回答1:
Assuming you want spyder2 for Python 2.7:
You need to install spyder for the Python version you want:
python -m pip install spyder
Then you just need to run it for that version. So:
python -m spyder

You can use pip to install it like follows
sudo pip install -Iv spyder==2.3.9
-I: reinstall (Ignore installed).v: verbose.
