我已成功安装 Adafruit_Gpio 包，当我尝试运行 adafruit 提供的 bme 传感器示例文件时，出现以下错误：

  Traceback (most recent call last):
  File "/home/rpi3/Adafruit_Python_BME280/example.py", line 3, in <module>
    sensor = BME280(mode=BME280_OSAMPLE_8)
  File "/home/rpi3/Adafruit_Python_BME280/Adafruit_BME280.py", line 88, in __init__
    self._device = i2c.get_i2c_device(address, **kwargs)

  File "/usr/local/lib/python3.5/dist-packages/Adafruit_GPIO-1.0.3-py3.5.egg/Adafruit_GPIO/I2C.py", line 97, in __init__

    self.open(bus)
  File "/usr/local/lib/python3.5/dist-packages/Adafruit_PureIO/smbus.py", line 122, in open
    self._device = open('/dev/i2c-{0}'.format(bus), 'r+b', buffering=0)
FileNotFoundError: [Errno 2] No such file or directory: '/dev/i2c-1'

我在 xubuntu 上运行 rpi-3 我已经运行了 apt-get udpate 并重新启动了机器，但都没有用。

我在评论的帮助下找到了解决方案。特别是对于 xubuntu的步骤是：

sudo raspi-config

选择：

3 Interfacing Options

选择：

P4 I2C

和YES
