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>
  File "get-pip.py", line 194, in main
  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

  • can you show the exact command. – Mongrel Jun 24 '16 at 3:42
  • can you search for zlib package. – Mongrel Jun 24 '16 at 3:54
  • 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. – Flair Jun 27 '16 at 17:36
  • Based on your comments, you do have zlib installed, but perhaps there's a python-zlib wrapper you need? – Edward Falk Jun 27 '16 at 19:10
  • How would I go about doing that? – Flair Jun 28 '16 at 20:29

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+

  • This should be the current answer. Thanks – jamescampbell Oct 8 '19 at 18:18

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

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

you don't have decompress tool,You should install zlib .

yum list python-gzipstream

If not then run the below to install

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
