Can't run test via locust command line

[anhvuong123]

Hi locustio and community,

I'm a newbie in Locust Performance test & very interested in the modern tool Locust.
Via the first round to start, I have just prepared some things but get a error after run locust:

1. Machine to run Locust Tool: Windows10
2. Installed Pyhton 3.6.2
3. Installed pip as the guide from https://pip.pypa.io/en/stable/installing
4. Installed newest Locust as the guide "pip install locustio" (run from command line)
5. Prepare the pyhton file with the example code as below:
   from locust import HttpLocust
   from tasks import MyTasks
   class UserBehavior(TaskSet):
   def on_start(self):
   """ on_start is called when a Locust start before any task is scheduled """
   class WebsiteUser(HttpLocust):
   task_set = UserBehavior
   min_wait = 5000
   max_wait = 9000
   host="http://localhost"
6. I open command line & run via the statement: locust -f "C:\Users\Administrator\Desktop\install Locustio\Example Code\ex1.py"

==> Actual Result: Get error from the current command line:
"Traceback (most recent call last):
File "C:\Program Files (x86)\Python3.6.2\Scripts\locust-script.py", line 11, in
load_entry_point('locustio==0.7.5', 'console_scripts', 'locust')()

from core import HttpLocust, Locust, TaskSet, task
ModuleNotFoundError: No module named 'core'
"

Please help me via the case & Let me know if you has a other way to help me start it with the better result.

Many thanks,

I believe this is an issue that has been fixed in the alpha which you must explicitly install:

pip install locustio==0.8a2

See #310

I have followed as you mention and it can run successfully.

Many thank andrewmichaelsmith,
