Rector: Class (...) was not found (...) autoloading is probably not configured properly

[cve]

Hi,

I have tried all possible methods of install rector and only global composer rector-prefixed work, when I run this command:

rector process app src --level symfony30

the output is:

````

so, I removed cache and this time is:

My project is working Symfony 2.8 app and I have to upgrade it to 3.4... could you help?

Hi, exclude all the files that are temporary. I see app/cache/dev

See the docs: https://github.com/rectorphp/rector#exclude-paths-and-rectors

---

Also, prefered installation is composer dependency or Docker. global composer installation will result in false positives as the paths and behavior is very differnt from composer dependency.

As for prefixed Rector, it's WIP and it doesn't work yet, see: https://github.com/rectorphp/rector/issues?q=is%3Aissue+is%3Aopen+sort%3Aupdated-desc+label%3Awaits-on-prefixed

With docker it's not working too.

my rector.yml file:

yaml parameters: autoload_paths: - 'vendor/autoload.php' exclude_paths: - 'app/cache/dev' - '*/src/*/Tests/*'

When I run docker:

````
docker run -v $(pwd):/project rector/rector:latest process /project/src --level symfony30 --config /project/rector.yaml
Rector No version set (parsed as 1.0.0)@

@cve did you ever get it working? I have exactly the same issue with the docker image with a symfony project and a very similar config to yours

[cve]

@REBELinBLUE I didn't

[TomasVotruba]

Composer global install is not recomended, as the Rector code is not designed to run well in it

[REBELinBLUE]

I wasn’t installing globally and I still had this issue

[TomasVotruba]

In that case it's different issue than first reported here.

Please create a new one with steps to reproduce.

[EuphorialIRE]

@REBELinBLUE Any joy with this? Or was it just closed with no solution?

[REBELinBLUE]

I didn't have any joy I'm afraid

[TomasVotruba]

All classes have to be autoloadable either with composer, or with Rector (see README).

If you're able to reproduce in standalone repository, I can help you.

[FireLizard]

Any Update on this?

I'm still getting a similiar error:
