Yarn Syntax error on Ubuntu 16 at yarn --version

I installed Yarn on my Ubuntu 16.04 server.

Setup flow:

curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add -
echo "deb https://dl.yarnpkg.com/debian/ stable main" | sudo tee /etc/apt/sources.list.d/yarn.list

and then

sudo apt-get update && sudo apt-get install yarn

Apparently it doesn't end with an error:

...
Processing triggers for libc-bin (2.23-0ubuntu11) ...

But when I run yarn --version I get this error

root@AMS-148750:~# yarn --version
/usr/share/yarn/lib/cli.js:46083
  let {
      ^

SyntaxError: Unexpected token {

    at Module._compile (module.js:410:26)
    at Object.Module._extensions..js (module.js:417:10)

Please let me know how to fix it. Thank you in advance.

There could be another reason for that. Your nodejs version is very old. You just need to upgrade your nodejs with below command (using npm).

sudo npm install -g n

sudo n stable

This will upgrade to latest stable version.

Worked for me.

I've got such error because I'm using nvm but I didn't install any node version :stuck_out_tongue_closed_eyes: nvm list

N/A
iojs -> N/A (default)
node -> stable (-> N/A) (default)
unstable -> N/A (default)

Just install node version which you need, for example nvm install 13.3.0

that is because your node version is incompatible with yarn.Check your node version with node -version if you have an older version of node then upgrade it to latest version by using: curl -sL https://deb.nodesource.com/setup_10.x | sudo -E bash - apt-get install -y nodejs

This looks like a too old nodejs version for the version of yarn installed from the repo. Please check the requirements for the yarn version you installed and make sure your server fulfills them.
