The following error occurred
when I created a project with the typecript template of createp-next-app
and did the 'next build'.
```shell
It looks like you're trying to use TypeScript but do not have the required package(s) installed.
Please install @types/node by running:
yarn add --dev @types/node
If you are not trying to use TypeScript, please remove the tsconfig.json file from your package root (and any TypeScript files in your pages directory).
```
This issue was resolved by adding @types/node.
So I added @types/node to the devDependencies of the create-next-app typecript template.
Hello! I was using `npx create-next-app --ts` to quickly bootstrap a basic next.js project with Typescript. It bothered me that I got git diff just from running `npm run build` inside the project, because the new notice in the `next-env.d.ts` file.
So I went ahead and updated the `next-env.d.ts` file in [`packages/create-next-app/templates/typescript`](fb67ce9864/packages/create-next-app/templates/typescript/next-env.d.ts) to be exactly how the file looks after running once. (7417ecc09c)
Then I realized that I could probably do the same for all the `next-env.d.ts` that are spread out in the many examples, to make running those examples after cloning them feel a bit smoother. (fb67ce9864)
> However I skipped the [`with-typescript-graphql`](40f85f6d95/examples/with-typescript-graphql) example since that [`next-env.d.ts`](40f85f6d95/examples/with-typescript-graphql/next-env.d.ts (L4-L9)) actually has changes and I couldn't even run `yarn build` in that example, so I'm not sure what will happen with the `next-env.d.ts`. Someone who _gets_ that example will have to fix it I suppose.
This adds a type annotation for the `NextConfig` type to `next.config.js` in the `create-next-app` typescript template.
