Jep doesn't build for Python 3.7.3 in Windows 10

[muratcanozdemir]

Describe the problem
I tried building Jep to install it in my local Windows 10 machine with every single available MSVC compiler out there, from 14.10 to 14.26, but it always returns this error with VC14.1 missing. I checked the installation folders in my local drive, run the distutils code snippets to trace the result there when it finds a valid VC14 compiler (it finds the correct directory), but the installation script cannot find this, and fails there every single time. Honestly it would be much easier if there would be a .whl installation available, given the difficulties in Windows machines still not completely solved.

Environment (please complete the following information):

• OS Platform, Distribution, and Version: Windows 10 Enterprise, 1909
• Python Distribution and Version: Python 3.7.3
• Java Distribution and Version: JDK 1.8.252
• Jep Version: 3.9.0
• Python packages used (e.g. numpy, pandas, tensorflow): time, socket, logging

Logs
Please attach the complete console output of the build.

Failed to build jep
DEPRECATION: Could not build wheels for jep which do not use PEP 517. pip will fall back to legacy 'setup.py install' for these. pip 21.0 will remove support for this functionality. A possible replacement is to fix the wheel build issue reported above. You can find discussion regarding this at pypa/pip#8368.

How do you run it? Just pip install jep from command prompt? Are you sure it is the right prompt? For example I had to use x64 Native Tools Command Prompt for VS 2019 shortcut in the start menu to start command prompt where jep built successfully. And even though it is a prompt for VS 2019, the build did not succeed until I installed build tools for VS 2015...

Yeah, the correct procedure is to use VS 2015 Build Tools, so not v14.1.

Greetings - we are having the same issue and are using this thread as a guide for solving (we feel we are close). PACHER - can you clarify how you ran the command to install? Your entry seems to indicate you have BOTH VS 2019 and 2015 installed. Did you uninstall 2019 and replace it with 2015?

[peteman001]

Perhaps "muratcanozdemir" could clarify also how this was accomplished successfully?

[peteman001]

Update- in Win 10 we uninstalled VS 2019 and installed Build tools 2015. Then from the Start menu we selected x64 Native Tools Command Prompt and once that window opened we simply typed pip install jep. And it worked.

Thank you leaving these hints.
