question:

I downloaded Microsoft Visual C++ Compiler for Python 2.7 , and install it, the full path of vcvarsall.bat is:

C:\Users\UserName\AppData\Local\Programs\Common\Microsoft\Visual C++ for Python\9.0\vcvarsall.bat

1	C:\Users\UserName\AppData\Local\Programs\Common\Microsoft\Visual C++ for Python\9.0\vcvarsall.bat

But the following code can’t return the path of it:

from distutils import msvc9compiler msvc9compiler.find_vcvarsall(9.0)

1 2	from distutils import msvc9compiler msvc9compiler.find_vcvarsall(9.0)

The installer doesn’t write the install information to the registry, and from the source code of find_vcvarsall(), it seems that it can’t find the vcvarsall.bat file from VS90COMNTOOLS setting, because it requires that the name of the folder that contains vcvarsall.bat is VC:

productdir = os.path.join(toolsdir, os.pardir, os.pardir, "VC")

1	productdir = os.path.join(toolsdir, os.pardir, os.pardir, "VC")

How can I use the compiler without modify registry or folder name?

best answer:

Update setuptools to 6.0 or greater. In those version setuptools can autodetect Microsoft Visual C++ Compiler for Python 2.7 with the vcvarsall.bat.
