Error Installing Hachoir-metadata |Command "python setup.py egg_info" failed with error code 1 in...\hachoir-metda

I am installing hachoir-metadata from reference[3]. I have completed the following for the installation of hachoir-metadata:

conda create -n hachoir-metadata pip python=3.5 
activate hachoir-metadat
pip install --upgrade hachoir-metadata

I am using the software versions below:

Python Version 3.5.5 Anaconda: 3.6.5

I get an error stating Command "python setup.py egg_info" failed with error code 1 in...\hachoir-metda which is shown below. Anaconda Command Prompt

I have completed the following in attempt to fix the problem:

1)Installed setuptools

pip install --upgrade setuptools[1]

2)Installed ipykernel

conda create -n ipykernel pip python=3.5 

activate ipykernel

pip install --upgrade ipykernel

Non of the above work. Firstly, when analyzing the error it is due to a syntax issue. Therefore, could the error be caused by the fact that the Python version is incompatible(i.e. hachoir-metadata uses an old version of python but this should not be the case right)?

What can be done to solve this issue?

Solution

  • So this it what I discovered (NB: that I am new to python), hachoir metadata works with python 2 and can not work with python 3+.

    There are a few options to address this:

    1)Conversion of 2.x code to 3.x for pure Python is generally a straightforward mechanical translation. There's a program called 2to3 .

     Step 1) open command prompt and open that folder in command prompt then 
 type python C:/Python35/Tools/Scripts/2to3.py -w yourfile name [1]

    2)You can also Port codes from python 2 to python 3 [2]

    3)I also found this,Hachoir3 is written for Python 3.3+, it uses the new yield from syntax.[3]

    Lucky Us! Guess I'm going with option 3.
