使用设备检测器库时出现UnicodeDecodeError

Question

我正试图以这种方式使用dvice Deactor解析器

from device_detector import DeviceDetector

ua = 'Mozilla/5.0 (Linux; Android 6.0; 4Good Light A103 Build/MRA58K) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.83 Mobile Safari/537.36'
device = DeviceDetector(ua).parse()

我收到以下错误信息：

Traceback (most recent call last):
  File "C:/Users/mozer/PycharmProjects/test/new.py", line 83, in <module>
    device = DeviceDetector(ua).parse()

    return codecs.charmap_decode(input,self.errors,decoding_table)[0]
UnicodeDecodeError: 'charmap' codec can't decode byte 0x8a in position 10444: character maps to <undefined>

我主要在尝试读取文件时看到这个问题。 有人知道吗

谢谢

尝试将encoding="utf-8"添加到打开正则表达式的行中 i、 e.将其改为：

with open('{}/{}'.format(ROOT, yfile), 'r', encoding="utf-8") as yf:

对我来说，这是设备检测器文件夹中“yaml_loader.py”的第34行
