我刚刚用rvm为rails开发设置了一个Linux Mint盒子.我继续生成了一个Rails 5应用程序,设置了mysql连接,添加了cucumber-rails gem然后尝试运行:

rake cucumber

出于某种原因,我遇到了:

I am trying to implement i18next in my react component using the useTranslation hook, but it keeps saying:

Uncaught Error: Test suspended while rendering, but no fallback UI was specified.

Add a <Suspense fallback=...> component higher in the tree to provide a loading indicator or placeholder to display.

我怎样才能添加<Suspense>比我拥有的更高的任何东西？我究竟做错了什么？我该如何解决？当我使用该<Translation>组件时，它似乎工作正常。当然，如果我关闭 Suspense 并尝试自己处理它似乎也可以正常工作，但我认为这违背了目的。我怎样才能使它真正起作用？我的 Fetch 后端是否配置错误？

测试.js

import React, { Suspense, useState, useEffect, lazy } from "react";
import PropTypes from "prop-types";

import i18n from './i18n';
import { useTranslation } …

我想发送一封电子邮件，其中包含返回我的应用程序的深层链接，但我不想对 URL 进行硬编码，否则当我从一个环境移动到下一个环境时，我必须切换它。如何从 ActionMailer 中获取 Web 应用程序的基本 url？例如，我希望能够拥有类似的东西：

<%= base_uri %>listCreate?first=foo&second=bar

在我的测试环境中渲染如下内容：

http://localhost:30000/myApp/listCreate?first=foo&second=bar

以及生产中的以下内容：

http://www.myDomain.com/myApp/listCreate?first=foo&second=bar

当我尝试安装最新的 ruby​​ (3.0.0) 时，它失败并显示：

ruby-build: definition not found: 3.0.0

显然，Ruby 3 已经发布一个多月了，所以我猜团队在为 Apple Silicon (M1) 构建/打包它时遇到了问题，或者还没有人有足够的带宽来这样做。我将如何跟进此事？

我是 ruby​​ on Rails 的初学者
