I had the same issue on Ubuntu 17.04.
This solution worked for me:
sudo apt remove cmdtest
sudo apt remove yarn
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
sudo apt-get update
sudo apt-get install yarn -y
then
yarn install
result:
yarn install v1.3.2
warning You are using Node "6.0.0" which is not supported and may encounter bugs or unexpected behaviour. Yarn supports the following server range: "^4.8.0 || ^5.7.0 || ^6.2.2 || >=8.0.0"

I had the same issue on Ubuntu 18.04. This was what worked for me:
I removed cmdtest and yarn
sudo apt remove cmdtest
sudo apt remove yarn
Install yarn globally using npm
sudo npm install -g yarn

Note: This solution works well on Ubuntu 16.04, Ubuntu 17.04 and Ubuntu 18.04.
Try to remove the existing cmdtest and yarn (which is the module of legacy black box command line tool of *nix systems) :
sudo apt remove cmdtest sudo apt remove yarn
Install it simple via npm
npm install -g yarn
OR
sudo npm install -g yarn
Now yarn is installed. Run your command.
yarn install sylius
I hope this will work. Cheers!
Edit:
Do remember to re-open the terminal for changes to take effect.

With kudos to all the answers that correctly suggest removing the Ubuntu yarn package and installing Yarn through NPM, here is a detailed answer with explanation (and, be warned, opinions):
The reason for the No such file or directory error from yarn install is that you are not using the "correct" Yarn: the software you get when you install yarn using the Ubuntu software sources is the "yarn" scenario testing tool from the cmdtest blackbox testing suite. This is likely not what you meant as Yarn is also a popular development lifecycle tool for Javascript application (similar to Make, Maven and friends).
The Javascript Yarn tool is not available from Ubuntu software sources but can be installed by NPM (which is another development lifecycle tool that Yarn aims to replace - so that's awkward...).
To make Yarn available in Ubuntu, start by removing cmdtest and its tools:
$ sudo apt purge cmdtest
Then make sure NPM is installed:
$ sudo apt install npm
Then use NPM to install Yarn:
$ npm install -g yarn
Note: using npm install -g will install a Javascript package for your current user account, which should be fine for most purposes. If you want to install Yarn for all users, you can use sudo for the NPM command, but that is not recommended: NPM packages are rarely audited for security in the context of a multi-user operating system and installing some packages might even break when installing them as "root". NPM used to warn against running it with sudo and the main reason it is not doing so today is that it annoys people that use sandboxed "root-like" environments (such as Docker) for building and deploying Javascript applications for single-user servers.

this worked for me
sudo yarn install

TL;DR
// Run these commands (Tested on Ubuntu 17.04 & above) 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 sudo apt-get update && sudo apt-get install yarn
Additional Notes: Check out this official documentation/guide for installing yarn on other Ubuntu versions & to take care of additional cmdtest errors. https://yarnpkg.com/lang/en/docs/install/#debian-stable
If you don't have curl installed you can install it using sudo apt install curl

Installing Yarn for Ubuntu 16.04 (not sure if this will be the same as 14.04 as it's slightly different than zappee's answer for 17.04)
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
curl -sL https://deb.nodesource.com/setup_9.x | sudo -E bash -
apt-get update
apt-get install nodejs
apt-get install yarn
Then from wherever you installed your sylius project (/var/www/mysite)
yarn install
yarn run gulp

For Ubuntu 18.04.4 LTS I just followed the official instructions: https://classic.yarnpkg.com/en/docs/install#debian-stable
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
sudo apt update && sudo apt install yarn
No need to do:
sudo apt remove cmdtest
That is only necessary on Ubuntu 17.04.* I think.
I hope it helps!

Also had this issue (windows), the fix was a complete closure of all terminal instances, then retry.
回答10:
sudo npm install -g yarnpkg
npm WARN deprecated yarnpkg@0.15.1: Please use the `yarn` package instead of `yarnpkg`
so this works for me
sudo npm install -g yarn

My solution was
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
sudo apt-get update && sudo apt-get install yarn
回答12:
I believe all relevant solutions have been provided but here is a subtle situatuion: know that if you don't close and open your terminal again you will not see the effect.
Close your terminal and open then type in your terminal
yarn --version
Cheers!

Tried above steps, didn't work on Ubuntu 20. For Ubuntu 20, remove the cmdtest and yarn like suggested above. Install yarn with below commands:
curl -sL 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
sudo apt update && sudo apt install yarn

Run:
