Question

我正在尝试通过pycharm在docker中运行气流。运行单元测试时，一切正常。但是，当我尝试执行cli命令时，似乎正在解释我的参数……很奇怪。

这是我通过pycharm在命令行中传递给气流的内容：

trigger_dag etl_pipeline --conf '{"client":"popsicle"}'

脚本路径指的是气流本身，因此这等效于调用：

airflow <above command>

当气流增加时，它会引发以下踪迹：

Traceback (most recent call last):
  File "/opt/.pycharm_helpers/pydev/pydevd.py", line 1668, in <module>
    main()
  File "/opt/.pycharm_helpers/pydev/pydevd.py", line 1662, in main
    globals = debugger.run(setup['file'], None, None, is_module)
  File "/opt/.pycharm_helpers/pydev/pydevd.py", line 1072, in run
    pydev_imports.execfile(file, globals, locals)  # execute the script

    execution_date=args.exec_date)

    return _default_decoder.decode(s)
  File "/usr/local/lib/python3.6/json/decoder.py", line 339, in decode
    obj, end = self.raw_decode(s, idx=_w(s, 0).end())
  File "/usr/local/lib/python3.6/json/decoder.py", line 357, in raw_decode
    raise JSONDecodeError("Expecting value", s, err.value) from None
json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

当我在中断点设置调试器时，我看到字符串看起来像这样：

s = {str} '\\'{client:quest_providence_health_services_2018_07_31}\\''

请注意，以上是pycharm呈现变量的方式。返回s将返回：

'\\'{client:quest_providence_health_services_2018_07_31}\\''

我敢肯定那里有太多的引号，但是我不清楚在命令行中只提供两个引号时为什么会有两组单引号。我尝试了完全不使用引号，但这只是给了我一个不同的解析错误。

引号需要转义：

test/perfdat/$HOSTNAME

pycharm运行命令无法正确转义
