我尝试使用 startButton = driver.find_element(By.CLASS_NAME, "start is-armed") 按类查找元素，但收到一条非常奇怪的错误消息。最后看起来几乎可以是汇编语言:
[23248:27252:0126/162232.236:ERROR:device_event_log_impl.cc(215)] [16:22:32.235] USB: usb_service_win.cc:415 Could not read device interface GUIDs: The system cannot find the file specified. (0x2)

有人知道为什么会发生这种情况吗？
最佳答案
By.CLASS_NAME 始终接受单个类值，而不是多个类值。
请使用 css 选择器。
startButton = driver.find_element(By.CSS_SELECTOR, ".start.is-armed")
