前提

Linux 用のクイックスタート  |  Cloud SDK のドキュメント  |  Google Cloud

アーカイブをファイル システム上に展開

の箇所で、「ホームディレクトリをおすすめします」と書いてあったのでそれに従ってインストールした。

自分がWSLを使っていた時は/mnt/c/wslという、Cドライブ直下にwsl というディレクトリをホームディレクトリにしていたので、

最初はこのようなインストールをした

$ tar zxvf google-cloud-sdk-293.0.0-linux-x86_64.tar.gz google-cloud-sdk

がこれでいろいろやっているうちに、 gcloud components update ができないという上述の問題に遭遇した

試したこと

以下のことを全部やってみたけどダメだった

https://stackoverflow.com/questions/49210830/gcloud-components-update-permission-denied https://stackoverflow.com/questions/31220077/gcloud-installation-permission-issue-on-ubuntu-12-04/31247129#31247129

  1. ./google-cloud-sdkディレクトリのパーミッションを自分にする
sudo chown -R $USER ./google-cloud-sdk
  1. .config/gcloudディレクトリのパーミッションを自分にする
sudo chown -R $USER .config/gcloud
  1. sudoをつけて実行してみる
sudo gcloud components update
  1. pythonを3.6にしてみる(それまで3.7がデフォルトだった)
$sudo apt update
$sudo apt install python3.6

$python3.6 --version
Python 3.6.9

.zshrc(または.bashrc)に以下のaliasを追加

alias python=/usr/bin/python3.6

解決

gcloudを/mnt/c/wsl/ ではなく /home/$USER という、WSLのデフォルトのホームディレクトリに入れ直したら解決した

まずはgcloudを削除

Google Cloud SDK のアンインストール  |  Cloud SDK のドキュメント に従って、以下のディレクトリを削除

$gcloud info --format='value(installation.sdk_root)'
# -> /mnt/c/wsl/google-cloud-sdk
$gcloud info --format='value(config.paths.global_config_dir)'
# -> /mnt/c/wsl/.config/gcloud

.zshrcに書き込まれていた以下の記述も削除

# The next line updates PATH for the Google Cloud SDK.
if [ -f '/mnt/c/wsl/google-cloud-sdk/path.zsh.inc' ]; then . '/mnt/c/wsl/google-cloud-sdk/path.zsh.inc'; fi

# The next line enables shell command completion for gcloud.
if [ -f '/mnt/c/wsl/google-cloud-sdk/completion.zsh.inc' ]; then . '/mnt/c/wsl/google-cloud-sdk/completion.zsh.inc'; fi

tarの展開先を /home/＄USER に変更

$ tar zxvf google-cloud-sdk-293.0.0-linux-x86_64.tar.gz /home/$USER/google-cloud-sdk

新しいgcloudのパス

$which gcloud
/home/ludwig125/google-cloud-sdk/bin/gcloud

こうしたら gcloud components update ができるようになった

ちなみに gcloud --quiet components update とするといちいち 【y/N】と聞かれなくなるので便利
