After I have run
anaconda-project add-packages python=3.5
there downloaded some dependencies. Where those downloading locate in? and How could I delete those files by anaconda command line?
If you had created a virtual environment, then you can find the location of the packages by
$ echo $VIRTUAL_ENV
The packages are stored inside lib/ directory. You can delete the files manually or use conda remove --force
The real problem here is, anaconda-project run under a installed env, it will install the absent packges in this env by default.
