I'm experimenting with yarn 2 and faceplanting.
I created a new folder: /projects/yarn2/
As per their install guide https://yarnpkg.com/getting-started I ran
cd /projects/yarn2/
yarn set version berry
yarn init
then (as per their guide https://yarnpkg.com/getting-started/usage )
yarn add react
and got the following error:
Usage Error: The nearest package directory (/projects/yarn2) doesn't seem to be part of the project declared in /projects.
- If the project directory is right, it might be that you forgot to list yarn2 as a workspace.
- If it isn't, it's likely because you have a yarn.lock or package.json file there, confusing the project root detection.
$ yarn add [--json] [-E,--exact] [-T,--tilde] [-C,--caret] [-D,--dev] [-P,--peer] [-O,--optional] [--prefer-dev] [-i,--interactive] [--cached] ...
What am I doing wrong?

The easiest way to fix it is to use git checkout --theirs yarn. lock , and follow up with yarn install again (which can be followup by yarn cache clean to remove any file that wouldn't be needed anymore). This will cause the v1 lockfile to be re-imported.
Setting defaults for yarn init The following config variables can be used to customize the defaults for yarn init : init-author-name. init-author-email. init-author-url.
To solve the error "yarn: command not found", install the yarn package globally by running npm install -g yarn and restart your terminal. If the command fails, run it with sudo and make sure the correct PATH is set in your system's environment variable.
To install dependencies, you have to run yarn install in the root of your directory to install all the dependencies for a project. The dependencies will be retrieved from the package. json file you pushed to version control, and will be stored in the yarn. lock file.
You either don't have package.json or yarn.lock which confuses yarn if the package is added in the workspace or not. Just run the following command and I think your problem must be solved.
cd <folder_name>/<project_name>
touch yarn.lock
yarn
