Could someone please help me repair my anaconda so that I can use spyder? My pycharm app is acting up too. I'm really new to programing so I really appreciate the help. Thank you!

Hi Sydney,

I'd suggest re-installing Anaconda - it'll probably be the easiest solution for you.

Hi Sydney,

As already suggested ,re-install anaconda but don't  forget to check the box 'add to path'.  Anaconda suggested it should be unchecked, if you did so,then you need to add to path two things :

1. The python executable file ( python.exe) . 

2. The conda executable file (conda.exe) 

So check the thread on how to add these to path or reinstall anaconda and check the box ,'add to path'

Please do not add to path. It is not the correct way. Run the Anaconda Prompt instead.

But the reporter is using macOS anyway. They're you need to source the activate script:

source <install-location>/bin/activate
