Question

我想我弄乱了我的一个项目，现在几乎没有任何命令。

最初我通过RVM安装了所有内容。 Gemfile显示rails 4.1.3

过了一段时间后，我想我可能会尝试更新rails并启动了一些其他项目，其中rails版本是4.2.0并且都运行良好。

最近我回到了第一个部署它的项目。当我注意到我无法在我的工作机器上运行任何开发命令时，我正在配置Capistrano。首先我尝试运行服务器，但出现了这个错误：

$ rails server

bin/rails:6: warning: already initialized constant APP_PATH
/home/axl/coding/bfq/bin/rails:6: warning: previous definition of APP_PATH was here
Usage: rails COMMAND [ARGS]

The most common rails commands are:
 generate    Generate new code (short-cut alias: "g")
 console     Start the Rails console (short-cut alias: "c")
 server      Start the Rails server (short-cut alias: "s")
 dbconsole   Start a console for the database specified in config/database.yml
             (short-cut alias: "db")
 new         Create a new Rails application. "rails new my_app" creates a
             new application called MyApp in "./my_app"

In addition to those, there are:
 application  Generate the Rails application code
 destroy      Undo code generated with "generate" (short-cut alias: "d")
 plugin new   Generates skeleton for developing a Rails plugin
 runner       Run a piece of code in the application environment (short-cut alias: "r")

All commands can be run with -h (or --help) for more information.

所以我想也许我用Capistrano搞砸了一些东西所以我回到了分店大师那里但错误仍然存在。

任何rake调用都会返回：

$ rake db:setup
rake aborted!
Gem::LoadError: You have already activated rake 10.4.2, but your Gemfile requires rake 10.3.2. Prepending `bundle exec` to your command may solve this.
/home/axl/coding/bfq/config/boot.rb:4:in `<top (required)>'
/home/axl/coding/bfq/config/application.rb:1:in `<top (required)>'
/home/axl/coding/bfq  fiscal-quadrum/Rakefile:4:in `<top (required)>'
LoadError: cannot load such file -- bundler/setup
/home/axl/coding/bfq/config/boot.rb:4:in `<top (required)>'
/home/axl/coding/bfq/config/application.rb:1:in `<top (required)>'
/home/axl/coding/bfq/Rakefile:4:in `<top (required)>'
(See full trace by running task with --trace)

根据建议预先bundle exec显示另一个错误。例如：

$ bundle exec rake db:setup
rake aborted!
LoadError: cannot load such file -- gserver
/home/axl/coding/bfq/config/application.rb:7:in `<top (required)>'
/home/axl/coding/bfq/Rakefile:4:in `require'
/home/axl/coding/bfq/Rakefile:4:in `<top (required)>'
(See full trace by running task with --trace)

有类似的情况，错误bin/rails:6: warning: already initialized constant APP_PATH与spring gem有关。运行rake rails：update：bin似乎有所帮助但我无法运行它，因为rake根本不起作用。

所以我尝试重新安装RVM。但没有改变。我甚至删除了RVM并安装了Rbenv。但一切都完全一样。

项目内的版本：

$ ruby --version
ruby 2.2.0p0 (2014-12-25 revision 49005) [x86_64-linux]

$ gem --version
2.4.5

$ rake --version
rake, version 10.4.2

$ rails --version
Rails 4.1.6

bundle update执行了一些更新，但在执行rake之后显示与前置bundle exec相同的错误：

$ rake
rake aborted!
LoadError: cannot load such file -- gserver
/home/axl/coding/bfq/config/application.rb:7:in `<top (required)>'
/home/axl/coding/bfq/Rakefile:4:in `<top (required)>'
(See full trace by running task with --trace)

没有什么有用的谷歌搜索LoadError: cannot load such file -- gserver

请帮助我：＆＃39;（

Answer 1

羞辱我。我没有为项目定义ruby本地版本。

使用RVM时：

$ rvm install 2.1.1
$ rvm use 2.1.1

对于Rbenv：

$ rbenv install 2.1.1
$ rbenv local 2.1.1

LoadError：无法加载此类文件--gserver
