I'm using macOS. I had a few versions of yarn installed with Homebrew, which I uninstalled with <code>brew uninstall --force yarn</code>. I then installed the latest version 1.7.0 of Yarn using Homebrew <code>brew install yarn</code>

But still when I ran <code>which yarn</code>, it returned /Users/Me/.yarn/bin/yarn, and <code>yarn --version</code> returned 0.24.6. There was no mention of Yarn in ~/.bash_profile, but my ~/.bashrc file contained the line <code>export PATH="$HOME/.yarn/bin:$PATH"</code> indicating that I must have previously installed Yarn globally, but I only wanted to use the latest version that I just installed with Homebrew.

So I uninstalled Yarn globally by running <code>npm uninstall -g yarn; rm -rf ~/.yarn</code>, then editing the file ~/.bashrc by changing the line to <code>export PATH="/usr/local/bin/yarn:$PATH"</code> and running <code>source ~/.bashrc</code> to update the PATH in the terminal session. Then when I ran <code>which yarn</code> it returned /usr/local/bin/yarn, and when I ran <code>yarn --version</code> it returned
1.7.0

I tried the Homebrew and tarball points from <a href="https://stackoverflow.com/a/45914006/5285297">the post by sospedra</a>. It wasn't enough.

I found yarn installed in: <code>~/.config/yarn/global/node_modules/yarn</code>

I ran <code>yarn global remove yarn</code>. Restarted terminal and it was gone.

Originally, what brought me here was yarn reverting to an older version, but I didn't know why, and attempts to uninstall or upgrade failed.

When I would checkout an older branch of a certain project the version of yarn being used would change from <code>1.9.4</code> to <code>0.19.1</code>.

Even after taking steps to remove yarn, it remained, and at <code>0.19.1</code>.

On my Mac neither of these regular methods to uninstall Yarn worked:

brew: <code>brew uninstall yarn</code>

npm: <code>npm uninstall -g yarn</code>

Instead I removed it manually by typing <code>rm -rf ~/.yarn</code> (thanks user elthrasher) and deleting the two symbol links yarn and yarnpkg from <code>usr/local/bin</code>.
Afterwards <code>brew install yarn</code> gave me the latest version of Yarn.

<hr>

Background: The fact that I had a very outdated version of Yarn installed gave me utterly incomprehensible errors while trying to install additional modules to a project set up with Vue CLI Service and Vue UI, which apparently uses Yarn 'under the hood'. I generally use NPM so it took me a while to figure out the cause for my trouble. Naturally googling error messages produced by such module incompatibilities presented no clues. With Yarn updated everything works just perfectly now.

I couldn't uninstall yarn on windows and I tried every single answer here, but every time I ran <code>yarn -v</code>, the command worked. But then I realized that there is another thing that can affect this.
If you on windows (not sure if this also happens in mac) and using <a href="https://github.com/coreybutler/nvm-windows" rel="nofollow noreferrer">nvm</a>, one problem that can happen is that you have installed nvm without uninstalling npm, and the working <code>yarn</code> command is from your old yarn version from the old npm.
So what you need to do is follow <a href="https://github.com/coreybutler/nvm-windows#uninstall-existing-npm" rel="nofollow noreferrer">this step from the nvm docs</a>
<blockquote>
You should also delete the existing npm install location (e.g. &quot;C:\Users&lt;user&gt;\AppData\Roaming\npm&quot;), so that the nvm install location will be correctly used instead. Backup the global npmrc config (e.g. C:\Users&amp;lt;user&gt;\AppData\Roaming\npm\etc\npmrc), if you have some important settings there, or copy the settings to the user config C:\Users&amp;lt;user&gt;.npmrc.
</blockquote>
And to confirm that you problem is with the old <code>npm</code>, you will probably see the <code>yarn.cmd</code> file inside the <code>C:\Users\&lt;user&gt;\AppData\Roaming\npm</code> folder.

blocks|key|3818659|text|如果是随npm一起安装的，请尝试“npm+uninstall+-g+yarnpkg”(全局)或“npm+uninstall+yarnpkg”(本地)。|type|unstyled|depth|inlineStyleRanges|offset|length|style|BOLD|CODE|entityRanges|data|3818660|这对我来说很管用。|3818661|如果这仍然不起作用，并且你用npm安装了它，|3818662|执行"npm+list+-g“检查是否全局安装，如果是本地安装，则执行"npm+list”。|3818663|希望这对任何有这个问题的人有所帮助。:D|3818664|编辑:发现一些东西，如果你用.msi可执行文件安装yarn，你必须用普通的windows方式安装它。|3818665|entityMap^0|4|3|H|O|1C|L|0|0|0|3|B|10|8|0|0|0^^$0|@$1|2|3|4|5|6|7|S|8|@$9|T|A|U|B|C]|$9|V|A|W|B|D]|$9|X|A|Y|B|D]]|E|@]|F|$]]|$1|G|3|H|5|6|7|Z|8|@]|E|@]|F|$]]|$1|I|3|J|5|6|7|10|8|@]|E|@]|F|$]]|$1|K|3|L|5|6|7|11|8|@$9|12|A|13|B|D]|$9|14|A|15|B|D]]|E|@]|F|$]]|$1|M|3|N|5|6|7|16|8|@]|E|@]|F|$]]|$1|O|3|P|5|6|7|17|8|@]|E|@]|F|$]]|$1|Q|3|-4|5|6|7|18|8|@]|E|@]|F|$]]]|R|$]]

Try "<code>npm uninstall -g yarnpkg</code>"(global) or "<code>npm uninstall yarnpkg</code>"(local) if you installed it with npm. 
That's what worked for me. 
If that still doesn't work and you installed it with npm, do "<code>npm list -g</code>" to check if you installed it globally or "<code>npm list</code>" if you installed it locally. Hope that helps anyone having this problem. :D

EDIT: Found something if you installed yarn with .msi executable you have to install it the normal windows way.

Incase of windows, after executing <code>npm uninstall -g yarn</code>, still if yarn did not uninstalled, then go to "C:\Users\username\AppData\Local" and remove the yarn folder. Close the cmd and reopen the cmd and execute <code>yarn</code> . it will give you message <code>'yarn' is not recognized as an internal or external command,

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

How can I uninstall yarn? I've used it for a react-native project and now whenever I move the code out of <code>index.ios.js</code> or <code>index.android.js</code> it throws an error so I'd like to just use npm but whenever I initialize a react-native project it defaults to yarn. I tried <code>npm uninstall yarn</code> but that didn't work. Thanks.

如何卸载纱线？我曾将它用于react-native项目，现在每当我将代码移出index.ios.js或index.android.js时，它都会抛出一个错误，所以我想只使用npm，但是每当我初始化react-native项目时，它默认使用yarn。我试过npm uninstall yarn，但不起作用。谢谢。
