  Installed Gekko for Bash on windows 10

Node gekko --ui
or
nodejs gekko --ui

I get the following error

SyntaxError: Block-scoped declarations (let, const, function, class) not yet supported outside strict mode

please note that in order to get a successful install I had to used the following symlink fix
sudo ln -sT /usr/bin/nodejs /usr/bin/node

• Expected result (what you hoped would happen)

for Gekko to run

• Actual result (unexpected outcome)

I got same problem.

[crypto-kid]

Fixed it !!!

do the following
sudo ln -sf /usr/local/n/versions/node/7.5/bin/node /usr/bin/node

Then

sudo apt-get update
curl -sL https://deb.nodesource.com/setup_9.x | sudo -E bash -
sudo apt-get install -y nodejs
sudo apt-get install -y build-essential

then run
cd Gekko
node gekko --ui

then open http://localhost:3000. in your browser

Now this has worked for me so only hope it works for you !

Basically you need to ensure that the node.js version on your OS is node.js ver 6 and above.

On ubuntu, I did the following:

sudo apt-get install npm
npm install n -g
sudo n latest

Then run
nodejs gekko --ui

you can also use NVM which i've used quite a bit ( because I have other projects that depend on different versions) https://github.com/creationix/nvm/blob/master/README.md
