尝试启动rails服务器时出现语法错误

Question

我最近开始从事一个从github克隆的项目。

每次尝试启动rails服务器时，都会出现以下错误：

我的同事也在做这个项目，启动服务器似乎没有任何问题。他正在运行和我一样版本的ruby，rails和WeBrick。

我已尝试将语法从key:更改为：key=

我已经厌倦了多次完全移除和重新安装rvm、ruby和rails，但都没有成功。我也尝试过运行bundle安装，但没有任何帮助。

有人知道出了什么问题吗？

谢谢

Answer 1

看起来像是另一行上的散列语法，在您修复该行之后。检查config/initializers/wrap\u参数。rb我想知道这个项目是否得到了“不”使用新语法的标志？

Answer 2

尝试将哈希值更改为：key=

App::Application.config.session_store :cookie_store, :key => '_BillingMiddleware_session'

配置/初始化器/wrap_parameters.rb

ActionController::Base.wrap_parameters :format => [:json]
