Interesting... running "easy_install kicost" scans for yattag, finds v1.5.2, installs it, scans for lxml, finds v3.5.0, installs it, then says this:
Building lxml version 3.5.0.
Building without Cython.
ERROR: b"'xslt-config' is not recognized as an internal or external command,\r\n
operable program or batch file.\r\n"
** make sure the development packages of libxml2 and libxslt are installed **
Using build configuration of libxslt
error: Setup script exited with error: Unable to find vcvarsall.bat
Trying to run kicost results in almost the same as previous, but finishes with:
So it looks like lxml isn't functional, due to components libxml2 and libxslt not being installed. Okay, so the issue definitely seems to be lxml. Googling it, returns a StackExchange question about it, which essentially points to manually installing a lxml v3.5.0 binary. Note Python 2.6 or 2.7 is mandatory; I have 2.7.9 and 3.4.2 both but think 3 is default. Downloaded the executable, installed it, it demands to be installed in the 2.7 folder. Fine, no errors. Try "easy-install kicost" again, same lxml error. So it is trying to install lxml into 3.4.2 Python, which isn't working.
"python" executes v3. "py" executes v2... interesting. Googling how to switch between these, a large number of workarounds exist, all of which are rather customized and detailed. Adding PY_PYTHON = 2 env var did nothing.
Uninstalled Python 3.4.2, which uninstalled pip and setuptools...
Now "py" gives 2.7.9, but "python" does nothing. Added C:\Python27_64 to path. Now "python" is working.
NOW tried easy_install kicost, "easy_install" not a recognized command...
Okay here we go... uninstall all of the python versions (2.7.9 x32, 2.7.9 x64). Install JUST 2.7.11 x64 into cleaned-out c:\python27... add to the path, verify working with "python" and "py", but "easy_install" and "pip" do nothing...
Which according to this question, python's "scripts" folder also needs to be in the path. Looking in there, sure enough, pip.exe and easy_install.exe are there. So added, did the "easy_install kicost" without error, and "kicost --version" returns:
So it was a python configuration/compatibility issue. Decided to post this in case anyone else ran into these issues and need some guidance in what to try. But to be honest, the configuration may be beyond many users.
