Theia: Couldn't start browser example under Windows 10

[UdoW]

when I try to start the browser example with yarn run start I got this error:

child_process.js:107
p.open(fd);
^

[akosyakov]

could you print your node version, npm version and yarn version?

[kittaakos]

Also the version of your Python, please. Thanks!

[kittaakos]

could you print your node version, npm version and yarn version?

Maybe we should do it as part of preinstall so we do not have to ask for that each time explicitly. What do you think, @akosyakov?

[akosyakov]

Maybe we should do it as part of preinstall so we do not have to ask for that each time explicitly.

I would like to simplify npm scripts when it is possible, this change will require adding new scripts.

We could try to warn users with engines attribute: https://github.com/theia-ide/theia/issues/553

Or create a bug template for github.

[kittaakos]

will require adding new scripts.

One script, right?
"preinstall": "printversions-or-whatever"

[kittaakos]

If we can achieve this with engine attributes, that is even better.

node: v8.6.0
yarn: 1.0.2
npm: 5.4.2
Python: 2.7.13

[akosyakov]

Seems to be caused by spaces in paths: https://github.com/apparatus/fuge-runner/pull/18

[UdoW]

hmm, no spaces in the node installation nor in theia git clone dir.

Node installation path: /m/tools/nodejs_8_6_0/node
theia path: /m/projects/th1/theia

@kittaakos could this be the issue for #578 ? do you have spaces in the node exec path?
I don't think so looking at the fix more... but just in case...

[UdoW]

How can I find out?

[UdoW]

I have an alias: alias node='winpty node.exe'

[hexa00]

I get the same issue in my windows vm now.

[hexa00]

$ which node
/c/Program Files/nodejs/node

No spaces...

yarn 1.0.2
node 8.3.0
python 2.7.13
npm 5.3.0

[hexa00]

Strangely if I try wdio it starts the backend properly! That's why appveyor is working.

[hexa00]

$ node src-gen/backend/main.js
Starting express on port 'undefined'.
{"name":"Theia","hostname":"DESKTOP-DS0FJTK","pid":1784,"level":30,"msg":"--root-dir= was not present. Falling back to current working directory: 'C:\\Users\\hexa\\src\\theia\\exa

It works with node so must be a problem with theia cli
@akosyakov ^^

[hexa00]

@UdoW could you confirm that this is now fixed ?

[UdoW]

Yes, it works now. Thanks.
