我在运行时遇到了一些问题bundle install。我收到类似的消息Errno::EACCES: Permission denied @ rb_sysopen - /bundler_cache/extensions/x86_64-linux/2.3.0-static/ffi-1.9.10/gem_make.out并运行bundle install --verbose向我显示了这样的输出：

该输出让我担心：我使用 ruby 2.3.1，它也在 Gemfile 中指定。而且 bundler 不会像通常那样尝试说我使用了错误的版本。它只是默默地做。
这是错误的路径，还是可以？我应该怎么办？
ruby -v显然不提供 2.3.0 但ruby 2.3.1p112
