python3.7运行AndroidUiautomationPoco，报错：ImportError: sys.meta_path is None, Python is likely shutting down

运行代码如下：
poco = AndroidUiautomationPoco(use_airtest_input=True, screenshot_each_action=False)
aa = poco("android:id/switch_widget")
print(aa.attr("checked"))

在IDE(1.2.5)中用自带的python(应该是3.5吧)运行，正常
换成本地python3.7
可以运行，但最后报错（报错不影响运行）：
Exception ignored in:

--------------------------------
但如果调整运行代码为：
poco = AndroidUiautomationPoco(use_airtest_input=True, screenshot_each_action=False)
poco("android:id/switch_widget")
print(poco("android:id/switch_widget").attr("checked"))

即，不把poco实例赋值给变量，python3.5，3.7都运行正常，不报错
