尝试在rails项目中安装mysql2时出现PGP关键问题
<p>我正在尝试在本地安装 Rails 项目的所有 gem。</p>
<p>我的 mysql2 有问题。当我尝试安装它时，出现以下错误：</p>

<p>然后我尝试运行 <code>pacman -Syu</code>，但也出现相同的错误，并且没有要求我导入 PGP 密钥。</p>
<p>因此，我尝试根据 MSI 密钥环 GitHub 中的 pacman-key --add </code> 手动导入密钥。然后，我使用 <code>pacman-key --edit-key</code> 将信任更改为 Ultimate。</p>
<p>但是现在，我遇到了另一个错误：</p>

<p>我不知道我是否以这种方式添加了错误的密钥，或者错误是否来自其他原因。我已经为此苦苦挣扎了好几天，我有点迷失了。有人可以帮忙吗？</p>
