[FIXED] IPython installed on Mac but ipython command is not found

Issue

I'm using MacOS and I recently installed anaconda, but it gives ipython - command not found when I want to check the version of ipython. It's not "a wrapper/launcher issue" which someone else in stackflow has asked about, since I could not find ipython in my directory. I've pasted the following commands in the terminal below. I hope that helps.

Solution

You need to create and activate a conda environment before you can use conda to install and use software. The conda documentation provides a step-by-step, but basically, the following shell commands are required:

# create environment
conda create --name myenv

# create an environment and install the ipython package into it
conda create --name myenv ipython

then activate the environment:

conda activate myenv

(By default, conda stores all environments in its own envs directory, but provides options for specifying custom directories for storing the environment.)

If you're not sure what environments you've already created, use conda info:

conda info --envs
