On RHEL 6.6, I installed Python 3.5.1 from source. I am trying to install pip3 via get-pip.py, but I get 

Traceback (most recent call last):
  File "get-pip.py", line 19177, in <module>
    main()
  File "get-pip.py", line 194, in main
    bootstrap(tmpdir=tmpdir)
  File "get-pip.py", line 82, in bootstrap
    import pip
zipimport.ZipImportError: can't decompress data; zlib not available

It works for the Python 2.6.6 installed. I have looked online for answers, but I cannot seem to find any that works for me.

edit: yum search zlib

jzlib.i686 : JZlib re-implementation of zlib in pure Java

  • I run python3 get-pip.py to show the error message above, but it works for python get-pip.py. Yes, I can run yum search zlib.

  • Based on your comments, you do have zlib installed, but perhaps there's a python-zlib wrapper you need?

Ubuntu 16.10+ and Python 3.7 dev

sudo apt-get install zlib1g-dev

Note: I only put this here because it was the top search result for the error, but this resolved my issue.

Update: also the case for ubuntu 14.04LTS and base kernel at 4.1+

Simply copy paste this code:

CFLAGS="-I$(brew --prefix readline)/include -I$(brew --prefix openssl)/include -I$(xcrun --show-sdk-path)/usr/include" \
LDFLAGS="-L$(brew --prefix readline)/lib -L$(brew --prefix openssl)/lib" \
PYTHON_CONFIGURE_OPTS=--enable-unicode=ucs2 \
pyenv install -v 3.6.0

    It's macOS only solution (and brew also should be installed as pre-requisite). Still - good partial solution

Throwing my 2cents. I've been dealing with this issue for the past 3 hours and realized that python3.6 for me was installed was in /usr/local/bin/.

I remade the configure with --prefix==/usr/bin and pip installed.

Installing collected packages: setuptools, pip Successfully installed pip-9.0.1 setuptools-28.8.0

The zlib module is an optional feature for python and it seems that the version of python3.5 in RHEL 6.6 does not include it. You can verify this:

python3 -c "import zlib"

So you'll either need to obtain a zlib enabled version of python (or python libraries) or rebuild python from source with the zlib feature enabled - see here for help: https://stackoverflow.com/questions/12344970/building-python-from-source-with-zlib-support
