python - Can we use pip downloaded files after an install error? -

this newbee question. forgot add sudo before pip install, , got permission denied message after whole while. there method can make use of downloaded files when invoke pip command sudo subsequently, can save bandwidth. ditto gem install. thanks.

no, can't you're asking, @ least not , securely.

to want involve changing user ownership of parts of system, bad lot of reasons. or, you'd have change group or add group, bad same reasons first. in both cases, odds of damaging system beyond repair goes way up.

we have sudo reason; it's keep running system administrator time , shooting ourselves in foot. invoking command using sudo gives chance pause , think whether want that. adds thin layer of sanity-checking code looks see if safe command issue, can tweak allow/disallow particular actions.

if choose go last route, how off-topic stack overflow , should asked on http://superuser.com instead.
