Describe the bug

After updating yarn to the latest version and clearing .vscode/pnpify folder I tried to reinstall sdk for vscode and got error that this tool can only be used with projects using yarn pnp.

        throw new Error(`This tool can only be used with projects using Yarn Plug'n'Play`);

To Reproduce

It works in empty folder:

yarn set version berry
yarn dlx @yarnpkg/pnpify --sdk vscode

Environment if relevant (please complete the following information):

• OS: OSX 10.15.5 (19F101)
• Node version v14.4.0
• Yarn version 2.0.0-rc.34

The latest release doesn't include the latest changes which were merged only 2 days ago. Unfortunately, right now, the documentation always points to the latest changes on master. I'll see if there's anything we can do about it.

So, to answer your question:

• in rc.34, you have to do yarn pnpify --sdk (without arguments, here the vscode is interpreted as the CWD instead of a supported editor)
• on master, you have to do yarn pnpify --sdk vscode

@paul-soporan yarn pnpify --sdk works (if @yarnpkg/pnpify is installed locally), thanks.

I tried to build yarn from sources yarn set version from sources and try yarn pnpify --sdk vscode, but I still get the same error, tho without vscode it works.
yarn --version return 2.0.0-rc.34.git.20200611.7de6413a

That's expected, yarn set version from sources only builds the bundle from sources. @yarnpkg/pnpify isn't part of the bundle, but a regular package that you have to install from the registry.

If you want to install PnPify from sources, you have to do:

$ yarn add @yarnpkg/pnpify@yarnpkg/berry#workspace=@yarnpkg/pnpify

This will install the latest @yarnpkg/pnpify right from our repo. Note: This won't work on Windows unless you have rsync installed, since our build scripts use it.
