尝试将 MPU6050 连接到在 Beaglebone-IO 下运行 Debian、Node.js 和 Johnny-5 的 Beaglebone Black。
使用 Johnny-5 示例初始化 MPU6050：
var imu = new five.IMU({
controller: "MPU6050"
});
每次发生错误时：
TypeError: Object #<BeagleBone> has no method 'i2cConfig'

我想这与 i2c 配置有关，因为我无法使用 npm install i2c 安装 i2c，它总是输出：
make: *** [Release/obj.target/i2c/src/i2c.o] Error 1
make: Leaving directory `/root/node_modules/i2c/build'
