pants depends on HOME env variable

[neutrinus]

I've created a pex file with pants (0.0.13). When I try to run it via supervisord(3.0b2-1), there is a problem with _pex_info.install_cache:

My supervisord config:

[program:wh_collector]
command=/home/whcollector/collector.pex
autorestart=true
startsecs=20
stopasgroup=true
killasgroup=true
user=whcollector
group=whcollector
stdout_logfile=/home/whcollector/logs/stdout
stderr_logfile=/home/whcollector/logs/stderr
directory=/home/whcollector/
environment=PEX_FOCE_LOCAL="1", PANTS_DEV=1, PEX_VERBOSE=10, 

When I add a HOME to environment it works like a charm.
