Question

I've had lots of problems trying to install YetAnotherDBCacheContrib (and the YetAnotherXpTrackerPlugin). With a virgin installation of TWiki 4.1.2 to /var/www/twikikae (a test location), I have clicked on 'Install' from the configure/plugins page. The output I get is:

Fetching http://twiki.org/p/pub/Plugins/YetAnotherDBCacheContrib/YetAnotherDBCacheContrib.tgz...
Warning: I can't install http://twiki.org/p/pub/Plugins/YetAnotherDBCacheContrib/YetAnotherDBCacheContrib.tgz
because I don't recognise the download as a gzip file.
Warning: Extension may not have been packaged correctly. Trying for a .zip file instead.

Error: Failed to move file 'lib/TWiki/Contrib/DBCacheContrib/' to /var/www/twikikae/lib/TWiki/Contrib/DBCacheContrib: Is a directory

Software error:

Installation terminated at /var/www/twikikae/lib/TWiki/Configure/UIs/EXTEND.pm line 149.

The directory permissions and contents are as follows: I can see no reason why the file move failed, and 'is a directory' implies that the destination already exists, but as can be seen below, it doesn't:

Grateful for any guidance.

Answer

If you answer a question - or someone answered one of your questions - please remember to edit the page and set the status to answered. The status selector is below the edit box.

The installation failure is due to an old installer script. Just ignore the installer script, and download the zips and unpack them.

Last time I loooked, all the functionality of YetAnotherDBCacheContrib had been back-ported to DBCacheContrib. I do know that YetAnotherDBCacheContrib is not actively supported, so good luck getting answers on that one.

I can't comment on YetAnotherXpTrackerPlugin.

Thanks, but that hasn't helped very much. I downloaded and ran DBCacheContrib_installer. Here's proof, when I try to run it again:

# perl DBCacheContrib_installer

### DBCacheContrib Installer ###

This installer must be run from the root directory of your TWiki
installation.
    * The script will not do anything without asking you for
      confirmation first (unless you used -a).
    * You can abort the script at any point and re-run it later
    * If you answer 'no' to any questions you can always re-run
      the script again later

DBCacheContrib version $Rev: 13562 (28 Apr 2007) $ is already installed. Are you sure you want to re-install this module? [y/n] n

So now I downloaded and ran YetAnotherXpTrackerPlugin_installer:

# perl YetAnotherXpTrackerPlugin_installer

*** YetAnotherXpTrackerPlugin depends on perl package TWiki::Plugins::DBCacheContrib >=0
which is described as "Required. Download and install from [[TWiki:Plugins/YetAnotherDBCacheContrib][plugin library]]."
But when I tried to find it I got this error:

Can't locate TWiki/Plugins/DBCacheContrib.pm

Would you like me to try to download and install the latest version of DBCacheContrib from twiki.org? [y/n] n

Fetching the archive for TWiki::Plugins::YetAnotherXpTrackerPlugin.

So: first it says it can't find DBCacheContrib.pm, which we know is installed. Then it "can't create a filehandle" for the tgz file, which has been downloaded and exists.

Why is this so damn hard? Am I doing something stupid?
