I try to install k6 by ''npm install --save @types/k6"
But I met an error when running ‘tsc’
node_modules/@types/k6/global.d.ts:69:9 - error TS2451: Cannot redeclare block-scoped variable ‘console’.
How I can fix this issue?
@CongNguyen I haven’t been able to reproduce this error. See below the installation output.
$ npm install --save @types/k6
npm notice created a lockfile as package-lock.json. You should commit this file.

In any case, if you want to use TypeScript in your k6 scripts, I recommend using the TypeScript project template.

I have another question if I just want to use JS, after enter the cmd below
npm install --save @types/k6
why I can’t use npx to run k6?
npx k6 run ./xxx.js
Do i need to do the webpack? or any example i can follow?
Hey,
k6 isn’t really nodejs, and as such, npx won’t help you in this situation. What you’re installing using npm install --save-dev @types/k6 is only the typescript type information.
If you only want to use js, and don’t want to use any external modules that require transpilation or polyfilling, skipping webpack is totally fine.
- For running with external modules that require webpack, see GitHub - grafana/k6-template-es6: Template repository for bundling test projects into single test scripts runnable by k6
- For running without external modules that require webpack, see Installation and Running k6
Best,
