This example illustrates the addition of anaconda3 for both append and prepend options. zshrc and add the necessary path to the new Python interpreter to the file. zshrc for such purpose.įor zsh you should run nano. Depends on whether you use bash or zsh, you should have to edit. You can always add the additional path to the $PATH variable to the beginning or the end, depending on your requirements. : is a separator of the path in such syntax and the order of these paths defines the order in which the system tries to find the python3 interpreter (for example) when you run python3 without specification of /usr/local/bin/python3. usr/ local/bin:/usr/bin:/bin:/usr/sbin:/sbin We can view the content of this variable by running: echo $PATH It means that the /usr/local/bin directory is included in the $PATH environment variable. Just a reminder, you can always type the full path to the Python interpreter and it will be the same as the shortcut name: python3.10Īnd now we came to an important part, how to understand why python3.10 was found in exact /usr/local/bin/python3.10 directory. Users/daniilkorbut/anaconda3/bin/python3.8 To see precisely the path to the Python interpreter that is used during the call (for my specific case): python, python3.8, etc. Python python3-config python3.8 python3.9-config python.app python3.10 python3.8-config pythonw python3 python3.10-config python3.9 There is nothing confusing at all! Whichįirst of all, to understand the number of possible Python versions installed on your Mac, you can simply check it in your bash console by running: python Let's dive deeper together into possible issues you may have and structure all the knowledge. Type 'help', 'copyright', 'credits' or 'license' for more information. You probably experienced the situation when you installed the Python package via pip and saw such an error during the validation of the successful installation: python

Sometimes it makes the usage of the specific version of Python, and alignment between installed packages and the pip version very confusing.

This can be done by using a version manager such as conda or using virtual environments with appropriate Python versions for each of your specific tasks. It is possible to have multiple versions of Python installed on a single MacBook.
