unable to activate existing conda environments

Question

I have created a Conda environment in Pycharm called Practice using Python3.7. I am using a Mac and using the Pycharm terminal (fish) however i receive the same error using iterm2.

when i type conda activate Practice i receive the following error:

An unexpected error has occurred. Conda has prepared the above report.

i have already run conda init fish and restarted my shell and even tried restarting the machine and i'm still receiving the same error.

This issue is preventing me from running code because my project interpreter is configured to this environment but any time i try to install packages it installs to the active environment (base).

I had the same problem. Notice that /usr/local/anaconda3/bin is on your PATH twice. Make sure you aren't putting that directory on your path yourself.

The conda init fish adds a line to your fish configuration that will create a 'conda' shell function, and by appending /usr/local/anaconda3/bin to your PATH, you are interfering with some assumption that conda init makes.

Check your .bashrc or .zshrc config ,modify the conda path config correctly

eg :

vi .zshrc

then

# >>> conda initialize >>>
# !! Contents within this block are managed by 'conda init' !!
__conda_setup="$('/Users/mac/opt/anaconda3/bin/conda' 'shell.zsh' 'hook' 2> /dev/null)"
if [ $? -eq 0 ]; then
    eval "$__conda_setup"
else
    if [ -f "/Users/mac/opt/anaconda3/etc/profile.d/conda.sh" ]; then
        . "/Users/mac/opt/anaconda3/etc/profile.d/conda.sh"
    else
        export PATH="/Users/mac/opt/anaconda3/bin:$PATH"
    fi
fi
unset __conda_setup
# <<< conda initialize <<<

export PATH=/Users/mac/opt/anaconda3/bin:$PATH

chage /Users/mac/opt/anaconda3/bin to your own path

after change config , remember source your bashrc or zshrc file

source .zshrc

it works a lot , unless the conda path config conflict

I had the same issue . The path variable was incorrect . Type echo $PATH , you will be able to see the current path . I changed that to anaconda directory by executing the following command export PATH=/home/username/anaconda3/bin. This resolved my issue.
