set to `1` to have the URL shown. By default, when Corepack is called
explicitly (e.g. `corepack pnpm …`), it is set to `0`; when Corepack is called
implicitly (e.g. `pnpm …`), it is set to `1`.
The default value cannot be overridden in a `.corepack.env` file.
When standard input is a TTY and no CI environment is detected, Corepack will
ask for user input before starting the download.

project. This means that it will always use the system-wide package manager
regardless of what is being specified in the project's `packageManager` field.
- `COREPACK_ENV_FILE` can be set to `0` to request Corepack to not attempt to
load `.corepack.env`; it can be set to a path to specify a different env file.
Only keys that start with `COREPACK_` and are not in the exception list
(`COREPACK_ENABLE_DOWNLOAD_PROMPT` and `COREPACK_ENV_FILE` are ignored)
will be taken into account.
For Node.js 18.x users, this setting has no effect as that version doesn't
support parsing of `.env` files.
- `COREPACK_HOME` can be set in order to define where Corepack should install
the package managers. By default it is set to `%LOCALAPPDATA%\node\corepack`
on Windows, and to `$HOME/.cache/node/corepack` everywhere else.
