gdspy installation problem

Hello developer, I just tried to install the gdspy in py27 environment. However, I can’t install the package due to lack of visual c++ 9.0 compiler. It is ok to install in py38 environment. I searched whole day for any way to install the 9.0 compiler. However, I didn’t find any useful way. Do you have any experience for this problem. Here is my error information:

(py27env) C:\WINDOWS\system32>pip install gdspy
DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7. More details about Python 2 support in pip, can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support

Looks like only python 3 is supported by the conda package. You’ll either need to upgrade to >3.6 or get it to install via pip/ the binary on python 2.7
