Ubuntu 16.04: Error in the terminal

[gusbemacbe]

I installed nodejs before, but when I tried to install cerebro via terminal, I got an error:

$ cd cerebro && yarn && cd ./app && yarn && cd ../
ERROR: There are no scenarios; must have at least one.

Thank you for your attention!

Get rid of the && and try those commands one by one. Which one yields the error?

[gusbemacbe]

It still gave the same error, but I discovered something.

It was prevented by cmdtest installed from Ubuntu. I removed cmdtest and replaced for yarn installed from npm install yarn, after ugrading to nodejs 7.

Unfortunately, after running cd cerebro && yarn && cd ./app && yarn && cd ../, it gave some errors of compatibility and download, Cerebro started, but after closing the terminal, Cerebro app does not start anymore. I saved two texts, one with script-commanded and another without script-commanded via terminal (I selected and copied all) and attach them for you.

Terminal 1 - clean copy of all the terminal
Terminal 2 - copy from script

terminal.txt
terminal2.txt

@gusbemacbe looks like terminal2.txt is cut. Can you attach full version?

Also, still would be better if you can run command-by-command and see where you have an issue:

cd cerebro
yarn 
cd ./app
yarn 
cd ../

Here are the three separated files output from script via terminal.

1 - cd cerebro && yarn.txt
2 - cd ./app && yarn.txt
3 - cd ../ && yarn run dev.txt

I'm running Ubuntu 14.04 and I believe I have the same issue, if I just run yarn I get ERROR: There are no scenarios; must have at least one.

@joseph-zhong you also run yarn from cmdtest, uninstall it with sudo apt remove cmdtest.
