zipimport.ZipImportError: can't decompress data; zlib not available

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

    Traceback (most recent call last):
      File "", line 19177, in <module>
      File "", line 194, in main
      File "", 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.

    can you search for `zlib` package.

    I run `python3` to show the error message above, but it works for `python`. 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?

    How would I go about doing that?

    on macos, we can `brew install zlib`

    I fixed this by copying `` to `/usr/local/lib/python*/lib-dynaload`.

  • 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+

    Thanks! it helped me resolve the issue installing 3.7.1 on Ubuntu 18.04

  • The solution is : # yum install zlib-devel

    I tried that. It says `Setting up Install Process rhel6_latest | 1.9 kB 00:00 Package zlib-devel-1.2.3-29.el6.i686 already installed and latest version Nothing to do`, but I still get the zipimport error.

    did not solve my problem

    This should be the current answer. Thanks

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

    Updated Answer

    first check if its installed

    yum list python-gzipstream

    If not then run the below to install

    yum install python-gzipstream.noarch

    I have this installed on my system

     yum list python-gzipstream
    Loaded plugins: fastestmirror
    Loading mirror speeds from cached hostfile
     * base:
     * epel:
     * extras:
     * updates:
    Available Packages
    python-gzipstream.noarch                                                                1.4.3-1.el6                                                                 epel

    I ran `yum install zlib`. I get that I already have the latest version. I still get the same error.

    check the updated answer

    For `yum list python-gzipstream`, I get `Error: No matching Packages to list `, and for `yum install python-gzipstream.noarch`, I get `No package python-gzipstream.noarch available. Error: Nothing to do`

    can you show is us the output of `yum repolist` & `yum search zlib`.

    For repolist, `repo id repo name status rhel6_latest Red Hat Enterprise Linux 6Server - i386 - latest 11,637 repolist: 11,637`

    I put the search results in the edited question.

  • 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:
