在ubuntu18.04中运行OdooLocust

Question

我正在尝试使用OdooLocust模块执行负载测试。当我尝试运行时，出现以下错误：

命令如下：

 sudo locust -f seller_taskset.py Seller

Python版本：

 python -V

 Python 2.7.15rc1

Answer 1

在您的问题中，您展示了系统Python版本是2.7.15rc1，但是从堆栈跟踪中可以清楚地看到locust是用python3.6安装和运行的，通常用python3运行python2.7代码会导致语法错误，因为这两个版本的语法存在显著差异。你知道吗

您正在运行的特定脚本需要运行python2.7。安装python virtualenv，使用以下命令使用python2.7创建虚拟环境：

virtualenv -p python venv

安装要求：

./venv/bin/pip install -r requirements.txt

现在运行python脚本：

./venv/bin/locust -f seller_taskset.py Seller

还有你想和sudo一起跑蝗虫，我觉得没必要。
