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:

Answer

If you answer a question - or have a question you asked answered by someone - please remember to edit the page and set the status to answered. The status is in a drop-down list 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

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?
