一些背景信息：我是一个项目的维护者，该项目使用gnupg2框架的一部分来用 PGP 公钥加密数据，这样如果我们的服务器被攻破，数据就无法被读取，我的 CI 脚本一直运行良好，直到今天我收到一个奇怪的错误消息：
设备的 ioctl 不合适
我通过在我的 CI 脚本中添加以下行解决了这个问题（有效）
export GPG_TTY=$(tty)
但是我现在遇到了一个问题，它只是随机引发错误：
构建 skey 数组时出错：没有此文件或目录
有人知道为什么会发生此错误或无法找到哪个文件或目录吗？我在网上发现以下目录可能丢失或具有无效权限，但似乎没有做任何事情：
$ mkdir -p ~/.gnupg/private-keys-v1.d
$ chmod 700 ~/.gnupg/private-keys-v1.d
以下是我的 CI 运行器的输出：
$ export GPG_TTY=$(tty)

我按如下方式设置了我的docker：
$ docker pull python:latest
$ docker create python:latest --name python
$ docker run -it python /bin/bash
以下是我去年发现此错误的最新位置：
答案1
后来发现这是 GNUPG2 新版本的问题，我通过添加标志--batch来修复了这个问题gpg --import（基于这个问题）
固定代码行：
echo "$GPG_PRIVATE_KEY" | gpg --batch --import
