Install all used modules at once作者：gugod 發佈於：
Ever since perlbrew was made useful, switching among different versions of perl makes it painful to re-install the required modules over and over. That's why I wrote this module-used program to rescue me.
The usage of
module-used is heavily inspired by tokuhirum++'s cpan-outdated program:
cd /to/my/awesome-project module-used
That gives you a list of module names which are found to be used in some source files under current directory. It can then be piped to
xargs cpan -i to perform bulk module installation:
module-used | xargs cpan -i module-used | xargs cpanm
cpanm --installdeps is doing basically the same thing here, this program is also helpful for module authors to get a list of names for their
Build.PL, which might not be there in the first place if the current project is not planed to be uploaded to CPAN.
module-used program itself uses
List::MoreUtils , install them first, and the the program should be ready to run.
