python ModuleNotFoundError 问题

import sys

print(sys.path)
sys.path.insert(0, "/usr/lib/python3/dist-packages")
sys.path.insert(1, "/usr/local/lib/python3.7/dist-packages")
import usb
print(usb.__file__)
if __name__ == '__main__':
	pass

pip3 install usb
pip3 install pyusb
pip3 install libusb

和

sudo pip3 install usb
sudo pip3 install pyusb
sudo pip3 install libusb

安装的不是同一个地方
