Hello All, I am new to json forms and trying to do initial setup. I have downloaded Jsonforms-master and performed the steps as given but the npm run build is throwing errors. The following is the error I am getting each time I try to build it. Any suggestions on how to resolve it. lerna notice cli v3.22.1 lerna info Executing command in 9 packages: “npm run build” lerna ERR! npm run build exited 1 in ‘@jsonforms/core’ lerna ERR! npm run build stdout: lerna ERR! npm run build stderr: ‘…’ is not recognized as an internal or external command, operable program or batch file. npm ERR! code ELIFECYCLE npm ERR! errno 1 npm ERR! @jsonforms/core@2.4.1-alpha.0 build: `…/…/node_modules/.bin/tsc` npm ERR!

_[Roberto Polli]_ Did you try to run [GitHub - eclipsesource/jsonforms-react-seed: React-based JSON Forms Seed App](https://github.com/eclipsesource/jsonforms-react-seed) ← this app? ---

Hi @narayan2627, the [jsonforms repository](https://github.com/eclipsesource/jsonforms) is for developing on JSON Forms itself. Using `npm ci && npm run init && npm run build` should do the trick. Maybe you need to switch to a more recent node to build successfully. When you only want to consume JSON Forms then you can follow [this tutorial](https://jsonforms.io/docs/tutorial) ---

_[Narayan2627]_ HI @sdirix I have already followed the same steps but still not able to build it. My node version is v12.18.0 and npm version is 6.14.4. Please suggest me if I am doing anything wrong here. And let me know if there is any specific version that I need to use for node. ---

_[Narayan2627]_ Hi @ioggstream I am successfully able to run the seed app but I am trying to build and develop the Jsonforms itself. ---

_[Narayan2627]_ Found out that the latest code is using node.js version 9.11.2 and npm version 6.4.1. I tried using the same and performed npm ci && npm run init && npm run build. Still I see the same error that I mentioned in the post. Got stuck and I am at dead end. Looking for a solution to this. ---

@narayan2627 Are you on Mac/Linux? Sadly our build setup doesn’t work on Windows, see [#752](https://github.com/eclipsesource/jsonforms/issues/752). You could locally edit all the unix-style paths to Windows ones, however I don’t know whether that is enough to get the build running. ---

_[Narayan2627]_ @sdirix Unfortunately I am on Windows 10. I will look into the link and see to fix it. Thanks for the Input.
