create-react-app 忽略了 yarn 的注册表配置值

Question

我不确定这是否是 create-react-app 的问题或 yarn .

我正在尝试使用 create-react-app .好像用了yarn在引擎盖下获取依赖项，但是 yarn忽略自己的注册表配置设置并尝试直接从 https://registry.yarnpkg.com/ 下载软件包.

这是我尝试使用 create-react-app 时的输出.你可以在最后看到 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
npm info using npm@6.4.1
npm info using node@v10.13.0
npm timing npm Completed in 153ms
npm info ok
npx: installed 63 in 72.714s

我该怎么做才能得到 create-react-app调用 yarn在某种程度上，yarn使用注册表配置值？

Answer 1

我今天遇到了同样的问题并找到了根本原因，有一个 piece of code检查 yarn 配置中的自定义注册表。如果未找到则缓存 yarn.lock安装前将文件(带有指向默认注册表的链接)复制到目标文件夹:

if (yarnUsesDefaultRegistry) {
  fs.copySync(
    require.resolve('./yarn.lock.cached'),
    path.join(root, 'yarn.lock')
  );
} 

当您从命令行运行相同的安装命令时，与生成的锁定文件没有冲突，并且所有安装都可以使用您的 .npmrc 顺利进行。 .将其捕获为 create-react-app 非常棘手。在安装失败时清除锁定文件:)。
我认为这是 create-react-app问题。简单的解决方法是将自定义注册表显式设置为 yarn:

yarn config set registry http://myownregistry:1234 --global

下一次 create-react-app 运行将选取此属性并跳过缓存锁定文件的复制。
