Question

基本上，当我尝试生成脚手架时，我收到此错误 no such file to load -- openssl (LoadError)。错误来自

.rvm/gems/ruby-1.9.2-p290@rails310/gems/activesupport-3.1.0/lib/active_support/dependencies.rb:240:in `block in require'

不确定为什么会这样。这是完整的错误：

Answer 1

好的，我最终做的就是这个。

从rvm
从rvm
$ rvm pkg install openssl
$ rvm pkg install zlib
$ rvm install 1.9.2 --with-openssl-dir = $ HOME / .rvm / usr --with-zlib-dir = $ rvm_path / usr
重新安装gemset中的rails

之后一切正常。

Answer 2

你应该可以做这样的事情:(原谅我的路径中可能有错误而我不在我的linux盒子上这一事实）

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

基本上，只需cd到您的特定ruby版本的gem的源目录，然后重建/安装它。

你不需要重建ruby，这是一个常见的问题。

Answer 3

如果您在Linux中可以尝试这些

apt-get install openssl
apt-get install libopenssl-ruby

使用ruby 1.9.2，rails3.1.0，当我尝试生成脚手架时，为什么会出现错误。
