Question

我将slim gem安装到我自己的自定义目录中，但需要“瘦身”＃39;给我错误。

安装slim：

$ cd /var/www
$ mkdir project
$ cd project/
$ gem install slim -i gems/
Fetching: temple-0.4.0.gem (100%)
Fetching: slim-1.2.2.gem (100%)
Successfully installed temple-0.4.0
Successfully installed slim-1.2.2

$ ls gems/
bin/            doc/            specifications/ 
cache/          gems/           
$ ls gems/gems/

$ ls gems/gems/slim-1.2.2/

$ ls gems/gems/slim-1.2.2/lib/
slim  slim.rb

宝石环境（如果您注意到我向GEM_PATH添加了/var/www/project/gems）：

$ gem env

测试：

$ irb
irb(main):001:0> require 'slim'
LoadError: no such file to load -- slim
    from <internal:lib/rubygems/custom_require>:29:in `require'
    from <internal:lib/rubygems/custom_require>:29:in `require'
    from (irb):1
    from /usr/local/bin/irb:12:in `<main>'

知道什么是错的吗？我在GEM_PATH中添加了/var/www/project/gems但require 'slim'没有加载宝石，为什么会这样？这是rubygems的错误吗？

我在require 'slim'和/var/www/project/index.rb中撰写ruby index.rb时遇到同样的问题。

我衷心建议使用bundler，它不仅可以管理此版本，还可以代表您进行版本固定和部署。

Rubygems没有加载gem
