我从 Rails 3.0.11 升级到 3.1.3。当我启动服务器时，它给出了错误：

也许 ffi gem 没有正确安装？

gem uninstall ffi

假设您使用的是 Ubuntu：

sudo apt-get install libffi libffi-dev
gem install ffi -v 1.0.11

因为我已经安装了“ffi”。我必须找到另一个解决方案，试试下面（这对我有帮助）：

找到文件“libffi.so.5”，如果不存在，请检查“libffi.so”。（在我的情况下是 6，即 libffi.so.6）。

现在取消链接与“/usr/lib64/libffi.so.6”关联的文件。（在我的例子中，它指向“libffi.so.6.0.1”）

现在为“libffi.so.5”创建一个新的符号链接，这样“/usr/lib64/libffi.so.5”应该指向新的符号链接“libffi.so.6.0.1”。

即，最终设置应如下所示：-“/usr/lib64/libffi.so.5 -> libffi.so.6.0.1”

希望这会有所帮助。（我使用基于 Amazon Linux AMI 的实例。）

这对我有用。

ln -s /usr/lib64/libffi.so.6 /usr/lib64/libffi.so.5
