I am trying to install numpy library on Python 2.7.15 in PyCharm but the error message I get is:

ERROR: Could not find a version that satisfies the requirement numpy (from versions: none)
ERROR: No matching distribution found for numpy
c:python27libsite-packagespip_vendorurllib3utilssl_.py:164: InsecurePlatformWarning: A true SSLContext object is not available. This prevents urllib3 fro
m configuring SSL appropriately and may cause certain SSL connections to fail. You can upgrade to a newer version of Python to solve this. For more information, see https://urllib3.readthedocs.io/en/latest/advanced-usage.html#ssl-warnings
  InsecurePlatformWarning,

Any clues?
