nxt-py无后端错误

Question

我正在尝试使用pyusb运行nxt py库的一个示例脚本。每当我尝试运行这些示例时，我都会得到以下错误：

USB module unavailable, not searching there
Bluetooth module unavailable, not searching there
Traceback (most recent call last):
File "C:\Documents and Settings\*\Desktop\nxt-python-2.2.1\examples\mary.py", line
15, in <module>
b = nxt.locator.find_one_brick()
File "C:\Python27\lib\site-packages\nxt\locator.py", line 112, in find_one_brick
for s in find_bricks(host, name, silent, method):
File "C:\Python27\lib\site-packages\nxt\locator.py", line 80, in find_bricks
raise NoBackendError("No selected backends are available! Did you install the comm
modules?")
NoBackendError: No selected backends are available! Did you install the comm modules?

我不知道如何解决这个问题，我想知道除了切换到蓝牙之外，还有没有其他方法？

Answer 1

USB和蓝牙不可用。您需要安装python模块才能运行示例。这是安装指南，choose your operating system。

对我来说(mac os x)只适用于fantomusb。此外，我还需要设置砖块定位器的属性来找到它。

b = nxt.locator.find_one_brick(name="NXT", strict=True, method=nxt.locator.Method(bluetooth=False, fantomusb=True, fantombt=False, usb=False))
