Cx_freeze Build Error?

I am trying to create a binary from a python,flask and boto3 app. I am having trouble running the pip install cx_Freeze command too work. I am getting the following error : It see

Solution 1:

Just do

sudo apt install zlib1g-dev

I was trying to install cx-freeze to convert some python code to an exe but the problem was /usr/bin/ld: cannot find -lz just like you. The file being fetched is compressed (cx_Freeze-5.1.1.tar.gz) so you need zlib. Of course use pip3 for python3.

Solution 2:

pip never installs system libraries, it only concerns itself with Python libs.

It seems you need to install zlib before installing cx_Freeze.

Another tool to generate binaries is PyInstaller.
