From 03510ec4ce9cc21d4e5fcc91f23256f6f4431160 Mon Sep 17 00:00:00 2001 From: Toshio Kuratomi Date: Thu, 5 Jan 2017 15:11:23 -0800 Subject: [PATCH] Allow OSError to skip scriptdir removal On Ubuntu the scriptdir gets placed into sys.path. This makes some modules (copy) fail because the ansible module gets loaded instead of the stdlib copy module. So we remove scriptdir there. Unfortunately, the scriptdir code uses abspath(). When pipelining, abspath() has to find the cwd. On OSX, finding the cwd when that directory is not executable by the user raises an OSError. Since OSX does not suffer from the scriptdir problem we're able to just skip scriptdir handling if we get that exception.
