NPMの更新が何も

Question

を行いません。

しかし、私が行うときnpm outdatedは多くの時代遅れのパッケージを示しています。

どのようにすべてのパッケージを更新しますか？

Answer 1

npm update --dd出力が最後になぜ言う：この特定のパッケージ、angular/commonで

...not updating @angular/common because it's currently at the maximum version that matches its specified semver range

ルック。 2.0.0に設定されています。つまり、npm は常に特定のバージョンを取得します。パッケージを更新する場合は、セーバー範囲を使用する必要があります。セーバー範囲hereの包括的な一覧を見ることができますが、最も一般的に使用されるのはおそらく~と^です。

は、マイナーバージョンが更新されることを意味します。したがって、バージョン~1.2.1の場合は1.2.xに更新されますが、1.3.0には更新されません。あなたは^1.2.1を持っている場合、それはどの1.x.xリリースに更新ませんが、決して2.0.0になりますので、

^は、メジャーバージョンとマイナーバージョンを更新します。
