Cannot find module '@solana-developers/helpers' or its corresponding type declarations

[GiorgosK]

As part of this tutorial https://www.soldev.app/course/intro-to-writing-data there is this line

import { getKeypairFromEnvironment, airdropIfRequired } from "@solana-developers/helpers";

after adding/install with npm i @solana-developers/helpers I still get the following error reported by vscode

Cannot find module '@solana-developers/helpers' or its corresponding type declarations

and when running the ts file

Could not resolve "@solana-developers/helpers"

Even though I can see the package in "node_modules/@solana-developers/helpers"

After a lot of soul searching ended up building the actual installed package

$ cd node_modules/@solana-developers/helpers
$ npm run build

> @solana-developers/helpers@2.2.0 build
> tsup src/index.ts --dts

sh: 1: tsup: not found
$ npm i tsup -D
...
$ npm run build

> @solana-developers/helpers@2.2.0 build
> tsup src/index.ts --dts

After that the initial error was gone

In my case, the lib was fetched from Github, not NPM Probably something went wrong when publishing v2.2.0. So you can skip that issue by specifying a certain version.

npm i @solana-developers/helpers@latest

npm i @solana-developers/helpers@2.2.0

hrm I can't replicate here.

mkdir deleteme
cd deleteme
npm init -y
npm i @solana-developers/helpers
edit runme.ts
npx esrun runme.ts

runme.ts is:

import {
  getKeypairFromEnvironment,
  airdropIfRequired,
} from "@solana-developers/helpers";

console.log(getKeypairFromEnvironment);

The file runs and the function is found and logged.

@GiorgosK what happens when you do this?

@lucky-gru when you say "In my case, the lib was fetched from Github, not NPM" did you run npm i @solana-developers/helpers or install via some other way?

[lucky-gru]

@mikemaccana I tried

npm i @solana-developers/helpers

[mikemaccana]

Do you still get this with 2.3.0?

Please follow these instructions and report results (same as previous)

mkdir deleteme
cd deleteme
npm init -y
npm i @solana-developers/helpers
edit runme.ts
npx esrun runme.ts

runme.ts is:

import {
  getKeypairFromEnvironment,
  airdropIfRequired,
} from "@solana-developers/helpers";

console.log(getKeypairFromEnvironment);

Haven't gotten any reply to this, it seems like it's dead. Closing...
