I’d a local copy of n8n using npm. Based on an article about IIS deployment, I’d executed “npm build run” as per the guide but encountered the following error:

n8n-npmbuild
n8n-npmbuild915×357 56.3 KB

The following recorded in the log file.

and seems related to package.json below:

“build”: “tsc”,
“dev”: “concurrently -k -n "TypeScript,Node" -c "yellow.bold,cyan.bold" "npm run watch" "nodemon"”,
“postpack”: “rm -f oclif.manifest.json”,

“typeorm”: “ts-node ./node_modules/typeorm/cli.js”,
“watch”: “tsc --watch”
},
“types”: “dist/src/index.d.ts”,
“version”: “0.78.0”

I’ve typescript 3.9.7. Any idea? Thanks.

hm does honestly not look like TypeScript is installed properly neither globally nor as part of n8n else it should not display the error that “tsc” is not known. So I would look into that again.

Here is a guide about how to set up n8n locally for development:

If you do not want to develop for n8n and rather just want to run it, TypeScript should not be needed at all. In this case a npm install n8n -g should be enough.
