Can I install julia on anaconda without creating new environment?

I am an Ubuntu user, I have anaconda py3, I want to install julia form conda-forge channel, but when installing it using the following

conda indstall -c conda-forge julia

It tells me that some of the packages are gonna upgraded, I am afraid that it may cause a conflict with py3.

I know I can create an environment for julia using

conda create -n julia -c conda-forge julia

but I want to know I there is any one know what it will cost to not create a separate environment for julia

Answer

I found I can, but firstly I need to add conda-forge to channels

conda config --append conda-forge
conda config --set channel_priority true

conda install julia

In this way I don’t have to create a new environment, or cause any conflict between the default channel and conda-forge channel
