Cannot declare class ProcessWire\ProcessModuleInstall, because the name is already in use

[MarkE]

Just tried to install a new module (RockCalculator from @bernhard) and got this message. I don't think it's anything to do with his module, so posting here as a general query. Any ideas what might be causing it? (BTW it installed OK by downloading the files manually)

I've also had those errors lately... Not sure what is the reason because it have been bigger projects with lots of modules under heavy development and also on latest DEV which had some issues lately. Do you have any other of my modules installed? RockFrontend? RockMigrations?

On 3.0.203. No other modules of yours installed, but planning RockFrontend and maybe RockMigrations

Hi @bernhard. Just tried a different module (AppAPI) which is OK. The problem appears to be with your modules. I tried RockMigrations too - on v3.0.200 - both RockMigrations and RockCalculator give this error: ProcessWire: ProcessModule: No page specified

Ok great thx @MarkE can you track it down further or do you have a reproducible steps of actions that I can take to debug it myself?

I’ll look into it when I get a moment. Manual install seems ok.

Hi @bernhard. Had a quick look at this. It's a bit of a puzzle to me. The problem occurs when clicking the "Get Module Info" button on the new modules tab.

I tried on 3.0.200 and 3.0.203

In 3.0.203, all I get is a compile error - see the title of this thread - so it's a bit difficult to diagnose as there is no obvious cause. This happens with RockCalculator and RockMigrations, but NOT RockFrontend. (Although I have not yet proceeded to install RockFrontend I have no reason to believe it won't install).

In 3.0.200 I get the "ProcessWire: ProcessModule: No page specified" error. This is generated by ProcessPageEditImageSelect::init() (line 292 or 294). I have no idea why PW is even in that class. See the trace below

Again, this happens with RockCalculator and RockMigrations, but not RockFrontend.

I inserted a debug_backtrace - see here (unfortunately lost indents on paste from Tracy), which explains more:
