joh*_*zli 11 javascript node.js typescript reactjs tsconfig
我发现不是很久以前,每当我尝试启动我的应用程序,我收到很多Cannot find name 'require'与Cannot find type definition file for 'node'和Cannot find type definition for 'react-router'
我已经尝试过的一些解决方案是:
1)types: ["node"]在我的 tsconfig.json 中添加一个,如下所示。
2)添加@types/node我的package.json,你们都可以在这里看到。
3)删除node_modules和reing,yarn无济于事。我也删除了 yarn.lock 并且问题仍然存在。
4) 添加一个typeRoots: ["node_modules/@types/node"],这似乎没什么用。

上述 tsconfig 和 package.json 组合产生以下错误:
ERROR in ./src/index.tsx
(5,1): error TS2580: Cannot find name 'require'. Do you need to install type definitions for node? Try `npm i @types/node` and then add `node` to the types field in your tsconfig.
ERROR in /Users/johnli/Documents/portfolio/tsconfig.json
error TS2688: Cannot find type definition file for 'node'.

我注意到的一些奇怪行为是添加types: ["node"]将删除 myCannot find type definition file for 'react-router'但不会删除node. 添加react-router产生用于两个误差node和react-router,以及去除所述types属性完全还产生两个错误node和react-router。
我想避免使用declare var require: any作为解决方案,因为这并不能解决问题的核心,更像是一个补丁。
更多信息应该有用:节点版本是11.6.0和纱线版本是1.13.0
还有其他建议可以让这个工作吗?除了我上面尝试过的解决方案之外,我似乎找不到任何其他解决方案。如果需要,我还可以提供更多信息。谢谢大家!
