json.decoder.JSONDecodeError in ChromeDriverManager().install()

Question

直到昨晚，当最后一次安装被尝试时，代码运行良好，我没有做任何更改。然后，当我再次运行我的程序时，我从终端得到了这个回溯：

<snip>
cd_service_obj = Service(ChromeDriverManager().install())
  File "C:\...\my_venv\lib\site-packages\webdriver_manager\chrome.py", line 39, in install  
    driver_path = self._get_driver_path(self.driver)
  File "C:\...\my_venv\lib\site-packages\webdriver_manager\core\manager.py", line 26, in _get_driver_path
    binary_path = self.driver_cache.find_driver(driver)
  File "C:\...\my_venv\lib\site-packages\webdriver_manager\core\driver_cache.py", line 101, 
in find_driver
    metadata = self.get_metadata()
  File "C:\...\my_venv\lib\site-packages\webdriver_manager\core\driver_cache.py", line 135, 
in get_metadata
    return json.load(outfile)
  File "C:\Users\myself\AppData\Local\Programs\Python\Python310\lib\json\__init__.py", line 293, in load
    return loads(fp.read(),
  File "C:\Users\myself\AppData\Local\Programs\Python\Python310\lib\json\__init__.py", line 346, in loads
    return _default_decoder.decode(s)
  File "C:\Users\myself\AppData\Local\Programs\Python\Python310\lib\json\decoder.py", line 337, in decode
    obj, end = self.raw_decode(s, idx=_w(s, 0).end())
  File "C:\Users\myself\AppData\Local\Programs\Python\Python310\lib\json\decoder.py", line 355, in raw_decode
    raise JSONDecodeError("Expecting value", s, err.value) from None
json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

我重建了整个虚拟环境，但仍然得到了这个错误。是什么引起的，我该怎么解决呢？

在出现更好的答案之前，我只是没有在Chrome()对象中包含Chrome()参数，并注释掉了创建Service()对象的代码行，并且“修复”了它。
