Ruby on Rails：没有这样的文件可以加载 - 在RedHat Linux Enterprise上打开openssl

Question

I am trying to do 'rake db:migrate' and getting the error message 'no such file to load -- openssl'. Both 'openssl' and 'openssl-devel' packages are installed. Others on Debian or Ubuntu seem to be able to get rid of this by installing 'libopenssl-ruby', which is not available for RedHat. Has anybody run into this and have a solution for it?

Answer 1

I had this problem on Ubuntu, after upgrading to 8.10. The solution for Ubuntu was

sudo apt-get install libopenssl-ruby

Answer 2

it seems you need to make the ruby header file

go into the openssl directory and:

ruby extconf.rb
cd ../..
make
make install

See here

Answer 3

If you are using RVM to manage your rubies follow the directions here:

http://rvm.io/packages/openssl/

Answer 4

I had the same issue. I tried going into the openssl folder and running make etc but it couldnt find the libraries lcrypto. I solved the issue by running ruby 1.9.3-p327.

Hope this helps!

Answer 5

There is probably a gem you are missing. Can you provide the stack trace and the line of code where it originates?

Re-run rake with --trace to get the stack trace printed.

EDIT: Also what version of Ruby are you running? openssl.rb is in my 1.8.6 install
