PyCrypto Refuses To Install

[gudenau]

I have been trying to install PyCrypto for the entire day, but failing.

pip install pycrypto fails with this:

Any idea how to fix this?

What version of Python are you using, and why is it trying to read from D:?

3.6, because it is my HDD.

So you have two Program Files directories on two different hard drives/partitions? Meh, anyway, try using 2.7.2.

I do not want to downgrade for pyCrypto, I can shell out for openSSL for now.

You don't have to "downgrade". You can have multiple versions of Python installed. You just call it with python2 or whatever the Windows equivalent is.

python2 pip install pycrypto

The Windows version is python, two installs can not easily coexist.

Yes they can. You just have to make sure your PATH directive stays consistent. This applies to all operating systems, not just Windows. Python versions install themselves to their own directories, and create a unique PATH directive for each installation, so it really isn't anything more than a ten second hassle to update your PATH.

Except for the part where they are all python.exe.

They're not. Each Python executable is appended with their version number (python27.exe, python36.exe, etc.), and your PATH is what makes it possible to call it as just "python". By doing so though, you're calling the latest version that's installed (until you change your PATH). This is why you have to specify the version either in the command or the script you're using.

I don't see python27/python35 either :/

Why is it using MSVC? :/ I think it would be a better idea to compile with gcc. Google how to switch your default PyDist compiler to MinGW

Oh ok, they changed it on Windows. Regardless, your PATH can be modified to specify Python 2 and 3's locations respectively. This will allow you to call them as either python2 or python3 (or whatever you set in your PATH).

I still do not understand how that would work, the PATH is only "look here for executables", has nothing to do with the name of the executable.

You have to create aliases. Welcome to the world of development environments.
