推荐答案

gem install ffi 失败，原因是 gem 试图构建 libffi 的捆绑副本，由于假设/usr/bin/env 存在而无法工作和太旧的 libffi 副本.

The gem install ffi fails due to the gem trying to build a bundled copy of libffi, which does not work due to assumptions that /usr/bin/env exists and too old libffi copy.

但是，您可以针对系统 libffi 构建 ffi gem - 安装软件包:

However, you can build the ffi gem against the system libffi - install the packages:

apt install clang make ruby-dev libffi-dev

在那之后 ffi gem 应该构建:

After that the ffi gem should build:

gem install ffi
