Locust failed to launch if installed from latest revision

Describe the bug

Locust failed to launch if being installed from the latest master commit (b2721592075676b87f62923b3936161619c230ec). Previous revision works just fine (3db9724d765b5f7b15e472f164e4d5e131bca14f).

Expected behavior

Correct launch

Actual behavior

  File ".../python3.9/site-packages/locust/user/users.py", line 108, in User
    environment: Environment = None
NameError: name 'Environment' is not defined

Steps to reproduce

1. Install locust from b2721592075676b87f62923b3936161619c230ec revision
2. Run simple test (locustfile.py):

from locust import HttpUser, task, constant


class TestUser(HttpUser):
    host = "https://google.com"
    wait_time = constant(1)

    @task
    def test_query(self):
        self.client.get("/search?q=test")

Environment

• OS: macOS 10.15.7
• Python version: 3.9.0
• Locust version: 1.4.1 (b2721592075676b87f62923b3936161619c230ec)
• Locust command line that you ran: locust --headless -u 1 -r 1 --run-time 5s

Good! Marking as invalid because it was never in a release…
