I have tried to install Spyder and Jupyter notebook using Terminal on my macOs (Mojave) but I am keep getting error:

/usr/local/bin/pip3: bad interpreter: /usr/local/opt/python@3.9/bin/python3.9: no such file or directory

I have installed Python 3.8.4 and it works on my MacBook but not on my desktop. I have tried to define a path in my bash file but without a success.

Usually when Python is not installed properly this happens.

In Mac, open a terminal and try the following commands

  1. which python
  2. which python3

This commands will check for python and let you know the path where Python2 and Python3 are present in the system.

For me, I got one output as /usr/bin/python which means I have python installed.

Now, I know python is installed and where is it installed. From here I can install jupyter.

/usr/bin/python -m pip install -U jupyter

Syntax is <python_locatoin>. -m pip install -U <package_name>

Note: If you are new, one simple way you can check for Anaconda Python and using Anaconda Python3 for your Python, Web Developer, ML and all other works. It has UI, to install Jupyter or Spyder and other

  • Tried to install Spyder and Jupyter as suggested. I get "requirement already satisfied", but cannot run it from terminal as before. I wanted to avoid Anaconda since one of the package I am using does not work properly. – vjagodnik Dec 27 '20 at 12:07
  • For Jupyter, after installing it. Type `jupyter notebook` in the terminal – sam Dec 27 '20 at 16:47
  • For some reason, Jupyter is now working. No luck with Spyder – vjagodnik Dec 27 '20 at 17:02
