Conda: newer version of conda exists run "..."

Does anyone else here have the following problem?

using Conda; Conda.update();

INFO: Recompiling stale cache file C:\Users\Ilja\.julia\lib\v0.6\Conda.ji for module Conda.
Solving environment: ...working... 

# All requested packages already installed.

==> WARNING: A newer version of conda exists. <==
  current version: 4.4.2
  latest version: 4.4.6

Please update conda by running

    $ conda update -n base conda

However, when I run conda update -n base conda in the PowerShell, I get the following message:

CondaEnvironmentNotFoundError: Could not find environment: base .

Running Conda.runconda(`update -y conda`) solved the problem.
