博士TL; //运行这些命令(在Ubuntu 17.04及以上版本上测试) curl - ss https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add - 回显"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

额外提示:查看官方文档/指南，在其他Ubuntu版本上安装yarn &注意额外的cmdtest错误。https://yarnpkg.com/lang/en/docs/install/#debian-stable

如果你没有安装curl，你可以使用sudo apt install curl安装它

这对我很有效

sudo yarn install

我找到了这个解决方案，因为上面的方法都不适合我。 在我的情况下，现有文件和下载文件之间存在冲突，因此为了解决这个问题，我在linux上执行了以下命令。

sudo mv /var/lib/dpkg/info /var/lib/dpkg/info_silent

Sudo mkdir /var/lib/dpkg/info

Sudo apt-get update

Sudo apt-get -f install <xxxx> .使用实例

<xxxx>替换为需要的包

为Ubuntu 16.04安装Yarn(不确定这是否会与14.04相同，因为它与zappee对17.04的回答略有不同)

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

然后从你安装sylius项目的地方(/var/www/mysite)

yarn install
yarn run gulp

下面的步骤对Pop!_OS 20.10 & ubuntu 20.04

Sudo应该删除cmdtest 须藤易脱纱 curl - ss https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add - 回显"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 线安装

我在Ubuntu 17.04上也遇到了同样的问题。

这个解决方案对我很有效:

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

结果:

yarn install v1.3.2
