Google-cloud-php: Class 'Google\Cloud\Vision\VisionClient' not found

[scottkriesberg]

I am trying to use the google vision api example (the first one) on this page. https://cloud.google.com/vision/docs/detecting-text#vision-text-detection-php
But I keep getting this error: Fatal error: Class 'Google\Cloud\Vision\VisionClient' not found. Has this happened to anyone else and if so how did the fix it?

Hey @scottkriesberg ,

Have you included the composer autoload file?

[scottkriesberg]

No at the moment the code is exactly like that of the example with my project id and image path filled in. I added this line require __DIR__ . 'vendor/autoload.php'; but it could not find the file. I installed composer, but I think I may be doing this wrong.

[dwsupplee]

It sounds like you may need to run composer require google/cloud-vision. That should pull down the package and generate the autoload file for you.

[scottkriesberg]

Should I still include the require __DIR__ . 'vendor/autoload.php'; line before the use Google\Cloud\Vision\VisionClient; line?

[dwsupplee]

Yep! It should look something like this example.

[scottkriesberg]

That is what I tried before and downloaded the files using composer. It even said autoload files were generated, but when I run it it cannot find the autoload file and tells me to (include_path='.:'). How do I get it to find the right autoload file?

Take a look at this stackoverflow question and let me know if it helps.

[scottkriesberg]

Thank you that seemed to work, but now it is saying "Request had invalid authentication credentials" so I am working on that.

[dwsupplee]

We have a guide that should help with that :).
