Error pip installing packages

hi, I try to install packages from requirements.txt in a virtualenv i created in a bash console, but it returns me an error :

(apenv) 14:09 ~ $ pip install -r requirements.txt                                                                                                                                                                   Looking in links: /usr/share/pip-wheels
Processing /opt/conda/conda-bld/bottleneck_1657175564434/work
ERROR: Could not install packages due to an OSError: [Errno 2] No such file or directory: '/opt/conda/conda-  bld/bottleneck_1657175564434/work'

How can i solve this issue? Thanks

What do you have in your requirements.txt?

Could you also post the contents of your requirements.txt?

Never mind. I fixed my issue. I had an extremely large requirements.txt file, created using pip freeze > requirements.txt, with many things that I think were unnecessary. I created a much smaller version using the pipreqs library, and now I was able to install everything in my new requirements.txt file as usual with pip install -r requirements.txt.

@anoack -- great, glad to hear that you got it working!

@Dataisbeautiful -- thanks for the details. Is the error you're getting exactly the same as the one that @anoack? If not, could you let us know what it is?

Hi, the posted error message is mine!

Ah, sorry! You're quire right, I misread.

How did you create the virtualenv that you're working in -- the one with the name apenv?

Staff giles | 11788 posts | PythonAnywhere staff | Dec. 30, 2022, 7:06 p.m. | permalink

i pip installed them one by one, only the ones not included in pythonanywhere.

Do you remember the command you run to create the virtual environment itself?

Staff pafk | 2973 posts | PythonAnywhere staff | Dec. 31, 2022, 10:37 a.m. | permalink

I used mkvirtualenv.
