Arduino Upload No Such File or Directory

Are you lot trying to run an Arduino sketch, but keep coming across a "No such file or directory" fault? This is a pretty mutual error! Keep watching to learn more than about 2 easy fixes for this error.

No such file error!

Mistake letters can be such a pain, only they're supposed to tell us something almost the mistake we made. Let'southward have a look at the one below. If y'all look at the lesser portion of the Arduino IDE where the error message shows upward, there's this handy little button that says "copy mistake messages".

If y'all click on it, it copies the error bulletin inside the piddling window to the clipboard on the estimator.

What you can do now is paste it into Google, for example, and do a search which can help you detect out more than about the error. Or you could paste it into a forum and say, "Hey, I've got this error message, please help me."

For this situation, still, nosotros've copied information technology and we're going to paste it into a text editor and then we tin can take a closer await at what the error message is actually saying.

Decoding the no such file mistake

The first sentence but says which Arduino version is in use, which operating organization is running, and which board is selected.

The 2d judgement actually starts getting into the error a little bit. The outset thing information technology gives us is the name of the program. And so, in this case, the name of the plan was "Knob".

If you look at the Arduino IDE, the the numbers on the left are called line numbers of the program and they're a reference to assistance us detect where unlike lines of code are. The "10" later on "Knob" is the line number (in the Arduino IDE) that the error was detected on.

The "xix" is a reference to how long that line of code is, so how many spaces or characters long is it.

Then it tells united states of america the actual error. Information technology says "servo.h: No such file or directory". Why are nosotros getting this error?

The error of our ways

Well, let'due south take a await at line 10 and see what it says. It says "#include <servo.h>"

When we verify this code, what this line does is tell the Arduino IDE compiler "Hey, for this program to piece of work, you demand to go get this file servo.h".

Allow's say you had a label making machine and you were trying to run the label maker and impress some labels. To go far work, y'all accept to put in a roll of labels. If you lot don't have that scroll of labels, then your label maker isn't gonna piece of work. Then our program'due south like the label maker and the file (servo) is the roll of labels.

Then the mistake message is like "Hey, programmer, yous said I needed this other file… merely I looked for it and it's non in that location. What gives? Let's get to the bottom of this mistake message and go over two different scenarios.

Scenario i – fat fingers

This sketch is i that yous've written. You're really the one who wrote the "#include" line. The start thing you lot should check is your spelling and capitalization. Possibly you lot spelled the name of the library incorrectly, or in this case, maybe yous didn't capitalize the right letters.

So "servo.h" should really exist a upper-case letter "South", or written out, "Servo.h". Now in this example, you'll notice that the word servo changes colour when correctly capitalized, and that's considering the library proper noun "Servo" is recognized as a "key word" in the Arduino IDE. Keep in mind that might not be the case for all the libraries that you're using.

Therefore you tin't utilize whether or not information technology color inverse as an absolute indicator, but it can exist helpful. It is amazing how long y'all tin can stare at a line of lawmaking and miss something like a spelling or a capitalization error.

Scenario 2 – missing files

In this scenario you've either downloaded or copied and pasted some code from the internet and yous're trying to run it for the first time. At present you first getting this error message. Permit'south just presume that the original author of the programme spelled the name of the library correctly.

We'll go ahead and skip the troubleshooting associated with scenario 1. The side by side step would be to verify that we really have the file this program is calling for. We must also ensure the file is in the right place.

An easy style to check to meet if you have that file is to exist in the Arduino IDE and go to Sketch > Include Library, and and then look for the name of that library.

Whatever library the #include statement was calling for, you desire to look through this big long list for that library. If you lot don't see its exact name in this list, this means you lot do not accept that library installed accordingly (they're all in alphabetical order which helps). If y'all don't meet it here, you'll have to add the library.

The easiest way to add a library is to go to Sketch > Include Library > Manage Libraries. It will open a dialogue box and you can search for a library. There's so many libraries, you're definitely going to want to filter.

Make sure y'all type the verbal word that matches the #include line. One time you observe the missing library click install. Information technology will let yous know that information technology's installing the library and updating the listing of libraries.

Next nosotros can double-check it has successfully installed. Go to Sketch > Include Library and the installed library should now announced on the driblet down list. At present, when it complies, y'all should no longer go the error.

Other library locations

Not all libraries are in this convenient pop-up window when yous go to manage libraries. There'south tons of unlike ways to find Arduino libraries on the web. Ofttimes, if you're downloading or copying a program from the internet, but get to the page where y'all got that programme and see what library they're referencing. Maybe they have a link to GitHub, for example, which is a place where people go on a lot of code libraries.

Usually the library is included in a .zip file package. In one case you've downloaded the .zilch file, you can go to the Arduino IDE and go to Sketch > Include Library > Add together .ZIP library… You lot but have to navigate to where the file was downloaded. It will tell yous "Library added to your libraries" just above the dark area where the original fault had appeared.

Now when nosotros go to Sketch > Include Library, the new library volition announced in the drop-downward list. Viola! You now know 2 ways to add together a new library.

Review

And so we've discussed two possible scenarios that could cause the "No such file or directory" fault to appear afterwards you compile your sketch.

Start, if you wrote the sketch, simply double-check your spelling and capitalization.

Second, if you take copied code from someone else, make sure you accept the correct libraries installed.

We promise you take a nifty one and we'll run into you lot next time! Goodbye!
