Circus environment variable reference

[CarlosEssun]

Environment

pyenv python==3.5.2 paho-mqtt==1.3.1 circus==1.3.0

Description

My own script file, which references paho-mqtt, runs without problems when using the command line.

• command line

  circusd --log-level debug /etc/circus/conf.d/mqtt.ini 

• circus.ini

  
  [circus]
  check_delay = 5
  endpoint = tcp://127.0.0.1:5555
  pubsub_endpoint = tcp://127.0.0.1:5556
  statsd = true
  logoutput= /var/log/sengled/circus/circus-stdout.log
  include = /etc/circus/conf.d/*.ini
  #httpd = True
  #httpd_host = 0.0.0.0
  #httpd_port = 8300
  [watcher:webapp]
  cmd = /opt/pyenv/shims/chaussette --fd $(circus.sockets.web)
  numprocesses = 3
  use_sockets = True

[socket:web] host = 0.0.0.0 port = 9999

* mqtt.ini

[watcher:mqtt] working_dir = /opt/sengled/reliabilityOps/Firmware/light/firmware cmd = python args = -u mqtt_service.py numprocesses = 1

copy_env = True

copy_path = True

virtulenv = /opt/pyenv/versions/firmware

stderr_stream.class = FileStream stdout_stream.class = FileStream stdout_stream.filename = /var/log/sengled/mqtt/mqtt-stdout.log stderr_stream.filename = /var/log/sengled/mqtt/mqtt-stderr.log stdout_stream.max_bytes = 1073741824

 but when I use the service reference watcher mqtt, I always find that I can't find it.
Traceback (most recent call last):
  File "mqtt_service.py", line 16, in <module>
    import paho.mqtt.client as mqtt
ImportError: No module named paho.mqtt.client
but I don't have this problem on the command line.
```bash

Other configuration file [ini] references have no such problem I think it may be an environmental path problem, but I did not find a specific solution! Thank you

I'm not sure to understand your problem, but I would say that you probably need to uncomment copy_env = True so that your process runs in the right virtualenv.

[CarlosEssun]

@k4nar Enable copy_env=True I got it. Thanks
