Yup, when you do gem install, it will search the current directory first, so if your .gem file is there, it will pick it up. I found it on the gem reference, which you may find handy as well:
是的，当你进行gem安装时，它会先搜索当前目录，所以如果你的。gem文件在那里，它会把它捡起来。我在宝石参考上找到了它，你也会发现它很方便:
gem install will install the named gem. It will attempt a local installation (i.e. a .gem file in the current directory), and if that fails, it will attempt to download and install the most recent version of the gem you want.
gem安装将安装命名的gem。它将尝试本地安装(即当前目录中的.gem文件)，如果失败，它将尝试下载并安装您想要的最新版本的gem。

Also, you can use gem install --local path_to_gem/filename.gem
此外，还可以使用gem安装——本地path_to_gem/filename.gem。
This will skip the usual gem repository scan that happens when you leave off --local.
这将跳过通常的gem存储库扫描——本地的。
You can find other magic with gem install --help.

you can also use the full filename to your gem file:
您也可以使用完整的文件名到您的gem文件:
gem install /full/path/to/your.gem
this works as well -- it's probably the easiest way
这也行得通——这可能是最简单的方法。

If you create your gems with bundler:
如果你用bundler创造你的宝石:
# do this in the proper directory
bundle gem foobar
You can install them with rake after they are written:
你可以在它们写完后用耙子把它们安装好:
# cd into your gem directory
rake install
Chances are, that your downloaded gem will know rake install, too.
很有可能，您下载的gem也会知道rake安装。

if you download the project file from github or other scm host site, use gem build to build the project first, so you can get a whatever.gem file in current directory. Then gem install it!
如果您从github或其他scm主机站点下载项目文件，请使用gem build首先构建项目，这样您就可以获得任何东西。当前目录中的gem文件。然后gem安装它!

If you want to work on a locally modified fork of a gem, the best way to do so is
如果你想在一个本地修改的宝石叉上工作，最好的方法是。
gem 'pry', path: './pry'
宝石“撬”,路径:“。/撬”
in a Gemfile.
Gemfile。
... where ./pry would be the clone of your repository. Simply run bundle install once, and any changes in the gem sources you make are immediately reflected. With gem install pry/pry.gem, the sources are still moved into GEM_PATH and you'll always have to run both bundle gem pry and gem update to test.
…其中。/pry将是存储库的克隆。简单地运行bundle安装一次，您所做的gem源的任何更改都会立即反映出来。与宝石安装撬/撬。gem，源仍然被移动到GEM_PATH中，你将总是需要运行两个bundle gem pry和gem更新来测试。
