Constantly there is an error in ST3 3103 (error: plugin_host), how to fix it?

Question

Sublime Text

Windows 10 x64, the following plugins are installed in the editor (ST3 Build 3103):
PackageControl, Emmet, BracketHighlighter, SublimeCodeIntel,SideBar.
Always at the beginning of a set in a file with the .php extension, an error window appears, when working with .html/.css/.js everything is fine.
Console output:
+ Info: processing `PHP': please wait...
Could not import subprocess32 module, falling back to subprocess module
error: plugin_host has exited unexpectedly, plugin functionality won't be available until Sublime Text has been restarted

Answer 1

what is the point of putting an early alpha if there is no understanding that it needs to be constantly updated, and after catching a bug, run not to the forum (where no one cares about this), but write to the developer.
That's the whole point of using early alpha versions, you know.
