Unable to Install Packages in PyCharm Community Edition

I am trying to install TensorFlow in PyCharm. I have Python 3.6. I tried this in the PyCharm Console------------------ pip.main(['install', 'tensorflow']) Collecting tensorflow Could not find a version that satisfies the requirement tensorflow (from versions: )

No matching distribution found for tensorflow

I also tried installing from a virtual environment, but it said: Collecting tensorflow

Could not find a version that satisfies the requirement tensorflow (from versions: ) No matching distribution found for tensorflow


How can I fix this issue? Thanks so much!! :D
