Failed to install zbar with pip on Windows

Question

I\'m trying to install zbar on my Windows x64 machine:

pip install zbar

And this is what I got:

Collecting zba         


        

Answer 1

You are trying to install zbar package with pip. When doing so, pip downloads the source and tries to compile the C/C++ source code of this project.

To do such a thing, you need a C/C++ compiler and having all dependencies. It may be complicated to have pip compiles this package.

The other solution is to download a binary wheel that embeds all binaries. zbar developers propose to download a binary wheel from their GitHub webpage

You can download this binary wheel, that targets a Windows Python 2.7 64 bit installation.

All you have to do is:

• open a Windows cli with Windows+R and by running inside cmd
• go to the directory where you have downloaded the whl file, with cd instructions
• run pip install zbar-0.10-cp27-none-win_amd64.whl

For example, the command can be

pip install zbar-0.10-cp27-none-win_amd64.whl

If you have several Python installations, make sure to use the correct pip program.

You can do it for any package with some code that has to be compiled
