Keep getting "operation not permited" Erorr when running terminal commands

You need to be careful with your PATH settings if you have Apple's Xcode, or Command-Line tools installed, because not only do they install /usr/bin/python3, but also /usr/bin/pip3. Alternatively, a Python3 installed via Python.org's installers places soft links in /usr/local/bin for python3 and pip3 that are linked back to /Library/Frameworks/Python.framework/Versions/3.8/bin.

Without altering your PATH to access the pip3 command in /usr/local/bin, your defaulting to /usr/bin/pip3 will attempt to install the currencyconverter module into Apple's Python3 system library location, and that will fail. Once you have adjusted your PATH to access /usr/local/bin before /usr/bin, then the pip3 install -U currencyconverter command should succeed as the module will be written into /Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages.

Whenever I run commands such as pip3 or other commands in the terminal, I get a "Operation Not permitted" error. Here is an example:

and homebrew never seems to work for me, always different errors like:

brew install python3

Error: Cannot install in Homebrew on ARM processor in Intel default prefix (/usr/local)!

brew install pip3

Error: No formulae found in taps.

This tells you that you must install it differently on an M1 Mac. Check the Homebrew website for details on how to properly install Homebrew on an M1 Mac and how to install pip3 and/or Python on an M1 Mac.

Keep in mind if you are using an M1 Mac, then not everything in Homebrew may be fully compatible with an M1 Mac. You need to check the Homebrew website for compatibility information on the packages you wish to install.

Using the Zsh (~/.zshrc) or Bash (~/.bash_profile) dot files in your home directory, and your favorite text editor, you can alter the order of paths as I have shown below. The PATH statement on its own places /usr/bin before /usr/local bin and this is reversed below:

export PATH=".:$HOME/bin:/Library/Frameworks/Python.framework/Versions/3.10/bin:/usr/local/bin:${PATH}"

If you want that PATH to change in the current Terminal sessions, and not on the next Terminal launch, then do the following depending on your SHELL in use:

source ~/.zshrc
# or
source ~/.bash_profile

Are you on the administrator account or on an account with administrator privileges?

You are welcome.
