TypeError: When i run a locustfile.py

Question

我的问题是我第一次尝试使用 Locust，我从他们的网站上复制了基本代码 https://docs.locust.io/en/stable/quickstart.html

这是他们给的代码

from locust import HttpUser, task, between
import random

class WebsiteUser(HttpUser):
    wait_time = between(5, 9)

    @task(2)
    def index(self):
        self.client.get("/")
        self.client.get("/ajax-notifications/")

    @task(1)
    def view_post(self):
        post_id = random.randint(1, 10000)
        self.client.get("/post?id=%i" % post_id, name="/post?id=[post-id]")

    def on_start(self):
        """ on_start is called when a User starts before any task is scheduled """
        self.login()

    def login(self):
        self.client.post("/login", {"username":"ellen_key", "password":"education"})

这是我的 locustfile.py

的路径

E:\work\wipro\work\locust_training\locustfile.py

至运行 locustfile.py 我在终端输入 locust

E:\work\wipro\work\locust_training>locust

它抛出的错误是

我搜索了相同的内容，但找不到任何具体的解决方案我什至尝试复制我能够找到的任何蝗虫代码，但这也没有帮助，因为在某种程度上这个错误出现或其他一些

有人可以帮忙吗

接下来我该做什么

任何帮助将不胜感激

提前致谢

Answer 1

好吧，我想如果其他人遇到这个错误，你可以试试这个：我将已安装的所有库更新为最新版本您可以使用以下代码来执行此操作，之后它对我有用，也许对您也有用

import pkg_resources
from subprocess import call

packages = [dist.project_name for dist in pkg_resources.working_set]
call("pip install --upgrade " + ' '.join(packages), shell=True)

祝你好运

Answer 2

我怀疑问题是蝗虫的要求没有指定最新版本的烧瓶（或者可能是它的依赖项，Werkzeug）。因此，如果您碰巧安装了旧版本（但足够新，可以满足 locust 的依赖性），locust 会尝试使用它但会失败。

我们现在已经更新了这个依赖项（在 Locust 1.0.2 中），所以希望这不会再发生在任何人身上。
