[ensembl-dev] LoadPlugins.pm problem

[Andy Yates]

Hi,

Can you check which Perl your apache instance is using? I only ask because I can only reproduce the error using versions of Perl lower than 5.14 (these examples use 3 perl versions I have installed on my local machine using perlbrew):

$ perlbrew use 5.14.2
$ perl -e 'for ("a", "b", "c") { my $filename = "$_->[1]/$filename" =~ s/\/+/\//gr; }'

$ perlbrew use 5.8.9
$ perl -e 'for ("a", "b", "c") { my $filename = "$_->[1]/$filename" =~ s/\/+/\//gr; }'
Bareword found where operator expected at -e line 1, near "s/\/+/\//gr"
syntax error at -e line 1, near "s/\/+/\//gr"
Execution of -e aborted due to compilation errors.

$ perlbrew use 5.10.0
$ perl -e 'for ("a", "b", "c") { my $filename = "$_->[1]/$filename" =~ s/\/+/\//gr; }'
Bareword found where operator expected at -e line 1, near "s/\/+/\//gr"
Can't modify string in substitution (s///) at -e line 1, near "s/\/+/\//gr"
syntax error at -e line 1, near "s/\/+/\//gr"
Execution of -e aborted due to compilation errors.

In fact the error suggests you're running a Perl which is either 5.10.x or 5.12.x. Can you confirm what perl -V returns back when you enter it on the command line?

Thanks,

Andy
