Short answer: You can’t, as far as I know. It wouldn’t really work either, right? If you use pyenv virtualenv to install a virtualenv into a repo, and you clone that repo to another machine… how would pyenv on the new machine know to take control of the virtualenv in the repository? Also, “you probably shouldn’t … Read more
i have had the same problem. and what i did is just run the command virtualenv env again. And then more files were generated under directory env/bin, including the activate file. it’s so weird.
setenv must be in [testenv]: [tox] envlist = py35 [testenv] deps=pytest commands=py.test setenv = XYZ = 123
Use the activate script in the Scripts directory of your virtual environment: > venv\Scripts\activate This will activate your virtual environment and your terminal will look like this depending on the directory you’re in: (venv) C:\Users\acer\Desktop> I hope this helps!
For me it works when I do these steps: Go to the directory/folder that you want run virtualenv .env then run source .env/bin/activate
This question was already addressed here, but without a real explanation on the role of prefix. At least there is a solution to exclude the prefix line programmatically. It is not mentioned in the conda doc, except for the fact that conda env export –prefix PATH allows to specify a prefix. But note that –name … Read more
Here is how you can switch to 3.9.0 for a given virtual environement venv-name: pip freeze > requirements-lock.txt pyenv virtualenv-delete venv-name pyenv install -s 3.9.0 pyenv virtualenv 3.9.0 venv-name pyenv activate venv-name pip install -r requirements-lock.txt Once everything works correctly you can safely remove the temporary requirements lock file: rm requirements-lock.txt Note that using pip … Read more
A couple possibilities occur to me: 1. A Potential Path Problem Your python command might refer to a different python than the python which is in your active conda environment folder. Check this by running in terminal which conda and which python. If you get something like the below, you’re good here. /anaconda3/bin/conda /anaconda3/envs/<yourEnvName>/bin/python If … Read more
I’m not sure if that solution matches the problem, but after installing pyenv, pyenv-virtualenv and selecting a python version, I had to run pip that way: $ pyenv exec pip install
Alright, I figured the problem. A little embarrassingly, I had not run pyenv shell 3.8.1 before running any of the other commands. Everything works now. Thank you all for your efforts.
