javascript - 为什么我的 create-react-app 项目在编译时会输出数千行关于类型的警告？

问题描述

我正在接管一个遗留项目。我主要是一名后端程序员，而不是最新的 JS 构建工具。我试图弄清楚这个项目是如何组合在一起的。该项目使用react-app-rewired。在服务器准备好之前npm run start-js产生大量的输出。在服务器准备好之前的 2 分钟，对于 10s 的数千行，它看起来像这样：

======== Resolving type reference directive 'async', containing file '/vagrant/client/__inferred type names__.ts', root directory '/vagrant/client/node_modules/@types'. ========
Resolving with primary search path '/vagrant/client/node_modules/@types'.

（node_modules 在/vagrant/client/node_modules）

然后它确实成功了，我所有的 JS 都按预期工作。我猜搜索路径或其他东西配置错误。这是怎么回事？这是正常行为吗？这都是关于类型的，还是其他的？

解决方案

这些消息似乎根本不是警告。事实上，他们说该模块已成功解决。

尝试"traceResolution": false,在compilerOptions您的tsconfig.json文件中添加。
