Question

我写了一个可以从Pycharm完美运行的脚本。但是，如果我从终端运行此代码，则说找不到模块。

代码如下：

from rplidar import RPLidar, RPLidarException

lidar = RPLidar('/dev/ttyUSB0')

info = lidar.get_info()
print(info)

health = lidar.get_health()
print(health)

try:
    for i, scan in enumerate(lidar.iter_scans()):
        scan_data = []
        for d in scan:          #d[0] : Quality of the measurement
            '''if 0< d[1] <15:     #d[1] : Angle of the measurement
                print(d[2]/10)  #d[2] : Distance of the measurement '''



        if False:
            lidar.stop()
            lidar.stop_motor()
            lidar.disconnect()
            break
except KeyboardInterrupt as err:
    print('key board interupt')
    lidar.stop()
    lidar.stop_motor()
    lidar.disconnect()

except RPLidarException as err:
    print(err)
    lidar.stop()
    lidar.stop_motor()
    lidar.disconnect()
except AttributeError:
    print('hi attribute error')

当我以下面的方式运行此程序时：

python -m main.py

我收到此错误：

Traceback (most recent call last):
  File "/usr/lib/python2.7/runpy.py", line 174, in _run_module_as_main
    "__main__", fname, loader, pkg_name)
  File "/usr/lib/python2.7/runpy.py", line 72, in _run_code
    exec code in run_globals
  File "/home/shahin/PycharmProjects/RpLidar/main.py", line 1, in <module>
    from rplidar import RPLidar, RPLidarException
ImportError: No module named rplidar

如果您告诉我如何克服这个问题，我将感到非常高兴。

同时，当我在pycharm中运行此代码时，我想从中捕获KeyboardInterrupt。但是它不起作用。即使我也做Contro + c。

有人可以告诉我谁也可以在pycharm中执行KeyboardInterrupt。

如果显示的是python 3.7，请转到终端类型python3，然后键入python3 -m main.py或python3 main.py

从终端运行python脚本时未加载模块
