Answer 1

At our last Usergroup we figured out the reason. We found out that the problem arises when zipping the extension locally on Mac OSX command line. All files looses its access rights and properties that causes the effect that the ext_emconf.php can't be found during the install process. If you download the zip from an installed live system everything is fine.

We doesn't work out the correct command on Mac OSX command line. It would be awesome if someone can work out the right command for zipping on command line.

Answer 2

Dependencies must have both upper and lower boundaries defined.

Technically your line 'extbase' => '7.6', has no value at all.

• Do you want to restrict from 7.6 upwards?
• Or restrict to a maximum of 7.6?

What's 7.6 after all?

• 7.6.9970970?
• 7.6.0?

You see, there is no valuable information that can be pulled from this.

This is why you need to provide specific boundaries like this for example:

'extbase' => '7.6.15-7.6.99'

PSA:

Be extremely careful with loose upper bounds. We see people going 7.6.0-9.99.99. Unless you own some magic crystal ball that can foretell the future, it's better to raise the dependency constraints once you actually tested them.

Regarding the issue on a Mac

The problem is not (only) the hidden MAC_OS folders. The issue is, that OS X does not put the content of chosen Typo3-Extension-Folder into the archive but the folder as single root element itself. Then Typo3 cannot find the files. You must go into the extension folder and run then the zip command.

Example: We are in my working directory which is named output. The extension folder is called jfmulticontent_3.0.0-dev_201810051125. Then you would have to run:

BOB-NB2:output bob$ cd jfmulticontent_3.0.0-dev_201810051125/
BOB-NB2:jfmulticontent_3.0.0-dev_201810051125 bob$ zip -r -X ../jfmulticontent_3.0.0-dev_201810051125.zip *
