Serverless Stack

Hey, I’m trying out the `sst start` to develop lambda locally. I run the command and I get the response `Unknown script "start".`

```{
  "name": "infrastructure",
  "version": "0.1.7",
  "private": true,
  "scripts": {
    "test": "sst test",
    "start": "sst start",
    "build": "sst build",
    "deploy": "sst deploy",
    "remove": "sst remove"
  },
  "devDependencies": {
    "@aws-cdk/assert": "1.61.0",
    "eslint": "^7.15.0"
  },
  "dependencies": {
    "@aws-cdk/aws-cognito": "1.61.0",
    "@aws-cdk/aws-dynamodb": "1.61.0",
    "@aws-cdk/aws-iam": "1.61.0",
    "@aws-cdk/aws-s3": "1.61.0",
    "@aws-cdk/aws-sns": "1.61.0",
    "@aws-cdk/aws-sns-subscriptions": "1.61.0",
    "@aws-cdk/aws-sqs": "1.61.0",
    "@aws-cdk/core": "1.61.0",
    "@serverless-stack/cli": "0.4.3",
    "@serverless-stack/resources": "0.4.3",
    "eslint-plugin-import": "^2.22.1"
  }
}```
^^ package.json

what happens if you run
```npx sst start```


the latest versions of the sst libraries are:
```    "@serverless-stack/cli": "0.30.0",
    "@serverless-stack/resources": "0.30.0",```
So your versions look a bit weird

Okay I’ll try upgrading dependencies :+1:

```"@aws-cdk/core": "1.105.0",
"@aws-cdk/assert": "1.105.0",```
These are the supported versions of the AWS components

Thanks not sure how i ended up with these dependencies

Easiest to scaffold an app with
```npx create-serverless-stack@latest my-sst-app```
and take the dependencies from that
