[conda] Conda wants to downgrade me?

[Allan Kinnaird]

Having done a clean install of Python 3.7 from the Anaconda installer 5.3,
I find that

conda install pandas-datareader

or

conda update anaconda

want to revert me to Python 3.6, in spite of the fact that there are 3.7
versions of both packages available in the Anaconda channel.
I was thinking perhaps it's a dependency problem, but that doesn't make
sense since a 3.7 version of anaconda is already installed.
Ideas?

Does it work if you are explicit about the version of pandas-datareader you
want to install? Is it possible the Python version dependency for the 3.7
version of the package is stuck at 3.6?

Just a couple things which come to mind as possibilities ...

Try adding "python=3.7" to your conda install command:

conda install pandas-datareader python=3.7

For me, adding the explicit version of the package conda is changing
usually prompts a more meaningful conflict message. You may need to specify
the pandas-datareader version as well.

Thanks guys - the python=3.7 specification worked for pandas-datareader.
(The package is at v0.6.0 for both Python 3.6 and 3.7)
"conda update" doesn't want to accept the Python specification, so I
couldn't do the "condo update anaconda", but I'm not going to worry about
it.
