The doctrine class loader should no longer be used, as composer completely replaces it: are your examples coming from the docs? If so, then we'll likely need to upgrade or deprecate that section.

[Th3Ov3r]

Yes, the examples take them from doctrine couchdb documentation.
What is the correct way to download and load the libs, help me please.

[mikeSimonson]

On the command line you can composer require doctrine/couchdb-odm and then you just need to require_once the vendor/autoload.php file.

Can you point us where you found the outdated documentation that show the use of the doctrine classLoader ?

[Th3Ov3r]

Here docs
http://docs.doctrine-project.org/projects/doctrine-couchdb/reference/configuration.html#class-loading

Now, I'm having this problem
C:\xampp\htdocs\couchdb-odm-master>composer require "doctrine/couchdb-odm"
[InvalidArgumentException]
Could not find package doctrine/couchdb-odm.

Did you mean one of these?

[mikeSimonson]

Thanks for the docs link.

The error that you are seeing from composer is weird.
It looks like there is an invisible character because the error mention the right package.
Also you shouldn't require doctrine/couchdb-odm in what looks like a git clone from doctrine/couchdb-odm but in your project where you want to use it.

[Th3Ov3r]

Yes, very strange. Try other libs, such as, for example,

composer require "doctrine/mongodb-odm"

If it worked well.

[Th3Ov3r]

try another pc. I keep throwing error. But this time the
exception is different. What could be happening?
I think he asks me to specify the version, what version should I specify?

C:\xampp\htdocs\couchdb>composer require doctrine/couchdb-odm

[InvalidArgumentException]
Could not find a version of package doctrine/couchdb-odm matching your mini

[mikeSimonson]

Sorry but I have no idea what's going on, but it's not a couchdb-odm bug.
