"SyntaxError: Unexpected token function" when installing Gauge via npm

[glalejos]

Hi, I'm trying to install Gauge with the command npm --registry http://localhost:39720/repository/npm-group/ install -g @getgauge/cli, but I get the following error:

/opt/node-v6.12.3-linux-x64/bin/gauge -> /opt/node-v6.12.3-linux-x64/lib/node_modules/@getgauge/cli/bin/gauge

I'm using npm 6.6.0, and I can install other packages via npm without problem.

Any idea on what might be wrong?

Thank you,

I guess you need node 8+, since the script uses some ES6 (in this case async) syntax.

If you plan to use gauge-js plugin, then it only works with node 8+.

Thanks @sriv, that moved forward the installation process!.

However it is unable to successfully complete the installation:

I bet this is related to the proxy.

How can I define the proxy in order to complete the installation?

Thank you,

Guillermo

[sriv]

hi @glalejos - can you please try setting the proxy as an environment variable?

[glalejos]

Thanks @sriv. I was missing the http_proxy environment variable - which I was pretty sure was defined, sorry for not double checking before asking - I got another error after that one, but it went away when I connected to a proxyless network at home... The important part is that Gauge is now installed. Thanks again.
