How I make pip see libgit2 binary while installing pygit2 in windows?

504 Views Asked by At

I'm trying to install pygit2 using pip python script, but it always fails with this message

error: Unable to find vcvarsall.bat

I don't have Visual Studio installed, so I tried to compile libgit2 using MinGW and it worked. but pip still cant figure that libgit2 is installed.

What am I supposed to do ?

EDIT

I installed Visual Studio express 2010 and run the command again, this time the error different :
