Hi, I notice that this buildbot is failing because it cannot find vcvarsall.bat https://buildbot.twistedmatrix.com/builders/windows7-64-py3.5/builds/174/ste... I was able to get a Windows 10 environment going by doing the following: (1) Installing Python 3.5 from https://www.python.org/downloads/windows/ (2) Install the exact Microsoft compiler version specified in: https://wiki.python.org/moin/WindowsCompilers (3) Ran this command to put CL.EXE in PATH: "C:\Program Files (x86)\Microsoft Visual C++ Build Tools\vcbuildtools.bat" (4) Ran these commands to put Python in PATH: set PYTHON_ROOT=C:\Users\Craig\AppData\Local\Programs\Python\Python35 set PATH=%PYTHON_ROOT%;%PYTHON_ROOT%\Scripts;%PYTHON_ROOT%\Tools\Scripts;%PATH% At this point, I was able to checkout Twisted from git and do python setup.py build python setup.py install Can we fix this buildbot at least to the point where we can do that? Thanks. -- Craig
