也许smb有同样的错误？
非常感谢您的回答 Thx
堆栈跟踪似乎表明您没有在目标机器上安装 PostgreSQL 库。因此，要解决该问题，您可以下载软件的稳定版本 here 并确保在安装过程中检查了开发库。这将要求您在安装后关闭并重新打开所有活动的 cmd 会话。
之后，重新运行 bundle install --force（如果您使用的是早于 2.1 的捆绑器）或 bundle install --redownload（如果您使用的是 Bundler 2.1 或更高版本）Rails 项目，应该能够正确编译和运行。
如果它已安装但无法使用上述选项，请通过执行 gem install pg -f 重新安装 gem 或通过 gem install pg --pre 看看他们能否解决您的问题。

也许smb有同样的错误？ 非常感谢您的回答 Thx
堆栈跟踪似乎表明您没有在目标机器上安装 PostgreSQL 库。因此，要解决该问题，您可以下载软件的稳定版本 here 并确保在安装过程中检查了开发库。这将要求您在安装后关闭并重新打开所有活动的 cmd 会话。
之后，重新运行 bundle install --force（如果您使用的是早于 2.1 的捆绑器）或 bundle install --redownload（如果您使用的是 Bundler 2.1 或更高版本）Rails 项目，应该能够正确编译和运行。
如果它已安装但无法使用上述选项，请通过执行 gem install pg -f 重新安装 gem 或通过 gem install pg --pre 看看他们能否解决您的问题。
