SOLVED: OSX or macOS Sierra, error while installing python with python: zipimport.ZipImportError: can't decompress data; zlib not available

Created:

The error

If you are installing python with pyenv and get the error:

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

Zlib and xcode already installed

Something is broken on your system, try to reexecute:

xcode-select --install

Check for empty space

First Check that uou have enough freespace in your harddrive, especially on the /tmp. Use the command df -h to check freespace. Usually this error is shown when no space is available without warning.

Naive solution: install zlib

If you have space upgrade zlib version or install it.

brew update
brew upgrade
brew install zlib
export CFLAGS="-I$(brew --prefix openssl)/include -I$(xcrun --show-sdk-path)/usr/include" 
export LDFLAGS="-L$(brew --prefix openssl)/lib"
pyenv install 3.6.0
