yarn的安装及升级

首先不推荐使用Ubuntu默认的yarn安装,版本太低。

  1. 首先在Ubuntu的源中添加yarn的源地址
    1
    curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add -  
    1
    echo "deb https://dl.yarnpkg.com/debian/ rc main" | sudo tee /etc/apt/sources.list.d/yarn.list

记得分两次输入

  1. 进行安装
    1
    sudo apt-get update && sudo apt-get install yarn

Ubuntu 17.04 默认安装有cmdtest,会影响正常的Yarn安装,请在之前先卸载

1
sudo apt remove cmdtest
  1. 查看版本
    1
    yarn --version

windows安装的时候经常提示

1
There appears to be trouble with your network connection. Retrying...

进行修改源

1
yarn config set registry https://registry.npm.taobao.org

就可以正常安装相应的包了
