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>\)

取决于你如何安装它:

酿造:酿造卸载纱线

tarball: rm -rf "$HOME/.yarn"

Npm: Npm卸载-g yarn

Ubuntu: sudo apt-get remove yarn && sudo apt-get purge yarn

拆纱:拆纱

Windows: choco卸载yarn(或去控制面板>添加/删除程序，并从那里卸载它)

Windows用户:

只需使用安装文件(i。e yarn-1.22.4。Msi在我的情况下)卸载纱线。

一旦你打开安装程序，你会得到三个选项，即安装，维修和卸载纱线从你的机器。 选择卸载，它将从你的电脑中删除所有的yarn文件。

在windows的情况下，执行npm uninstall -g yarn后，仍然如果yarn没有卸载，然后转到“C:\Users\username\AppData\Local”并删除yarn文件夹。

关闭cmd并重新打开cmd并执行yarn。它会告诉你“yarn”不是内部或外部命令、可操作程序或批处理文件。

我用的是macOS。我在Homebrew上安装了几个版本的纱线，我用brew uninstall -force yarn卸载了它们。然后，我使用Homebrew brew install Yarn安装了最新版本的1.7.0

但当我运行哪个纱线时，它仍然返回/Users/Me/。Yarn /bin/ Yarn和Yarn——version返回0.24.6。在~/中没有提到Yarn。Bash_profile，但是我的~/。bashrc文件中包含一行export PATH="$HOME/. exe "。yarn/bin:$PATH”表示我以前必须在全球范围内安装了yarn，但我只想使用刚刚在Homebrew中安装的最新版本。

所以我通过运行npm uninstall -g Yarn全局卸载了Yarn;Rm -rf ~/。Yarn，然后编辑文件~/。将bashrc的代码行更改为export PATH="/usr/local/bin/yarn:$PATH"并运行源代码~/。bashrc更新终端会话中的PATH。然后当我运行哪个yarn时，它返回/usr/local/bin/yarn，当我运行yarn——version时，它返回 1.7.0
