I want to configure Sublime Text 3 to build Python 3, but I don\'t seem to understand how the builds work. Many tutorials have told me to make a build file containing code s
The reason you're getting the error is that you have a Unix-style path to the python executable, when you're running Windows. Change /usr/bin/python3 to C:/Python32/python.exe (make sure you use the forward slashes / and not Windows-style back slashes \). Once you make this change, you should be all set.
Also, you need to change the single quotes ' to double quotes " like so:
{
"cmd": ["c:/Python32/python.exe", "-u", "$file"],
"file_regex": "^[ ]*File \"(...*?)\", line ([0-9]*)",
"selector": "source.python"
}
The .sublime-build file needs to be valid JSON, which requires strings be wrapped in double quotes, not single.
