Answer 1

I also had a similar problem in which the cmd/PowerShell told me that I was missing a version of Windows Visual C++, so I followed what was written on THIS site, so I didn't have this problem anymore (I also rebooted, for safety):

1. Install using any ONE of these choices:
   • Microsoft Build Tools for Visual Studio
   • Alternative link to Microsoft Build Tools for Visual Studio .
   • Offline installer: vs_buildtools.exe
2. Select: Workloads → C++ build tools.
3. Install options: select only the “Windows 10 SDK” (assuming the computer is Windows 10). Optionally, if you want to use MSVC cl.exe C/C++ compiler from the command line, additionally select the C++ build tools, which takes an additional 2 GB disk space.

Moreover, to avoid problems I preferred to install Python or because they are the ones with which it has been tested (as indicated by the requirements on the github page ).

After which (again according to the instructions) I installed QARK using:

pip install -r requirements.txt
pip install . --user

In the end, to make it work I had to put in the path of the environment variables these definitions: C:\\Users\\user\\AppData\\Roaming\\Python\\Scripts (if you are using Python 2.xx) C:\\Users\\utente\\AppData\\Roaming\\Python\\Python36\\Scripts (if you are using Python 3.xx)

After that I didn't have any problems running it.
I hope I have been helpful! 🤞

Answer 2

I tried solutions above but still getting the error.

Command errored out with exit status 1: python setup.py egg_info Check the logs for full command output.

I'm new to python and would highly appreciate any help
