Recovering Your Anaconda Installation

Last Updated: Nov 21, 2017 05:03PM CST
If your Anaconda installation is in a state where normal conda commands are not functioning, use the following steps to repair Anaconda and preserve your installed packages and environments.

Step 1. 

Download a new installer, http://repo.continuum.io/archive/, then follow the instructions for your system Windows, macOS or Linux:


Windows

Change your original installer's name so you do not overwrite it:
move Anaconda Anaconda_old

Run the Anaconda .exe installer as usual and use robocopy to sync the directories:
robocopy Anaconda_old Anaconda /S
rd /s Anaconda_old

NOTE: Use the actual path, filename and directory name for your installation. 
When finished, go to Step 2.


macOS:

Change your original installer's name so you do not overwrite it:
mv anaconda anaconda_orig

Install to same directory as your original installer:
bash Anaconda3-4.0.0-MacOSX-x86_64.sh
rsync -a anaconda_orig/ anaconda/
rm -rf anaconda_orig

NOTE: Use the actual path, filename and directory name for your installation.
When finished, go to Step 2.


Linux:

Change your original installer's name so you do not overwrite it:

mv anaconda anaconda_orig

Install to same directory as your original installer:
bash Anaconda3-4.0.0-Linux-x86_64.sh
rsync -a anaconda_orig/ anaconda/

NOTE: Use the actual path, filename and directory name for your installation.
When finished, go to Step 2.

Step 2.

Run conda list to view the packages from the previous installation.

Run conda info -e to list the environments created in the previous installation which are now available in the new installation.
