Question

我将 Rails 升级到 7.0.1。当我执行 rails g controller Pages home 时，出现错误：

知道如何解决这个问题吗？

Answer 1

您可以使用它附带的内部libffi编译ffigem。确保版本匹配：

gem install ffi --version '1.15.5' -- --disable-system-libffi

我不知道为什么 ffi 使用系统 libffi 可以很好地编译，但随后拒绝使用它运行。

Answer 2

您很可能需要安装 libffi。在 CentOS/RHEL/Fedora 系统上，您需要执行：

sudo dnf -y install libffi

Answer 3

当我从事 Rails 项目时，我意识到系统和项目一之间的版本存在差异，因此我的解决方案与两者相匹配：

1. gem 卸载 ffi
2. gem install ffi -v 1.15.0 -- --disable-system-libffi

   Ubuntu 版本 (20.04)

Answer 4

将我的 ubuntu 从 20.04 更新到 20.10 并安装 Ruby version 3.0.2 和 Ruby On Rails version 7.0.0 。 那解决了错误。
