Ruby is garbled in Chinese characters in cmd and does not support OpenSSL. rubyopenssl

Chinese garbled code Solution
You cannot enter Chinese Characters in cmd.

Change the cmd code page to 936:

chcp 936

Ruby enforces UTF-8 for reading Chinese Characters

You can add a comment statement in the file # encoding: UTF-8, ruby will be loaded in UTF-8 format

Cmd output garbled characters

This cannot be solved. I see someone uses a third-party library to solve the output.

Require 'iconv' cov = iconv. new ('gbk', 'utf-8') puts cov. Iconv ("Beijing Olympics! ")

PS: In Ruby programs, it is best not to show Chinese characters, except for comments

Solve the problem that ruby does not support openssl.
When installing rails in RHEL 5.4 x86_64, the following error occurs: ruby does not support openssl.

Go to the $ RUBY_HOME/ext/openssl directory and run ruby exconf. rb. the following error occurs:

=== OpenSSL for Ruby configurator === === Checking for system dependent stuff... === checking for t_open() in -lnsl... no checking for socket() in -lsocket... no checking for assert.h... yes === Checking for required stuff... === checking for openssl/ssl.h... no === Checking for required stuff failed. === 
Makefile wasn't created. Fix the errors above.

The prompt is that ssl. h is not found and openssl-0.9.8k.tar.gz is downloaded from the http://www.openssl.org. Decompress the package and execute configure & make install. Return to $ RUBY_HOME/ext/openssl and re-execute.

ruby extconf.rb --with-openssl-include=/usr/local/ssl/include/ --with-openssl-lib=/usr/local/ssl/lib

Successful. However, a new error occurs when you execute make:

The system prompts you to re-compile openssl with the-fPIC parameter. So we re-compiled openssl.

.confile -fPIC
