AWS SAM - Esbuild Failed: cannot find esbuild

I'm trying out AWS SAM with nodeJS and Typescript using 'sam init', but when I want to build the example hello-world-typescript application using 'sam build', I get the following message:

Building codeuri: C:\RF\GitHub\rf-09-06\hello-world runtime: nodejs14.x metadata: {'BuildMethod': 'esbuild', 'BuildProperties': {'Minify': True, 'Target': 'es2020', 'Sourcemap': True, 'EntryPoints': ['app.ts']}} architecture: x86_64 functions: ['HelloWorldFunction']
Running NodejsNpmEsbuildBuilder:CopySource
Running NodejsNpmEsbuildBuilder:NpmInstall
Running NodejsNpmEsbuildBuilder:EsbuildBundle

Build Failed
Error: NodejsNpmEsbuildBuilder:EsbuildBundle - Esbuild Failed: cannot find esbuild

Any idea how to resolve it?

Thanks!

I was encountering this issue as well. I put sam build as an npm script so that it looks at your project's node_modules.

package.json

{
  ...
  "scripts": {
    "build": "sam build"
  }
}

This way you don't have to install esbuild globally. Then just npm run build or yarn build

You can install esbuild as development dependency and run sam build in package manager (ex: pnpm) scope

example:

pnpm sam build

It can be solved in either of the 2 ways:

Install esbuild globally using npm install -g esbuild
As mentioned in the AWS SAM github issues, move esbuild to non-dev dependency (npm install esbuild) - Since esbuild will bundle your code, it won't be packaged in your Lambda.

PS: latest version of hello-world-typescript has this already corrected as mentioned in point 2.
