Xcode – FileNotFoundError: [Errno 2] No such file or directory: b'/Users/<myname>/Desktop/kivy/kivy-ios/dist/hostpython3/bin/pip3' ( kivy app )

Since I got this error when building project in Xcode,

ModuleNotFoundError: No module named 'requests'

and then I’m trying to install the requests module with git command.

python toolchain.py pip install requests

However, I read the logs and I got this FileNotFoundError message. How can I deal with the error?

So I looked the file "/Users//Desktop/kivy/kivy-ios/dist/hostpython3/bin/pip3" and the virtual environment file "/Users//Desktop/kivy/kivy-ios//lib/python3.9/site-packages/sh.py" to see whether they are existed. And both of them are really existed! I’m so confuse with this error. So please help me out here! It is the finally step for me to run my first app soon! Thanks!

    I have tried many ways to solve the issue in the last few days but failed. Finally, an admin in the kivy discord helps me solve the issue.

    In my case, maybe I used the command sudo toolchain.py build python kivy. However, sudo is bad, and maybe what caused this issue.

    After I clean up the build and reinstall all kivy using toolchain.py build python kivy, I finally solve the issue. Thank you for the help from the admin and kivy community!

    Let’s tackle this in steps:

    I’m making the assumption that your toolchain.py file is the script you would like to run, for which you need the requests module.

    Step 1: Activate your virtual environment (you have possibly already done this)

    Before installing a new module using pip install <module>, you want to activate your virtual environment, because you want to install it in there.

    You can do this by doing:

    • In linux: source <your-venv-path>/bin/activate
    • In windows: <your-venv-path>Scriptsactivate.bat

    Some good answers on how to activate a virtual environment can be found for Windows and for Linux.

    Step 2: Install the requests module

    Now your virtual environment is active, you should be able to install the requests module like this:

    pip install requests

    Step 3: Run your script

    After this, you should be able to run your script with the requests module installed like so:

    python toolchain.py
