バージョン指定置けるキャレットの理解が曖昧だっったので、

^[version]
Caret(キャレット)記号を用いたときです。
major.minor.patchのうち、一番左の0以外の数字のバージョンを更新しないような、更新が可能です。

{
  "dependencies": {
    "foo": "^1.1.1",  // >=1.1.1 and <2.0.0
    "bar": "^0.1.1",    // >=0.1.1 and <0.2.0
    "hoge": "^0.0.1"      // >=0.0.1 and <0.0.2
  }
}

つまり、phpunit/phpunit ^8.5で出たエラーは、

  Problem 1
    - Installation request for sebastian/version (locked at 1.0.6) -> satisfiable by sebastian/version[1.0.6].
    - phpunit/phpunit 8.5.0 requires sebastian/version ^2.0.1 -> satisfiable by sebastian/version[2.0.1].
    - phpunit/phpunit 8.5.1 requires sebastian/version ^2.0.1 -> satisfiable by sebastian/version[2.0.1].
    - phpunit/phpunit 8.5.2 requires sebastian/version ^2.0.1 -> satisfiable by sebastian/version[2.0.1].
    - Conclusion: don't install sebastian/version 2.0.1
    - Installation request for phpunit/phpunit ^8.5 -> satisfiable by phpunit/phpunit[8.5.0, 8.5.1, 8.5.2].

これは

- sebastian/version[1.0.6] のインストールを実行トライ。 
- phpunit/phpunit 8.5.0は、sebastian/version 2.0.1以上が必要。
- phpunit/phpunit 8.5.1は、sebastian/version 2.0.1以上が必要。
- phpunit/phpunit 8.5.2は、sebastian/version 2.0.1以上が必要。
- 結果: sebastian/version 2.0.1はインストールしない。
- phpunit/phpunit ^8.5以上のインストールを実行トライ。

composer show [パッケージ名]で確認してみよう
