我最近有一个由第三方为我开发的RoR应用程序,现在我要自己添加我想要的未来功能。它在Heroku上工作,但是当我尝试在localhost:3000上运行它时,我得到一个ArgumentError。我没有改变任何代码,我只是把它从github上拉出来,并试图在本地开发服务器上运行它来实现新的变化。我问过他们这个问题,但他们不确定原因,所以……
我们运行的是ruby 1.9.2, rails 3.0.7
每当我尝试在我的网站上保存一个项目时,或者每当.save在对象上被调用时,我都会得到一个ArgumentError,错误的参数数量(2为0)。

来自projects_controller的代码,第24行是if语句
def create
@project = Project.new(params[:project])
@project.memberships.build(:user_id => current_profile.id, :pending => false)
if @project.save
redirect_to destination, :notice => 'Project was successfully created.'
else
build_project_associations_for_nested_forms
render :action => 'new'
end
end
我在这方面有点新手,所以我不太确定还需要什么来确定问题。
您是否尝试过运行除WEBrick之外的其他东西(假设您正在使用它)?尝试安装Thin (gem install Thin),看看问题是否仍然存在。
确保你已经获得了所有必需的gem,运行bundle install:
bundle install
