ubuntu安裝yarn

 1、安裝yarn

sudo apt-get update
sudo apt-get upgrade
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 install yarn

驗證

yarn --version

2、換源

yarn config set registry https://registry.npm.taobao.org

提示：如果輸入yarn報錯（There are no scenarios ; must have at least one）則按如下進行升級

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 update
sudo apt install yarn
