有个报错，不知道怎么处理

请按照issue的模板提问。

一般你直接使用python执行这个脚本报错的话，会提示这个错误。有可能是一些库或语法错误。
另外，检查一下burpy版本和python版本。

Describe the bug
在burpsuite 的Burpy 图形界面点击start server 按钮后会报错，Failed to get python file, pls recheck

经过排查好像是burpyServicePyro.py 脚本接收不到 sys.argv[-1]这个参数，burpyServicePyro.py 是不是安装burpy 时产生的

To Reproduce
Steps to reproduce the behavior:

1. 打开burpsuite
2. 在extensions 共add Burpy jar 包，直接在您github上下载的打包好的 。完成后burp 多了一个burpy模块
3. 在burpy 中输入python.exe和python脚本的 绝对路径，python 脚本是https://raw.githubusercontent.com/yearnwang/Burpy_web_decode/master/ex.py
4. See error :Failed to get python file, pls recheck

Expected behavior
A clear and concise description of what you expected to happen.

If applicable, add screenshots to help explain your problem.

Desktop (please complete the following information):

• OS: [win10 64位]
• Python: [python3.9.1]
• Burpy: [v2.4.3]

你直接使用python执行你要加载的脚本，也就是https://raw.githubusercontent.com/yearnwang/Burpy_web_decode/master/ex.py这个，如果能正常执行，才会正常加载。

burpyService这个脚本不需要拿出来，一般不会是这里的问题。

另外，ex.py应该是老版本的burpy使用的脚本，里面是python2的语法，你应该根据情况调整一下再运行。建议使用README里面的示例试一下。
