"sls dynamodb start" throws spawn java ENOENT

running on Mac, I've created a basic serverless service using the aws-nodejs template:

serverless create --template aws-nodejs --path TestService

After that I used the following commands to add serverless local:

npm install serverless-dynamodb-local
serverless dynamodb install

No matter what I do, I can't get dynamodb-local to start. When I run 

serverless dynamodb start

I get the following error:

Error: spawn java ENOENT
at _errnoException (util.js:992:11)
at Process.ChildProcess._handle.onexit (internal/child_process.js:190:19)
at onErrorNT (internal/child_process.js:372:16)
at _combinedTickCallback (internal/process/next_tick.js:138:11)
at process._tickDomainCallback (internal/process/next_tick.js:218:9)

Running java --version gives me the following info:

Java 10.0.2 2018-07-17
Java(TM) SE Runtime Environment 18.3 (build 10.0.2+13)
Java HotSpot(TM) 64-Bit Server VM 18.3 (build 10.0.2+13, mixed mode)

I'm using Node 8.11.4 with serverless 1.30.1. Aws-sdk is also installed and I've setup my profile.

Thanks

serverless-dynamodb-offline seems to be unmaintained now. Swapping to serverless-dynamodb worked for me, as per this comment

In my opinion it's better to go with "serverless-dynamodb" instead of "serverless-dynamodb-local". Actually that's a fork from dynamodb-local only. Here is the documentation for migrating it.

https://github.com/raisenational/serverless-dynamodb#migrating-from-serverless-dynamodb-local

You need java installed in your system in both of the case. Use this command if you're a ubuntu user for installing java.

sudo apt-get install openjdk-8-jdk

Need to setup java home env variable as well.

Make sure you have installed jre to run dynamodb jar. Otherwise this error will be thrown.

Following the advice on serverless-dynamodb-local/issues/195, I just ran sls dynamodb install --localPath ./bin and Dynamodb installed correctly. Running serverless offline start then worked without error.

Apparently there is a bug with version [email protected].

issue on github

I've downgraded to version 0.2.30 by using

npm uninstall serverless-dynamodb-local
sls dynamodb uninstall

npm install [email protected]
sls dynamodb install
