Как исправить ошибку пряжи при установке локального пакета?

Question

Я внес некоторые локальные изменения в пакет, который хочу установить с помощью Yarn.

При установке через реестр npm проблем не возникает. Мой package.json выглядит следующим образом:

{
    "private": true,
    "theia": {
        "frontend": {
            "config": {
                "applicationName": "Theia Rust Example"
            }
        }
    },
    "dependencies": {
.....
       "@theia/cpp-debug": "next",

    },
    "devDependencies": {
        "@theia/cli": "next"
    },
    "workspaces": [
      "packages/*"
    ]
}

После запуска yarn я вижу папку node_modules/@theia/cpp-debug. В этой папке есть папка lib, содержащая различные файлы.

Теперь, когда я использую следующий package.json:

{
    "private": true,
    "theia": {
        "frontend": {
            "config": {
                "applicationName": "Theia Rust Example"
            }
        }
    },
    "dependencies": {
.....

    },
    "devDependencies": {
        "@theia/cli": "next"
    },
    "workspaces": [
      "packages/*"
    ]
}

А затем вручную добавьте cpp-debug в качестве локальной ссылки

yarn add file:/root/theia-cpp-extension/packages/cpp-debug --ignore-workspace-root-check

Это тоже удается. Но когда я в следующий раз бегу

yarn theia build

Я получаю сообщение об ошибке:

И теперь внутри папки node_modules / @ theia / cpp-debug есть пустая папка lib.

Что я делаю неправильно?
