Getting error when trying to install python

Question

I have downloaded python-3.6.1.tar.xz. then I extracted it. There is a file README.rst. this is the instruction file. and has the instruction how to install.

On Unix, Linux, BSD, macOS, and Cygwin::

./configure
make
make test
sudo make install

Completed 1st two steps ie upto make without no error. But when I make test then get these errors.

FAILED (failures=1)
test test_venv failed
1 test failed again:
    test_venv

Total duration: 4 min 13 sec
Tests result: FAILURE
Makefile:1018: recipe for target 'test' failed
make: *** [test] Error 1

I have created a file with the error and shared it Google drive. Click Here for the full stack trace.

The relevant portion of the error is:

Answer 1

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

You should install zlib1g-dev and change your configure step like this:

./configure --with-zlib=/usr/include

Now, try this:

 make clean
 apt-get install zlib1g-dev
 ./configure --with-zlib=/usr/include
 ...

You can read more in Configure and compile Python with Zlib

When I was trying to install Python 3.7.3 through pyenv , I got this same error. It was solved by ensuring that I had the prerequisites to my operating system, with the following:

sudo apt-get install -y make build-essential libssl-dev zlib1g-dev libbz2-dev \
libreadline-dev libsqlite3-dev wget curl llvm libncurses5-dev libncursesw5-dev \
xz-utils tk-dev libffi-dev liblzma-dev python-openssl git

I found this in pyenv Common build problems , thanks to agibalov .

On MacOS the issue is often that an XCode update has removed Zlib. Running the following will solve it:

xcode-select --install
