gem install json -v 1.7.3 gives 'Please update your PATH to include build tools'

Question

When I run:

rails new blog

I get:

Installing json (1.7.3)
Gem::InstallError: The \'json\' native gem requires installed b         


        

Answer 1

sometimes when you run the ruby dk.rb init you got an error like this

for fixing this problem you have to change the encoding of the command prompt windows . to do this type chcp 1256 and you will receive this message : Active code page: 1256

now you can run that command without problem .

good luck .
