Hello World Instructions don't work #545

Open murphye opened 3 years ago

murphye commented 3 years ago

Been a while since I tried es4x, so I went right to the Hello World example. Doesn't seem to work.

Do you have es4x installed as a global npm package? In this example, I'm pulling it as a local dependency that gets generated in the package.json

murphye commented 3 years ago

If you go to this page: https://reactiverse.io/es4x/get-started/hello-world.html#create-a-new-project

It implies that you can simply create a hello-es4x.js and then run es4x hello-es4x.js

I'm also having issues getting the hello world project to work on Windows 10 after installing es4x globally using npm install -g @es4x/create@0.15.0:

Uninstalled es4x 0.15.0 and tried npm install -g @es4x/create, which installs es4x 0.14.0 - now the npm install command works, but start fails like so:

Any workaround?

pmlopes commented 2 years ago

I do see you have Unix like paths in your output. What are you using to install and launch the application? I assume it's not cmd?

I also need to be fair and say that on windows i pretty much only tested CMD.

If you share what's your setup I'll try to get a dev VM to test that mode too.

From what I can tell, it must be a path issue translating from Windows to Unix somewhere.

omg1492 commented 2 years ago

I used GitBash, now switched to cmd with the same observation.

My concern is that after @es4x/create installation, es4x --help ends with error Missing node_modules\.bin\es4x-launcher.jar.

Cleanup: I uninstalled @es4x/create and deleted remaining @es4x directory. 

c:\workspace\sandbox>npm uninstall -g @es4x/create
