M1なMac MiniでFirebase emluatorを動かす

最近ずっと使っていたMacBookProが歪んできていて、修理出さないとヤバそうな雰囲気なのでとりあえずMac Miniに買って開発環境を作ってる。

普通に既存のプロジェクトをgit cloneしてきて、npm(yarn) installすれば動くだろうと思ってたら動かない…

$ firebase emulators:start

firestore-dubug.log を確認してみるとJavaがないと言われてた(笑)

The operation couldn’t be completed. Unable to locate a Java Runtime.

M1 MacにJavaを入れる

Azul SystemsからJDK11を落としてくればよさそう。



これで再度Firebase emulatorを実行すると起動することができる。
