ZSH: command not found: python

ZSH: command not found: python

If you get the "zsh: command not found: python" error message, it means that the python command is not available in your current shell. This can happen for a few different reasons.

One possible reason is that you don't have the python binary installed on your system. To fix this, you will need to install python. If you're not sure how to do this, you can search online for instructions on how to install python on your operating system.

Another possible reason is that the python binary is installed but not in a directory that's included in your shell's PATH environment variable. The PATH variable is a list of directories that the shell searches for executables. If the python binary is not in one of the directories listed in PATH, you will get the "command not found" error message.

You can try adding the directory where the python binary is installed to your PATH variable to fix this issue. The exact steps for doing this will depend on your operating system and the shell you're using. You can search online for instructions on how to edit the PATH variable for your specific setup.

It's also possible that you have multiple versions of python installed on your system, and the version you're trying to run is not the default. In this case, you can try running the python binary with the full path to the binary, or you can try using the which command to find the location of the binary. For example, you might run something like this:

which python

This will print the full path to the python binary that will be used when you run the python command. You can then use this full path to run the binary explicitly, like this:

/path/to/python my_script.py

Alternatively, you can use the alias command to create an alias for the python binary. For example, you might run something like this:

alias python='/path/to/python'

This will create an alias called python that points to the python binary at the specified path. You can then use this alias to run the binary, like this:

python my_script.py

How to install Python

To install Python, follow these steps:

  1. Visit the official Python website at https://www.python.org/

  2. Click on the "Download" button to download the latest version of Python.

  3. Once the download is complete, run the Python installer.

  4. Follow the instructions on the screen to complete the installation.

  5. Once the installation is complete, you can verify that Python is installed correctly by opening a command prompt or terminal window and typing the following command:

python --version

This should print the version of Python that is installed on your system. If you see a version number printed, it means that Python is installed and ready to use.

It's also good to check if the pip package manager is installed. pip is a tool that makes it easy to install and manage Python packages, and it is included with the most recent versions of Python. To check if pip is installed, run the following command:

pip --version

If pip is installed, you should see the version number printed. If you don't see a version number, you can try installing pip by running the following command:

python -m ensurepip --upgrade

This should install pip and make it available on your system.
