2 days ago ,I followed the official website to instal yarn ,but found the version  is 1.3.2 can cannot find a solution to upgrade it to the latest version , even google and stackoverflow cannot help, finanly I fix it on my way:




step  one:

open your terminal , and delete files  rm -f /usr/local/bin/yarnpkg

rm -f /usr/local/bin/yarn

step 2:   remove cacherm -rf ${HOME}/.yarn

step 3:  remove some variable if these variables exist

export PATH="$PATH:`yarn global bin`"


step 4:  install yarn by curl commandcurl -o- -L [url=https://yarnpkg.com/install.sh]https://yarnpkg.com/install.sh[/url] | bash

you will see these










so check your yarn version on your computer 
$ yarn -v

1.3.2

No  Worries,let's continue, type this command againcurl -o- -L [url=https://yarnpkg.com/install.sh]https://yarnpkg.com/install.sh[/url] | bash

step 5.  add this command
export PATH="$PATH:$HOME/.yarn/bin:$HOME/.config/yarn/global/node_modules/.bin"

Now, you can type yarn -v to check your yarn version would be 1.16.0
