Ruby on Rails: rb_class_superclass不在msvcrt-ruby191.dll中(ruby-prof error?)

Question

所以，长话短说，我已经格式化并重新安装了我的操作系统，因此我的所有开发工具。git环境已排序。DevKit很好。Sphinx/mysql很好。捆绑包安装完美。在我访问rake db:create and build my database之前，一切都很轻松。

环境: OS: Win7 64位Ruby192 gem -v 1.8.24 rails 3.1.3

现在的问题是，当我搜索任何东西时，我会得到一个弹出窗口

ruby.exe - Entry Point Not Found

The procedure entry point rb_class_superclass could not be located in the dynamic link library msvcrt-ruby191.dll

我尝试过干净利落地安装ruby，清除gem，然后重新安装。不知道下一步该怎么做。

跟踪输出：

我也看到过类似的问题，但是针对dll中的不同行，并且与sqlite3相关。不过，我根本没有使用sqlite3。我在mysql上使用mysql2连接器。

有什么帮助吗？

Answer 1

我想我想通了。

在我替换的gemfile中：

gem "ruby-prof"

通过以下方式：

gem "ruby-prof", "0.10.8"

突然，我开始讨论下一个问题，那就是详细说明我的rake版本。我认为这两个问题都与gem和我的rubygems verson之间的不兼容有关(我猜是？？)。这是我的笔记本电脑环境、台式机环境和生产服务器之间唯一的区别。

无论哪种方式。排序好了！
