I cannot install the library for python 3.7

[Prometheus1994]

After I published this issue 3 days ago #36. And I got a reply which I figure it means that I should try install it for python 3 instead. I uninstalled Python 2 and reinstalled Python 3 and I ran the command again with Anaconda Prompt (Because it doesn't work in Command Prompt) and the problem remains unsolved. This is what I get:

I'm not familiar with Anaconda, but the problem here is that setuptools is attempting to build pyEDA's C files from source using Visual C++, which is not installed on your machine. I recommend looking at https://www.lfd.uci.edu/~gohlke/pythonlibs/ for the Windows installation.

@cjdrake No, actually I have Visual C++ installed on my machine and I tried to install the library through "Visual C++ 2008 64-bit Command Prompt" and "Visual C++ 2008 64-bit Cross Tools Command Prompt" and this is what I got:

C:\WINDOWS\System32>pip install boolexpr
pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.

@cjdrake There is no boolexpr package in the link you sent me. And after I looked for boolexpr binaries on google, I found this page http://mirrors.aliyun.com/pypi/simple//boolexpr/ but I can't download any file from it neither installing it directly from a prompt !!

[cjdrake]

Ah, my mistake. I'm used to answering questions for PyEDA, and didn't realize I'm looking at the boolexpr repository.

The latest release was 2.4 (Sept 2016), located here. I compiled a few wheels for it, including a Windows 64-bit binary for Python 3.5. I'm guessing the problem is that Python 3.7 setuptools is ignoring the wheel built for 3.5.

The issue you saw with SSL looks like something different, and I've never seen it before.

Fortunately, it looks like someone else has seen it before: https://stackoverflow.com/questions/41328451/ssl-module-in-python-is-not-available-when-installing-package-with-pip3
