在过去的 2 天里，我在将 Rails+React 应用程序部署到 Heroku 时遇到了问题。该问题是间歇性的（有时我可以部署），这让我认为这是 Heroku 连接到纱线注册表的问题。

当我转到注册表https://registry.yarnpkg.com 时，一切似乎都正常。当我转到 Heroku 的状态页面 ( https://status.heroku.com/ ) 时，他们没有说他们有任何问题。

这是我的代码库有问题吗？我应该设置一个纱线镜吗？

下面是我的控制台日志。它总是在某些时候失败，但每次都有不同的包。

-----> Ruby app detected

我已经了解了以下链接中的详细信息，但仍然存在何时使用哪个文件的问题？ https://docs.npmjs.com/files/package-lock.json

升级后我正在尝试使用最新的纱线版本.
我已经跟进了https://yarnpkg.com/en/docs/install#mac-stable说明,但纱线没有真正升级.
运行后brew upgrade yarn:

$ brew upgrade yarn
Updating Homebrew...
Error: yarn 1.9.4 already installed

跑完后yarn --version:

$ yarn --version
1.9.2

有没有办法使用最新版本？
虽然指南说brew upgrade yarn应该自动完成..

似乎有时会npm link在出现yarn link奇怪错误的情况下起作用。我注意到了几次。我以为他们俩都在后台做符号链接-他们在做些不同的事情吗？

是否建议将数字列用作分区键？当我们对数字列分区和字符串列分区进行选择查询时，性能会有什么差异吗？

我今天早些时候试图用纱安装一个包，我明白了

我有在构建时复制资产的代码。我想知道使用Yarn Plug'n'Play执行相同操作的最佳方法是什么，因为 node_modules 不存在。

new CopyWebpackPlugin([
  { from: 'node_modules/pdfjs-dist/cmaps/', to: 'static/cmaps/' },
]),

yarn cache dir告诉我目录，并且在.pnp.js.

  ["pdfjs-dist", new Map([
    ["2.0.943", {
      packageLocation: path.resolve(__dirname, "../../Library/Caches/Yarn/v3/npm-pdfjs-dist-2.0.943-32fb9a2d863df5a1d89521a0b3cd900c16e7edde/node_modules/pdfjs-dist/"),

我应该像以前那样解析文件并复制吗？或者有更好的办法吗？

我是 Yarn 包管理器的新手。我得到低于错误。有人可以帮助我吗？

我正在大学练习使用React和Redux构建应用程序.当我使用Yarn启动服务器时,我收到此错误:

Passing redux store in props has been removed and does not do anything. 
To use a custom Redux store for specific components, create a custom React context with React.createContext(), and pass the context object to React-Redux's Provider and specific components like: 
<Provider context={MyContext}><ConnectedComponent context={MyContext} /></Provider>. 
You may also pass a {context : MyContext} option to connect

我的文件是这些:

index.js

import React from 'react';
import ReactDOM from 'react-dom';
import './index.css';
import ReduxProvider from './redux/ReduxProvider';
import * as serviceWorker from './serviceWorker';

ReactDOM.render(<ReduxProvider …

我不确定这是否是create-react-app或 的问题yarn。

我正在尝试使用create-react-app. yarn它似乎在幕后使用来获取依赖项，但yarn忽略了自己的注册表配置设置并尝试直接从https://registry.yarnpkg.com/下载包。

这是我尝试使用时的输出create-react-app。您可以在最后看到yarn忽略注册表配置设置：

$ npx create-react-app@2.1.2 my-app --verbose --registry "http://myownregistry:1234/"
npm info it worked if it ends with ok
