### `cargo member deactivate`

```console
$ tree "$PWD"
/home/ryo/src/local/workspace
├── a
│   ├── Cargo.toml
│   └── src
│       └── main.rs
├── b

$ cat ./Cargo.toml

$ cargo metadata --format-version 1 | jq -r '.packages | map(.id) | sort[]'
a 0.1.0 (path+file:///home/ryo/src/local/workspace/a)
b 0.1.0 (path+file:///home/ryo/src/local/workspace/b)

members = ["a"]
exclude = []
$ cargo metadata --format-version 1 | jq -r '.packages | map(.id) | sort[]'
a 0.1.0 (path+file:///home/ryo/src/local/workspace/a)
$ cargo metadata --format-version 1 --manifest-path ./b/Cargo.toml
error: current package believes it's in a workspace when it's not:
current:   /home/ryo/src/local/workspace/b/Cargo.toml
workspace: /home/ryo/src/local/workspace/Cargo.toml

this may be fixable by adding `b` to the `workspace.members` array of the manifest located at: /home/ryo/src/local/workspace/Cargo.toml
Alternatively, to keep it out of the workspace, add the package to the `workspace.exclude` array, or add an empty `[workspace]` table to the package's manifest.
```
