BQ27441 error compiling to arduino

I have bought a Sparkfun battery babysitter and want to use to measure current in the lithium battery.
I copy the sample code showed in the example code provided, but when I verified it, it shows

fatal error: SparkFunBQ27441.h: No such file or directory

#include <SparkFunBQ27441.h>


compilation terminated.

exit status 1
Error compiling for board Arduino/Genuino Uno.

I am new to this device and its coding,I don’t know what is the problem for it, I did not change anything form the sample code. :disappointed_relieved: I want to know where is the problem or is there any thing I have to add?

Also, if there are any site can teach how to use this babysitter I will like to learn from it,

Thank for anyone answering.

When you see a "No such file or directory" error it almost always means you need to install the library that contains the missing file.

Often the code you're compiling will come with documentation (either a comment or separate document) that tells you where to get the library dependencies.

In other cases the author of the code will not have been so kind and you'll need to go on a hunt for the missing library.

A good place to start is the Arduino IDE's Library Manager:

  • Sketch > Include Library > Manage Libraries...
  • In the "Filter your search..." box, type some keywords you have gleaned from the missing file name.
  • Scroll through the results for the right library. Click on it.
  • Click "Install".
  • Wait for installation to finish.
  • Click "Close".
  • Try compiling your code again.

If you have no luck in Library Manager then load up your favorite search engine and do a search for the missing filename. You will often get multiple results. If you have a lot of results you might add "arduino" as an additional search keyword. I will usually prefer results on since that is where most Arduino libraries are hosted and downloading from there is fast and easy. In some cases there will be multiple libraries that contain the given filename and you'll need to do some evaluation to determine which seems the most appropriate, then try it out. After downloading the library you found you'll need to install it. This requires a different process than the Library Manager installation. You will find instructions here:
