How to create a Conda environment that uses PyPy?










1















So here is my issue. I've managed to install PyPy using conda with the following command:



conda install -c conda-forge pypy3.5


Unfortunately, when I try to create an environment that uses this pypy3 exectuable, I cannot find a way to do it. If I run pypy3, I get the PyPy shell without any issue and I can also run my programs using pypy3 instead of python.



Though now, I'd like to be able to create a full environment using PyPy if that's possible. I've tried things like the following in vain:



conda create -n pypy3 python=pypy3
conda create -n pypy3 python=pypy3 -c conda-forge


I've tried specifying pypy3.5, and other variations but nothing works.
I can see the pypy3 executable in the bins of my Miniconda installation but I cannot find a way for Conda to use it. I cannot find much on the internet on this since people seem to be asking just for the install of PyPy via Conda, and nothing about creating environments using PyPy.



So here are my questions:



  • Is there already a way to create a Conda environment using PyPy instead of a regular CPython?

  • Is there a way to force Conda to look first locally instead of checking online for distributions?

  • Is there a way to enforce an executable to use as Python when we create an environment with Conda?

  • Would there be a dirty workaround possible creating a regular environment and then forcing this environment to point to my pypy3 executable?

I don't know if anybody can help here. Maybe the solution already exists but I couldn't find much on the subject anyway.



EDIT: As suggested by @darthbith I can use the following command:



conda create -n pypy3 -c conda-forge pypy3.5


But that doesn't do what I would expect. I can use pypy3 to get the shell and execute my Python programs but it is not handled as a regular Python version. I'd like to have PyPy to be considered like any version of Python and be able to use pip to install packages (most pure Python packages should work with PyPy).



I understand that a lot of people would advise against what I'm trying to do here, but I see it as just being a faster version of Python that works for anything that doesn't rely on C libraries. Since I'm working on pure Python libraries and many libraries in PyPi are written in pure Python, I don't see why I wouldn't be able to achieve what I'm trying to do here.

    Seems like conda create -n pypy3 -c conda-forge pypy3.5 would work. You're trying to give a version for the python package, which conda doesn't know what to do with

  • Thanks for the command @darthbith. It does create an environment with PyPy into it BUT it doesn't help here since I have to specify pypy3 instead of Python and pip install packages but those are not seen by my PyPy. While I understand my question is ambiguous, I'm basically trying to get PyPy to be seen as a regular version of Python. I want to do this because PyPy should work with most pure Python packages. I'd like to be able to use it when I don't do anything fancy basically. I'll edit my question to make that clearer.

Klassifikation nach ICD-10 A50 Syphilis connata A51 Frühsyphilis A52 Spätsyphilis A53 Sonstige und nicht näher bezeichnete Syphilis ICD-10 online (WHO-Version 2019) Syphilis , [1] auch Lues (venerea) , harter Schanker oder Franzosenkrankheit (maladie française) genannt, ist eine chronische Infektionskrankheit, die zur Gruppe der sexuell übertragbaren Erkrankungen gehört. Der Erreger der Syphilis ist das Bakterium Treponema pallidum ssp. pallidum . Die Syphilis wird hauptsächlich bei sexuellen Handlungen durch Schleimhautkontakt und ausschließlich von Mensch zu Mensch übertragen. Während der Schwangerschaft und bei der Geburt kann eine erkrankte Mutter ihr Kind infizieren ( Syphilis connata ). Das Erscheinungsbild der Krankheit ist vielfältig. Typisch ist ein Beginn mit schmerzlosen Schleimhautgeschwüren und Lymphknotenschwellungen. Bei einem Teil der Infizierten kommt es zu einem chronischen Verlauf, der durch vielfältigen Haut- und Organbefall gekennzeichnet ist. Im Endstadium kom
