ROUGE-1.5.5.pl - XML::Parser dependency error

[cgebe]

ROUGE-1.5.5.pl has a XML::Parser dependency, without this module installed, the following error is printed:

Probably good to mention in the README

Solution:

$ apt-get install -y cpanminus
$ cpanm --force XML::Parser

[coree]

For me the command sudo apt-get install libxml-parser-perl worked. However, the parser was not installed in my case and cpanminus didn't worked.

is there a mac equivalent?

[pltrdy]

@sshleifer I'm not a Mac user but I would guess:

• install xml stuff brew install libxml2
• get perl/cpanminus http://www.cpan.org/modules/INSTALL.html
• cpanm --force XML::Parser

[markusdr]

On systems with yum, this works well:

sudo yum install -y "perl(XML::LibXML)"

See also: https://grantm.github.io/perl-libxml-by-example/installation.html

And, for good measure, to avoid another common error:

sudo yum install -y "perl(DB_File)"

Is there a Windows equivalent?

[pltrdy]

@wentinghome I'm not using Windows.

However, it seems like you may install perl with either strawberry or activestate (see https://grantm.github.io/perl-libxml-by-example/installation.html#installing-on-windows) so you can:

# strawberry
cpan XML::LibXML

# active state
ppm install XML::LibXML

how to resolve this problem without using sudo in for Ubuntu? I am having a hard time. If someone can help that will be great!
