如何使用 knex postgres 创建 FeathersJS 服务

Question

在试用 FeathersJS 时，我尝试按照文档创建两个服务。第一个称为 x，另一个称为 y。

当我用

创建 x 时

~/r/feathers-chat ❯❯❯ feathers generate service
? What kind of service is it? KnexJS
? What is the name of the service? x
? Which path should the service be registered on? /x
? Which database are you connecting to? PostgreSQL
? What is the database connection string?
  postgres://user:password@localhost:5432/feathers_chat

一切正常。

当我创建 y

~/r/feathers-chat ❯❯❯ feathers generate service
? What kind of service is it? KnexJS
? What is the name of the service? y
? Which path should the service be registered on? /y
? Which database are you connecting to? PostgreSQL

抛出以下错误。

events.js:160
  throw er; // Unhandled 'error' event
  ^

当 default.js

中定义了 postgres 连接时，feathersJS 客户端似乎崩溃了

因此，如果我事先创建连接，客户端会在创建第一个服务时崩溃并出现完全相同的错误。

我不明白我做错了什么，如果您能帮助我使用同一个 postgres 数据库创建第二个服务，我们将不胜感激！

原来是feathers-cli@2.2.2有bug，我卸载安装了2.1.1版本就没有问题了。会提示这个错误。
