在作业 Circle Ci 中使用 Blackbox 时出现错误“gpg：解密失败：无密钥”答案

【问题标题】：Error "gpg: decryption failed: No secret key" when using Blackbox in job Circle Ci在作业 Circle Ci 中使用 Blackbox 时出现错误“gpg：解密失败：无密钥”

【问题描述】：

我有这个工作流程/工作Circle Ci：

build:
docker:
  - image: circleci/python:3.7
environment:
  PIPENV_VENV_IN_PROJECT: true

steps:
  - checkout
#other stuff here ->  installing dependencies
  - run:
      name: Running blackbox
      command: |
        git clone https://github.com/StackExchange/blackbox.git
        cd blackbox && sudo make symlinks-install && cd ..
        echo "Importing key"
        echo -e "$GPG_KEY_CI" | gpg --import
        blackbox_postdeploy

当管道运行时，错误 "gpg: decryption failed: No secret key" 卡住了将近 3 个小时。我已将 GPG_KEY_CI 设置为 Circle Ci 上的环境变量，并以“echo gpg --list-secret-keys”进行了一些测试，以检查是否导入了密钥（私钥）。所以，一切看起来都是正确的。

这是输出：

【解决方案1】：

3 小时后，我意识到导出的密钥带有保护私钥的密码。因此，只需按照以下步骤再次导出私钥：

1) 先列出获取指纹的按键：

>> gpg --list-secret-keys

/Users/xxxxxx/.gnupg/pubring.kbx
--------------------------------

sec   rsa2048 2019-11-16 [SC] [expires: 2021-11-15]
      FED8634xxxxxxxxxxxxxxxxxxxxxx1E4C7020D9 <====== fingerprint
uid           [ultimate] Circle Ci <xxxx+circleci@gmail.com>
ssb   rsa2048 2019-11-16 [E] [expires: 2021-11-15]

2) 从您的私钥中删除通行证。当 GnuPG 提示输入新密码时，只需将其留空并按 Enter（两次）：

>> gpg --edit-key <fingerprint>
passwd
save

3) 再次将私钥导出到剪贴板（pbcopy 将标准输入复制到剪贴板）：

>> gpg -a --export-secret-keys <fingerprint> | cat -e | sed 's/\$/\\n/g' | pbcopy

4) 替换 Circle Ci 环境变量上的键
