I m using Conda on Windows and this answer did not work for me  But I can suggest another solution   rename enviroment folder  old name to new name   open shell and activate env with custom folder  conda bat activate  quot C  Users USER NAME Miniconda3 envs new name quot   now you can use this enviroment  but it s not on the enviroment list  Update install remove any package to fix it  For example  update numpy  conda update numpy  after applying any action to package  the environment will show in env list  To check this  type  conda env list

You can rename your Conda env by just renaming the env folder  Here is the proof   You can find your Conda env folder inside of C  ProgramData Anaconda3 envs or you can enter conda env list to see the list of conda envs and its location

You can t   One workaround is to create clone environment  and then remove original one    remember about deactivating current environment with deactivate on Windows and source deactivate on macOS Linux   conda create --name new name --clone old name conda remove --name old name --all   or its alias   conda env remove --name old name    There are several drawbacks of this method    it redownloads packages - you can use --offline flag to disable it  time consumed on copying environment s files  temporary double disk usage    There is an open issue requesting this feature

conda should have given us a simple tool like cond env rename  lt old gt   lt new gt  but it hasn t  Simply renaming the directory  as in this previous answer  of course  breaks the hardcoded hashbangs      Hence  we need to go one more level deeper to achieve what we want  conda env list   conda environments    base                      home tgowda miniconda3 junkdetect                home tgowda miniconda3 envs junkdetect rtg                       home tgowda miniconda3 envs rtg  Here I am trying to rename rtg -- gt  unsup   please bear with those names  this is my real use case    cd  home tgowda miniconda3 envs    OLD rtg   NEW unsup   mv  OLD  NEW     rename dir    conda env list   conda environments    base                      home tgowda miniconda3 junkdetect                home tgowda miniconda3 envs junkdetect unsup                     home tgowda miniconda3 envs unsup     conda activate  NEW   which python    home tgowda miniconda3 envs unsup bin python  the previous answer reported upto this  but wait  we are not done yet  the pending task is    NEW bin dir has a bunch of executable scripts with hashbangs      pointing to the  OLD env paths  See jupyter  for example    which jupyter  home tgowda miniconda3 envs unsup bin jupyter    head -1   which jupyter    its hashbang is still looking at old    home tgowda miniconda3 envs rtg bin python  So  we can easily fix it with a sed   sed  -i bak  quot s envs  OLD bin envs  NEW bin  quot   NEW bin        -i bak  created backups  to be safe    head -1   which jupyter    check if updated    home tgowda miniconda3 envs unsup bin python   jupyter --version   check if it works jupyter core       4 6 3 jupyter-notebook   6 0 3    rm  NEW bin   bak    remove backups   Now we are done  I think it should be trivial to write a portable script to do all those and bind it to conda env rename old new   I tested this on ubuntu  For whatever unforseen reasons  if things break and you wish to revert the above changes    mv  NEW   OLD   sed  -i bak  quot s envs  NEW bin envs  OLD bin  quot   OLD bin

Based upon dwanderson s helpful comment  I was able to do this in a Bash one-liner   conda create --name envpython2 --file  lt  conda list -n env1 -e     My badly named env was  env1  and the new one I wish to clone from it is  envpython2
