Ruby on rails 使用ruby 1.9.2、rails3.1.0，为什么在尝试生成脚手架时会出现错误。

基本上，当我试图生成一个脚手架时，我得到了这个错误

没有要加载的文件--openssl（LoadError）

。 错误来自于

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

不知道为什么会这样。以下是全部错误：

如果您在linux中使用，您可以尝试这些

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

---

您应该能够这样做：（请原谅我的路径中可能有错误，并且我不在linux机器上）

基本上，只需将您的特定ruby版本cd到gem的源目录，然后重新构建/安装它

---

您不需要重建ruby，这是一个常见的问题

好吧，我最后做的就是这个

• 已从rvm卸载所有版本的ruby
• 从rvm中删除所有宝石
• $rvm pkg安装openssl
• $rvm套件安装zlib
• $rvm安装1.9.2——使用openssl目录=$HOME/.rvm/usr——使用zlib目录=$rvm_路径/usr
• 在gemset中重新安装导轨

---

从那以后一切都很好

除非他重新编译Ruby，否则这很可能无法解决问题。这个问题是由ruby编译过程中丢失的libopenssl ruby库引起的。如果偶然发现此问题仍然存在，请阅读

rvm notes

的输出，它将告诉您要安装的确切软件包。我正在尝试这个。马上发现。。。。没用。

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