LoadError: libffi.so.8: 无法打开共享对象文件: 没有这样的文件或目录正在运行 Rails

Question

我在创建新的 Rails 项目时遇到问题。当我运行时rails new project_name，它失败并出现rails webpacker:install以下错误：

我使用 ASDF 进行 ruby​​ 版本管理。

我尝试了许多解决方案，例如卸载和安装 gem、运行gem pristine以及 SO 和此处提供的一些其他方法。

Answer 1

感谢@Knud Larsen的评论，这对我在 Ubuntu 20.04 上有用：

wget http://fr.archive.ubuntu.com/ubuntu/pool/main/libf/libffi/libffi8_3.4.2-1ubuntu5_amd64.deb
sudo dpkg -i ./libffi8_3.4.2-1ubuntu5_amd64.deb

Answer 2

当我从事 Rails 项目时，我意识到系统版本和项目版本之间存在差异，因此我的解决方案是通过运行以下命令来匹配两者：

gem uninstall ffi 
gem install ffi -v 1.15.0 -- --disable-system-libffi
