Could not install the C++-simulator #351

Closed PabloAMC closed 3 years ago

PabloAMC commented 4 years ago

I've been basically unable to install the fast version of ProjectQ. My steps were

  1. Create an environment conda create -n projectq python=3.5 conda activate projectq

  2. Followed the steps in https://projectq.readthedocs.io/en/latest/tutorials.html#detailed-instructions-and-os-specific-hints for Mac, in particular a) xcode-select --install b) sudo easy_install pip c) python -m pip install --user projectq

In the last step I invariable get 

  1 warning and 1 error generated.

  Exception:
  Could not install the C++-Simulator.
  ProjectQ will default to the (slow) Python simulator.
  Use --without-cppsimulator to skip building the (faster) C++ version of the simulator.

About the upgrading pip thing, it proves a bad idea since it won't fit with version 3.5, which is the needed one. I have also tried the way indicated in the link but the same thing happens.

How can one install the fast version?

It's better using Google Colab, which is an Online Platform to work on any Projects. !pip install projectq For any other queries Check this out. You can experience fast version of ProjectQ here. For any further queries: https://github.com/SiddTim/Terminal_Commands-in-Google-Colab

@PabloAMC Did you solve your issue in the end? If you have not done so already, please try with the latest ProjectQ version. Also, try to add the -v flag to your pip command:

python -m pip install --user -v projectq
