Error Instaling Sass

[EddAvila]

When I try to install sass, I get this error ->

ERROR: Error installing sass:
invalid gem: package is corrupt, exception while verifying: undefined method 'size' for nil:NilClass (NoMethodError) in C:/Ruby22-x64/lib/ruby/gems/2.2.0/cache/sass-3.4.19.gem

I'm trying to install sass with the ruby command prompt in windows

Hi, I think you're downloaded gem file is corrupted somehow. Please remove that file and try again.

[EddAvila]

Yes, I try that, for now I have an earlier version installed

@EddAvila I'm glad you have a work around. Unfortunately, none of the Sass developers have a Windows machine so we can't reproduce this.

➜  rbenv shell 2.2.3
➜  gem install sass
Fetching: sass-3.4.19.gem (100%)
Successfully installed sass-3.4.19
1 gem installed

All the similar issues I see on google indicate that this is due to a corrupted ruby install or gem.

For Ubuntu users, I had a similar issue but deleting the already downloaded [corrupt] gem [~/.rbenv/versions/2.4.1/lib/ruby/gems/2.4.0/cache/sass-3.5.1.gem] and reinstalling it fixed the problem.

rm ~/.rbenv/versions/2.4.1/lib/ruby/gems/2.4.0/cache/sass-3.5.1.gem
gem install sass -v '3.5.1'
