RobotFramework:pythonpath参数在使用api的run方法时不起作用

我试图运行官方的RF计算器示例，通过提到pythonpath参数来指向.py文件（CalculatorLibrary.py）

当我从命令行将pythonpath传递给pybot时，它就工作了

[centos6 tmp]$ pybot -t "Push multiple buttons" -t "Push button"  --pythonpath RobotDemo/ RobotDemo
==============================================================================
RobotDemo

==============================================================================

------------------------------------------------------------------------------

2 tests total, 2 passed, 0 failed
==============================================================================

但是，当我使用RunAPI执行此操作时，它不起作用

这是密码

import robot
abs_master_suite_path = "RobotDemo"
testcases_tobe_run_list = ["Push multiple buttons","Push button"]
this_path = ["RobotDemo"]
ret = robot.run(abs_master_suite_path,  test=testcases_tobe_run_list, pythonpath=this_path)

这是我得到的结果

[centos6 tmp]$ python run_pybot.py

RF无法找到给定的Python路径

在这种情况下，我是错了还是射频有问题？

“机器人”有两个功能来运行测试

run（）：运行测试的函数。

run_cli（）：使用命令行参数处理运行测试的函数。

在'Python27\Lib\site packages\robot\utils\application.py'中

    def execute_cli(self, cli_arguments):
    with self._logging():
        options, arguments = self._parse_arguments(cli_arguments)
        rc = self._execute(arguments, options)
    self._exit(rc)


    def execute(self, *arguments, **options):
    with self._logging():
        return self._execute(list(arguments), options)

'execute\u cli'调用'self.\u parse\u参数（cli\u参数），因此可以使用参数'pythonpath'。 “def parse_args”→ '_处理(特殊)选项" 方法“\u handle\u special\u options”调用

        if self._auto_pythonpath and opts.get('pythonpath'):
        sys.path = self._get_pythonpath(opts['pythonpath']) + sys.path

因此，您必须更新方法“def execute”

    def execute(self, *arguments, **options):
    with self._logging():
        if options['pythonpath']:
            sys.path=[options['pythonpath']]+sys.path
            del  options['pythonpath']       
        return self._execute(list(arguments), options)

最近也遇到了同样的问题。在点击robot.run API之前，您可以通过导入robot.pythonpath setter并调用add_path手动添加所需的pythonpath。但是，这可能会在程序中的其他地方导致意外的副作用，因此在测试运行完成后，您可能希望调用remove_path

例如：

通过RF用户组，我得到了官方确认，在使用pythonpath与robot.run时存在一些不一致，将在缺陷跟踪器中提出

from robot import pythonpathsetter
pythonpathsetter.add_path(additional_python_path)
robot.run(test_suite)
pythonpathsetter.remove_path(additional_python_path)
