Expected behavior 正常运行脚本。怀疑是airtest和poco的环境配置问题，该脚本在另一台macOS上能运行成功。

python version: python3.7

airtest version: 1.0.26

You can get airtest version via pip freeze command.

Smartphone (please complete the following information):

• Device: iphone7 plus
• OS: iOS 11.3
• more information if have

I also had this issue. Was very odd since it worked fine on one mac but didn't work on another. Nonetheless I had to go into the poco driver class to patch things up.

If anyone's still having this problem, node["frame"] is returning a string since keys are not provided in that json data for some reason, (i.e. it looks something along the lines of this: "{{34, 67}, {337, 731}}"), and since it can't parse that into json data, it has to accept it as a string.

So a quick fix I set up was to grab the values out of the string manually, (if it is a string). Go into poco/drivers/ios/__init__.py, in the json_parser() method, replace:

w = float(node["frame"]["width"])
h = float(node["frame"]["height"])
x = float(node["frame"]["x"])
y = float(node["frame"]["y"])

with this instead:

from re import search

if isinstance(node["frame"], str):
     frameData = search(r'{{(-?\d+\.?\d*), (-?\d+\.?\d*)}, {(\d+\.?\d*), (\d+\.?\d*)}}', node["frame"])
     x = float(frameData.group(1))
     y = float(frameData.group(2))
     w = float(frameData.group(3))
     h = float(frameData.group(4))
else:
     w = float(node["frame"]["width"])
     h = float(node["frame"]["height"])
     x = float(node["frame"]["x"])
     y = float(node["frame"]["y"])

Things should work fine after that.

It did work for me in some cases. However, another error occurred:

So this means the regex is not matching in some cases. Can you add a print statement and log node["frame"] before that added code, so you can see what the frame data looks like before it runs into that error?

[IcyW]

I've tried to debug the program and figured out that when the errors, the structure of node is like:

However, if the program runs properly, it should be like:

I also had this issue. Was very odd since it worked fine on one mac but didn't work on another. Nonetheless I had to go into the poco driver class to patch things up.

If anyone's still having this problem, node["frame"] is returning a string since keys are not provided in that json data for some reason, (i.e. it looks something along the lines of this: "{{34, 67}, {337, 731}}"), and since it can't parse that into json data, it has to accept it as a string.

w = float(node["frame"]["width"])
h = float(node["frame"]["height"])
x = float(node["frame"]["x"])
y = float(node["frame"]["y"])

with this instead:

from re import search

if isinstance(node["frame"], str):
     frameData = search(r'{{(-?\d+\.?\d*), (-?\d+\.?\d*)}, {(\d+\.?\d*), (\d+\.?\d*)}}', node["frame"])
     x = float(frameData.group(1))
     y = float(frameData.group(2))
     w = float(frameData.group(3))
     h = float(frameData.group(4))
else:
     w = float(node["frame"]["width"])
     h = float(node["frame"]["height"])
     x = float(node["frame"]["x"])
     y = float(node["frame"]["y"])

Things should work fine after that.

In poco/drivers/ios/__init__.py, I modified like this :

    # w = float(node["frame"]["width"])
    # h = float(node["frame"]["height"])
    # x = float(node["frame"]["x"])
    # y = float(node["frame"]["y"])

    w = float(node["rect"]["width"])
    h = float(node["rect"]["height"])
    x = float(node["rect"]["x"])
    y = float(node["rect"]["y"])

And everything became alright. ( Still confusing...
