Rails：没有要加载的此类文件—生成模型时的openssl

Question

I am using Rails 3.1.1 and ruby 1.9.2-p290 .

When I try to generate model with command:

rails generate model Car name:string

I got the error message:

.rvm/gems/ruby-1.9.2-p290/gems/activesupport-3.1.1/lib/active_support/dependencies.rb:240:in `require': no such file to load -- openssl (LoadError)

I tried to get rid of it by using method

and also tried :

cd to ~.rvm/src/ruby-1.9.2-p290/ext/openssl
ruby extconf.rb
make
make install

But, neither of them help. Anyone has any ideas about this error?

Answer 1

Is seems you are missing libraries for openssl. Try installing these packages.

sudo apt-get install libssl-dev
sudo apt-get install libopenssl-ruby1.9.1

if you are using rvm then and getting same error then try following

rvm pkg install openssl (old code for rvm - rvm package install openssl)
rvm pkg install iconv (old code for rvm - rvm package install iconv)
rvm remove 1.9.2
rvm install 1.9.2 -C --with-openssl-dir=$HOME/.rvm/usr,--with-iconv-dir=$HOME/.rvm/usr
