问题
Hi I am using ActivePerl 5.10.1 on Win XP.
I can't find Lex package from the PPM list.
Can I install other package to enable Parse::Lex?
回答1:
I do believe ParseLex is in the base set of packages in PPM. Try:
> ppm install ParseLex
from the command line? You'll need to set the http_proxy environment variable if behind a proxy, you can do it for that session only by issuing this before the command above:
> set http_proxy=http://host:port/
e.g.
> set http_proxy=http://10.100.9.10:8080/
If using the GUI... I believe the set of packages displayed by default is the installed set so you'd be searching that for Lex. Click View -> All Packages if this is the case.
