Linux     conda env export --no-builds   grep -v  prefix    environment yml  Windows     conda env export --no-builds   findstr -v  prefix    environment yml      Rationale  By default  conda env export includes the build information     conda env export     dependencies    - backcall 0 1 0 py37 0   - blas 1 0 mkl   - boto 2 49 0 py 0       You can instead export your environment without build info     conda env export --no-builds     dependencies    - backcall 0 1 0   - blas 1 0   - boto 2 49 0       Which unties the environment from the Python version and OS

I find exporting the packages in string format only is more portable than exporting the whole conda environment  As the previous answer already suggested     conda list -e  gt  requirements txt   However  this requirements txt contains build numbers which are not portable between operating systems  e g  between Mac and Ubuntu  In conda env export we have the option --no-builds but not with conda list -e  so we can remove the build number by issuing the following command     sed -i -E  s                  1   requirements txt    And recreate the environment on another computer   conda create -n recreated env --file requirements txt

I can t find anything in the conda specs which allow you to export an environment file without the prefix      line  However  as Alex pointed out in the comments  conda doesn t seem to care about the prefix line when creating an environment from file    With that in mind  if you want the other user to have no knowledge of your default install path  you can remove the prefix line with grep before writing to environment yml   conda env export   grep -v   prefix     gt  environment yml   Either way  the other user then runs   conda env create -f environment yml   and the environment will get installed in their default conda environment path   If you want to specify a different install path than the default for your system  not related to  prefix  in the environment yml   just use the -p flag followed by the required path   conda env create -f environment yml -p  home user anaconda3 envs env name   Note that Conda recommends creating the environment yml by hand  which is especially important if you are wanting to share your environment across platforms  Windows Linux Mac   In this case  you can just leave out the prefix line

The easiest way to save the packages from an environment to be installed in another computer is    conda list -e  gt  req txt  then you can install the environment using   conda create -n  lt environment-name gt  --file req txt  if you use pip  please use the following commands  reference https   pip pypa io en stable reference pip freeze    env1 bin pip freeze  gt  requirements txt   env2 bin pip install -r requirements txt
