来自两个不同 Linux 发行版的运行 python locust 脚本出错

Question

我写了一个 locust 脚本来测试网站。脚本很简单，就是一个请求重复几次。

在装有 Linux Mint 和 Python 2.7.6 的虚拟机中，脚本以正确的方式工作，正如我想要的那样。

例如，我运行没有Web界面的脚本如下：

locust --no-web -n 10 -c 1 -r 1 -f /path/to/file/file_test.py

并且我在终端中获得了正确的统计数据 window。

当我在另一台装有 CentOS 和 Python 2.7.11 的虚拟机上运行执行相同的脚本时，出现以下错误：

你能帮我理解这个问题吗？非常感谢。

这似乎是 urllib3 中的一个已知问题，与您的脚本无关。参见 https://github.com/shazow/urllib3/issues/482
