Node.js 18系のnpmでエラー。それ、nvm-windowsのバージョンが原因かも

⇧Shift-JIS「0x5c問題」って可能性を推測してる方がおりましたが、「0x5c問題」ってのがあるのか。

CSVファイルの生成とかで文字コードをShift-JISにしたりしてる例を見たことあるけど、問題ないんかね？

Node.js 18系のnpmでエラー。それ、nvm-windowsのバージョンが原因かも

久々に、nvm-windowsでNode.jsの18系をインストールしてnpmコマンドを実行したら、

ERROR: npm v9.5.1 is known not to run on Node.js v18.16.0. You'll need to upgrade
to a newer Node.js version in order to use this version of npm. This version of

⇧ エラー。

どうやら、

⇧ nvm-windows自体のバージョンを上げる必要があるらしい。

Upgrading nvm-windows

As of v1.1.8, there is an upgrade utility that will automate the upgrade process.

To upgrade nvm-windows, run the new installer. It will safely overwrite the files it needs to update without touching your node.js installations. Make sure you use the same installation and symlink folder. If you originally installed to the default locations, you just need to click "next" on each window until it finishes.

⇧ バージョンが、v1.1.8以上であれば、アップグレード用の実行ファイルが同梱されているらしいのだけど、それ以外の場合は、インストーラーを使えってことみたい。
