上記のサイトを参考にcloud-sdkを64bit版macOSにインストールしましたが、

./google-cloud-sdk/install.sh

を実行すると

と表示されて正常にPATHを追加することができません。エラーメッセージの内容を検索して、色々と試してみましたが、情報が古いものが多く、意図する結果になりませんでした。

どなたかご教示していただけないでしょうか?

Answer 1

僕もいま同じ目に合っていたのでググっていたところです。
僕のケースは以下で解決したので参考までに：

$ brew upgrade openssl
Updating Homebrew...
==> Auto-updated Homebrew!
Updated 1 tap (homebrew/core).
==> New Formulae
gobo

Warning: openssl 1.1.1d already installed

$ ls /usr/local/Cellar/openssl
1.0.2s

$ brew switch openssl 1.0.2s
Cleaning /usr/local/Cellar/openssl/1.0.2s
Opt link created for /usr/local/Cellar/openssl/1.0.2s

$ gsutil help                 


Updates are available for some Cloud SDK components.  To install them,
please run:
  $ gcloud components update
.
.
~省略~

.

動いた！という感じです。
