部署时 R 无法找到包 RODBC 的存储库

Question

当我部署到 shinyapps.io 时，出现错误：

Unable to find repository URL for package RODBC

因此，当我通过 URL 打开图表时，它没有显示任何内容，因为它无法连接到我拥有的连接并将数据加载到我创建的数据框中。

部署信息：

包安装正常，连我的数据库都通过它搜索了。

我将问题发布到 R (R Community Question) 社区后，我最终按照@nirgrahamuk 指导的步骤进行操作，错误不再出现！

所以我不得不将 R 版本更新到最新版本，它成功了！

在 R 中执行命令后，他问：

更新R版本后：

所以版本已经从R version 3.6.1 (2019-7-05)更新到R version 4.0.2 (2020-06-22)。

并且错误不再出现：
