Autorest: Unable to start AutoRest Core

[JacobVoller]

I am trying to run AutoRest, which I've done several times before, but it's started failing. Here's my command and the failure output. Has anyone else seen any issues similar before?

autorest --input-file=http://localhost:56689/swagger/v1/swagger.json --csharp --output-folder=../Ares --namespace=SPX.ServiceClient.Ares --output-file=AresClient.cs --sync-methods=none --debug --verbose

Looks like my node.js was out of date after a recent update.

1. Install the latest version of node.js (autorest readme suggests 10.15.x) and included the npm install option (on by default): https://nodejs.org/en/download/
2. Cleared the global package cache npm cache clean -f
3. Deleted everything in C:\Users\<profile>\AppData\Roaming\npm
4. Installed again npm install -g autorest

Installing newer version of node v10.9.0 worked for me

Updating Node to v10.9.0 worked for me

Sorry to raise this again, but I have not been able to get past this for a couple of days. I have tried different versions, tried to install nodejs via nvm, choco and msi installer. Always the same error trying to use autorest.

@kitzmark if you still have no luck resolving the installation issue, you may consider the following open-source alternatives for the time being:

• NSWag: https://github.com/RicoSuter/NSwag
• OpenAPI Generator: https://github.com/OpenAPITools/openapi-generator

Sorry to say it out loud but there are always little issues (installation, spec, etc) with autorest that make it pretty much unusable.

I get exactly the same error in app.js at line 233

When an application crashes when you are just trying to run --version ... that's a bad sign for me. I appreciate all the hard work but this tool could use some work. Unfortunately, I don't think any of the other code generators support Azure functions though so I really need this.
