Fix substitution of “shell_cmd” on Mac OSX in Sublime Text 3 - sublimetext3

Question

I have a problem with my build system specified in project settings. Currently my project settings look like this
{
"build_systems":
[
{
"file_regex": "^[ ]*File \"(...*?)\", line ([0-9]*)",
"name": "Anaconda Python Builder",
"selector": "source.python",
"shell_cmd": "$project_path/bin/python -u $file"
}
],
"folders":
[
{
"file_exclude_patterns":
[
"pip-selfcheck.json",
"pyvenv.cfg"
],
"folder_exclude_patterns":
[
"lib",
"include",
"bin"
],
"follow_symlinks": true,
"path": "."
}
],
"settings":
{
"binary_file_patterns":
[
"*.jpg",
"*.jpeg",
"*.png",
"*.gif",
"*.ttf",
"*.tga",
"*.dds",
"*.ico",
"*.eot",
"*.pdf",
"*.swf",
"*.jar",
"*.zip",
"client/node_modules/**",
"data/**"
]
}
}
The actual problem problem is in the line:
"shell_cmd": "$project_path/bin/python -u $file"
Every time I close sublime and reopen it my shell_cmd gets substituted with this
"shell_cmd": "\"python\" -u \"$file\""
Which fails my build. Is there a way to fix this problem? What do I do to disable this automatic substitution?
Mac OS X 10.11.3

Answer 1

I already answered this question in the Anaconda's issues tracker but I will do it here for any other user that lands in this question with a similar problem.
That specific build system is used by Anaconda itself and that is why it is called "Anaconda Python Builder", it will update the "shell_cmd" with anything that you used as configuration for your "python_interpreter" setting into your anaconda's settings file (general, user or per project).
If you have specific needs for your build system, you should create a new build entry with your own options and stick to that one. Anaconda's build system is a convenience for users that need to use their configured Python interpreter instead of the embedded ST3 one.

I solved this issue without a custom build system by adding python_interpreter: 'full/path/to/python' to the settings dictionary. python part in the Anaconda Python Builder shell_cmd gets replaced with it.
