If local template directory include @, package name & version is broken

[norux]

Describe the bug

I use monorepo in following project directory: Users/user/git/my-project/packages/@myscope/packages-{a,b,c}
And, my cra-template package lay on @myscope's sub-directory.

If I try,

$ create-react-app my-app --template "file:Users/user/git/my-project/packages/@myscope/cra-template-mine"

Receive error Cannot find module: file:Users/user/git/my-project/packages from react-scripts

I found following:

create-react-app/packages/create-react-app/createReactApp.js

Lines 708 to 721 in 759696d

	} else if (installPackage.match(/.+@/)) {
	// Do not match @scope/ when stripping off @version or @tag
	return Promise.resolve({
	name: installPackage.charAt(0) + installPackage.substr(1).split('@')[0],
	version: installPackage.split('@')[1],
	});
	} else if (installPackage.match(/^file:/)) {
	const installPackagePath = installPackage.match(/^file:(.*)?$/)[1];
	const { name, version } = require(path.join(
	installPackagePath,
	'package.json'
	));
	return Promise.resolve({ name, version });
	}

I think else if (installPackage.match(/^file:/)) this condition must be above else if (installPackage.match(/.+@/))

I found this issue falling into same code path as @norux. I use @context dirs often (e.g.; ~/workspaces/{@work,@play}) freely. The templateInfo path/version doesn't get parsed correctly if contains @
