title: Conda fails to install flask-bootstrap
body: <p>Conda refuses to carry out conda install flask-bootstrap. I have miniconda. Restarting my computer didn't help. I don't really know what else is pertinent but ill be around to respond if more info is needed. I don't know what else to say here bbut stackexchange needs me to add some more details so here. </p>
  
  <p>Ive tried updating conda and degrading conda to 4.6.11. I tried it on my base environment and it doesnt seem to work there either.</p>
  
  <p>My packages: </p>

  UnsatisfiableError: The following specifications were found
  to be incompatible with the existing python installation in your environment:
  
    - flask-bootstrap -&gt; python[version='2.7.*,3.5.*,&gt;=3.5,&lt;3.6.0a0']
  
  If python is on the left-most side of the chain, that's the version you've asked for.
  When python appears to the right, that indicates that the thing on the left is somehow
  not available for the python version you are constrained to.  Your current python version
  is (python=3.7).  Note that conda will not change your python version to a different minor version
  unless you explicitly specify that.
