python gave me
“Can’t decompress data; zlib not available”
Spent a whole lot of time on this. Seems like installing 3.4 properly (with —with-zlib parameter when configuring) makes your life easier.
Step 1) Install Python3.4
wget https://www.python.org/ftp/python/3.4.2/Python-3.4.2.tgz
tar -xvf Python-3.4.2.tgz
cd Python-3.4.2
./configure --with-zlib
sudo make
sudo make install
You should now have pip3.4, yes? and pyvenv-3.4? Good.
Step 2) make the virtualenv and activate it
Oh, yes. Python 3.4 comes with a virtualenv. It’s called pyvenv. It works like it used to (except no —distribute flag)
pyvenv env
source env/bin/activate
