Ruby Project-未声明某些gem / packages

Question

我使用ruby 24，下载了要处理的ruby项目，并且正在准备ruby环境。我是红宝石的新手... 因此，我下载了ruby 24，并具有以下环境变量：

在％Path％中：C：\ Ruby24-x64 \ bin GEM_HOME：C：\ Users \ user.gem GEM_PATH：％GEM_HOME； C：\ Ruby24-x64 \ lib \ ruby​​ \ gems \ 2.4.0

我在项目根目录上运行了“ gem install bundler”，然后运行了“ bundle install”。

    bundle install
Warning: the running version of Bundler (1.16.2) is older than the version that created the lockfile (1.16.6). We suggest you upgrade to the latest version of Bundler by running `gem install bundler`.

Bundle complete! 9 Gemfile dependencies, 30 gems now installed.
Use `bundle info [gemname]` to see where a bundled gem is installed.
Post-install message from yard:
--------------------------------------------------------------------------------
As of YARD v0.9.2:

RubyGems "--document=yri,yard" hooks are now supported. You can auto-configure
YARD to automatically build the yri index for installed gems by typing:

    $ yard config --gem-install-yri

See `yard config --help` for more information on RubyGems install hooks.

You can also add the following to your .gemspec to have YARD document your gem
on install:

    spec.metadata["yard.run"] = "yri" # use "yard" to build full HTML docs.

--------------------------------------------------------------------------------

但是我在项目中仍然有错误：

对于JRuby，MultiJson，Faraday，我也有同样的错误（每个单词的首字母大写）。

我为ruby 2.4.5设置了项目SDK。
