servo setup problem

[Bahauldien]

while assembling the car, when i connect the servos and open the server file on terminal & run the servo.py to set them up to 90 i get this message + error:
Now servos will rotate to 90°.
If they have already been at 90°, nothing will be observed.
Please keep the program running when installing the servos.
After that, you can press ctrl-C to end the program.

Please run the command to install smbus and try again.
sudo apt-get install python3-smbus

I have the same problem, and it’s not solved by reinstalling python3-smbus.

@HockeyD8 , @Shaynee-MO :
Just to confirm: is the I2C interface enabled on your Raspberry Pi? The FileNotFoundError message may occur if the I2C interface is not enabled.

How to enable I2C is discussed in "Step 2 Configuration" on page 37 of the PDF tutorial. Or,
here's one tutorial that walks through the process of enabling it via the command line utility.
