如果在删除~/后仍然得到错误。Yarn文件找不到，不要忘记删除Yarn rc文件:

rm ~/.yarnrc.yml 

如果你像这样在全球安装纱线

$ sudo npm install -g yarn

在终端中运行即可

$ sudo npm uninstall -g yarn

现在在运行Ubuntu的本地机器上测试。完美的工作!

Windows:

我需要做这些步骤，以完全去除纱线从系统。

Go to add or remove programs and then search for yarn and uninstall it(if you installed it with the .msi) npm uninstall -g yarn (if you installed with npm) Remove any existing yarn folders from your Program Files (x86) (Program Files (x86)\Yarn). Also need to delete your Appdata\local\yarn folder ( type %LOCALAPPDATA% in the run dialog box (win+R), it opens a local folder and there you'll find the yarn folder to delete) Finally,check your user directory and remove all .yarn folder, .yarn.lock file, .yarnrc etc ( from C:\Users\<user>\)

windows用户:

NPM卸载yarn

Mac用户:

$ NPM卸载yarn

它将完全为您的系统除去纱线。

如果在你的系统上，Yarn是由Node.js通过corepack提供的，那么，你可以选择你想要使用的Yarn版本，如下所述:
