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

Apparently there is a bug with version serverless-dynamodb-local@0.2.31.

issue on github

I've downgraded to version 0.2.30 by using

npm uninstall serverless-dynamodb-local
sls dynamodb uninstall

npm install serverless-dynamodb-local@0.2.30
sls dynamodb install

  • This should be the accepted answer. Missed this among all the issues on Github: / – Juvaly Aug 21 '18 at 14:11
  • Tried a bunch of solutions, but only this one worked. Thank you! – Myroslav Hryshyn Aug 21 '18 at 14:16
  • Hopefully that plugin gets updated soon. This was hard to find a fix for. Thanks! – Jordan Aug 30 '18 at 03:52

    FYI, I have had `^0.2.35` installed with no problems until today. Turns out `0.2.36` was just released and has the same problem. I am staying on `0.2.35` for the time being and removed the carrot in my `package.json` – Roustalski Jan 28 '19 at 20:33

    I was on `0.2.38` and saw this problem, downgrading to `0.2.37` fixed it... – hwjp Dec 10 '19 at 11:29

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.

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

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.
