1st - i downloaded yarn from his website <a href="https://classic.yarnpkg.com/en/docs/install#windows-stable" rel="nofollow noreferrer">yarn</a>

I removed my previous solution as I somehow got hung up on the uninstalled node_modules part and presented a solution that probably wouldn't have been relevant. Here is an alternate solution that might work for you...
Open a new terminal and run node -v and then <code>npm -v</code> to make sure you are running compatible versions: &quot;Node 8.9 or higher, together with NPM 5.5.1 or higher&quot;
Uninstall your current Global Angular cli <code>npm uninstall -g @angular/cli</code>
Run npm cache verify
Re-Install Angular CLI npm install -g @angular/cli@latest
Close your terminal window (just because).
Open a new terminal window, browse to where you want your new project and try the 'ng new` command again.

Angular 9 <code>ng new myapp</code> gives error The Schematic workflow failed......

Firstly, uninstall Angular: <code>npm uninstall -g @angular/cli</code>

After uninstall, you should do clean Angular cache: <code>npm cache clean --force</code>

After this, you should do re-install Angular globally: <code>npm install -g @angular/cli</code>

And check the version: <code>ng --version</code>

Now you can create your app: <code>ng new your-app</code>

Here is the simple way, i am sure it will help because this is the error with package installation failed.
Skip node packages for now and use this command to create new app.

I had the same problem, after a lot of search and two day of trying many ways, I finally solved my problem by installing codelyzer.
first run this command in cmd:

<pre><code>npm install -g codelyzer

then run:

<pre><code>ng new yourProject

<li>Open a new terminal window, browse to where you want your new project and try the 'ng new` command again.</li>

blocks|key|561930|text|出现此问题的主要原因是npm缓存仍然保持此错误。你所需要做的就是强制清理npm缓存，并尝试再次创建应用程序。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|561931|npm+cache+clean+--force

This issue arises mostly because of the npm cache still keeping this error. All you need to do is to force clean the npm cache and try creating your app again.
<pre><code>npm cache clean --force
ng new myapp
</code></pre>

blocks|key|44786|text|我也有同样的错误。在重新安装角度CLI之前，您必须检查您的互联网连接及其速度。在我的例子中，错误的发生是因为我的互联网连接中断了。在我解决了连接问题后，我可以解决这个问题。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|44787|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I got the same error. Before you reinstall the Angular CLI you have to check your internet connection and its speed. In my case, the error has occurred because my internet connection was interrupting. I could resolve that issue after I fixed my connection issue.

blocks|key|44789|text|确保cli在安装过程中很小，并且包看起来像@angular/cli。为了解决这个问题，我在一些教程中遵循了这一点。|type|unstyled|depth|inlineStyleRanges|offset|length|style|BOLD|CODE|entityRanges|data|44790|entityMap^0|2|3|L|C|0^^$0|@$1|2|3|4|5|6|7|I|8|@$9|J|A|K|B|C]|$9|L|A|M|B|D]]|E|@]|F|$]]|$1|G|3|-4|5|6|7|N|8|@]|E|@]|F|$]]]|H|$]]

Ensure cli is in a small case and package looks like <code>@angular/cli</code> during installation. I have followed this in some tutorial to solve this issue.
