Usually this error, "PackageNotInstalledError: Package is not installed in prefix." is because your custom environment doesn't have the conda infrastructure. Instead, it is in your base only. To update the base environment: conda update --name base conda To see what version you have installed: conda list --name base conda example output of list; # packages in environment at /Users/me/miniconda2: # # Name Version Build Channel conda 4.6.14 py27_0 conda-env 2.6.0 h36134e3_0
