Problems using gdk

Question

I am trying to use GDK (Greengrass Development Kit) for developing IoT Greengrass components.
I've followed by [instruction](https://docs.aws.amazon.com/greengrass/v2/developerguide/create-components.html).   
I've done the next steps:  
init:
> gdk component init --template HelloWorld --language python

Then have changed `gdk-config.json` file:   
```
{
  "component": {
    "com.example.PythonHelloWorld": {
      "author": "SOME",
      "version": "1.0.0",
      "build": {
        "build_system" : "zip"
      },
      "publish": {
        "bucket": "greengrass-component-artifacts",
        "region": "eu-central-1"
      }
    }
  },
  "gdk_version": "1.0.0"
}
```
And after `build` command I got an error:
```
aleksandr@myPC:~/test/test$ gdk component build
[2021-12-23 10:34:34] INFO - Getting project configuration from gdk-config.json

=============================== ERROR ===============================

```

Can anyone please help me? What I have done wrong?

Python 3.8.0 was used.

Answer

Hello,
I have successfully developed IoT Greengrass components using Greengrass development kit. Please find below steps I have followed

1. Installed GDK CLI
2.Ran below commands to create components folders
	mkdir ~/greengrassv2
	cd ~/greengrassv2
3.Create and change to a component folder where the GDK CLI downloads the template or community component
	mkdir HelloWorld-python
	cd HelloWorld-python
4. To create a component folder from a template, run the following command.
	gdk component init --template HelloWorld --language python
python --version 
2.7.16
python3 --version
Python 3.9.9

5. gdk-config.json and recipe.yaml

**gdk-config.json **

{
  "component": {
    "com.example.PythonHelloWorld": {
      "author": "Namratha",
      "version": "NEXT_PATCH",
      "build": {
        "build_system": "zip"
      },
      "publish": {
        "bucket": "bucket-name",
        "region": "us-east-1"
      }
    }
  },
  "gdk_version": "1.0.0"
}

**recipe.yaml**
---
 RecipeFormatVersion: "2020-01-25"

ComponentName: "com.example.PythonHelloWorld"

ComponentVersion: "1.0.0"

ComponentDescription: "This is simple Hello World component written in Python."

ComponentPublisher: "Namratha"

ComponentConfiguration:

DefaultConfiguration:

Message: "World"

Manifests:

os: all

Artifacts:

- URI: "s3://bucketname/HelloWorld-python.zip"

Unarchive: ZIP

Lifecycle:

6. Build using below command

gdk component build

Could you please follow above steps and let me know if you are still facing issue? Please share recipe file and steps to reproduce your issue.

Answer

I use Ubuntu 18.04.5 LTS.  
```
python --version
Python 3.8.0
```
I've reinstalled gdk by command:
```
pip uninstall gdk
python3 -m pip install git+https://github.com/aws-greengrass/aws-greengrass-gdk-cli.git
```
Than I've created a component by template:
```
mkdir ~/greengrassv2
cd ~/greengrassv2
mkdir HelloWorld-python
cd HelloWorld-python
gdk component init --template HelloWorld --language python
```
The `gdk-config.json` :
```
{ "component": {"com.example.PythonHelloWorld": {"author": "Alex", "version": "NEXT_PATCH", build": {"build_system": "zip"}, "publish": {"bucket": "jetson-inference-bu", "region": "eu-central-1"}}},  "gdk_version": "1.0.0"}
```
And, after the command `gdk component build -d` I got:
```

Answer

Hi Namratha_K,
Thank you for attention to my problem.
I have tried do the steps from the [guide  ](https://docs.aws.amazon.com/greengrass/v2/developerguide/create-components.html):  
```
mkdir HelloWorld-python
cd HelloWorld-python
gdk component init --template HelloWorld --language python
```
I've edited `gdk-config.json`:
```
{
  "component": {
    "com.example.PythonHelloWorld": {
      "author": "Alex",
      "version": "NEXT_PATCH",
      "build": {
        "build_system": "zip"
      },
      "publish": {
        "bucket": "greengrass-component-artifacts",
        "region": "eu-central-1"
      }
    }
  },
  "gdk_version": "1.0.0"
}
```
And, the `recipe.yaml` looks like:
```
---
RecipeFormatVersion: "2020-01-25"
ComponentName: "{COMPONENT_NAME}"
ComponentVersion: "{COMPONENT_VERSION}"
ComponentDescription: "This is simple Hello World component written in Python."
ComponentPublisher: "{COMPONENT_AUTHOR}"
ComponentConfiguration:
  DefaultConfiguration:
    Message: "World"
Manifests:
  - Platform:
      os: all
    Artifacts:
      - URI: "s3://BUCKET_NAME/COMPONENT_NAME/COMPONENT_VERSION/HelloWorld.zip"
        Unarchive: ZIP
    Lifecycle:
      Run: "python3 -u {artifacts:decompressedPath}/HelloWorld/main.py {configuration:/Message}"
```
After I've launched the command:
```
gdk component build
```
gdk have created directoryes `HelloWorld-python/zip-build` recursivelly. So, I got an error:
```
