How to run Conda?

Question

you might want to try this:

for anaconda 2 :

export PATH=~/anaconda2/bin:$PATH

for anaconda 3 :

export PATH=~/anaconda3/bin:$PATH

for anaconda 4 :

Use the Anaconda Prompt

and then

conda --version

to confirm that it worked. The export PATH=~/anaconda3/bin:$PATH works but stops when you exit the terminal in order change that you have to run sudo nano ~/.bashrc and then copy the path into the file and save it after that you activate the changes using source .bashrc.

check with conda install anaconda-navigator if not installed follow the anaconda install instructions again

It turns out that I had not set the path.

To do so, I first had to edit .bash_profile (I downloaded it to my local desktop to do that, I do not know how to text edit a file from linux)

Then add this to .bash_profile:

PATH=$PATH:$HOME/anaconda/bin

Use conda init

As pointed out in a different answer, manually adding Conda on $PATH is no longer recommended as of v4.4.0 (see Release Notes). Furthermore, since Conda v4.6 new functionality to manage shell initialization via the conda init command was introduced. Hence, the updated recommendation is to run

Linux/UNIX (OS X < 10.15)

./anaconda3/bin/conda init

Mac OS X >= 10.15

./anaconda3/bin/conda init zsh

Windows

./anaconda3/Scripts/conda.exe init

You must launch a new shell or source your init file (e.g., source .bashrc) for the changes to take effect.

Details. For an in-depth look at exactly what conda init does see this answer.

Alternative shells

You may need to explicitly identify your shell to Conda. For example, if you run zsh (Mac OS X 10.15+ default) instead of bash then you would run

./anaconda3/bin/conda init zsh

Please see ./anaconda3/bin/conda init --help for a comprehensive list of supported shells.

Word of Caution

I'd recommend running the above command with a --dry-run|-d flag and a verbosity (-v) flag, in order to see exactly what it would do. If you don't already have a Conda-managed section in your shell run commands file (e.g., .bashrc), then this should appear like a straight-forward insertion of some new lines. If it isn't such a straightforward insertion, I'd recommend clearing any previous Conda sections from $PATH and the relevant shell initialization files (e.g., bashrc) first.

Again, for those interested, there is an in-depth look at how it works, in this answer.

Potential Automated Cleanup

Conda v4.6.9 introduced a --reverse flag that automates removing the changes that are inserted by conda init.

If you have installed Anaconda but are not able to load the correct versions of python and ipython, or if you see conda: command not found when trying to use conda, this may be an issue with your PATH environment variable. At the prompt, type:

export PATH=~/anaconda/bin:$PATH

For this example, it is assumed that Anaconda is installed in the default ~/anaconda location.
