无法在ruby193上安装linecache19 gem

Question

I know this is one of the problem everybody is having these days and many of them have found ways to troubleshoot this problem. Unfortunately I have tried all the solutions but none of them seem to work on my system.

when I do

gem install linecache19

I get this error, as below

gem install linecache19
Temporarily enhancing PATH to include DevKit...

The system cannot find the path specified.

Use debugger-linecache , it's just an updated working fork of linecache19. You won't have installation issues like the one you are having because it's not built as a C extension anymore, it's 100% ruby.

gem install debugger-linecache

Hope it helps.
