有人可以帮我解决这个问题。

Answer 1

您有多个版本的activesupport。你应该删除其中一个：

$ gem list | grep activesupport

Activesupport (5.1.1, 5.0.4, 5.0.3, 5.0.2, 5.0.0.1, 4.2.6, 4.2.5, 4.2.4, 4.2.1, 4.1.6)

然后

$ gem uninstall activesupport -v 5.1.1

Successfully uninstalled activesupport-5.1.1

在您的情况下，我猜是activesupport-5.0.6

在创建应用程序时，该命令似乎正在尝试加载多个rails依赖项。

您可以通过

解决此问题

$ gem update rails

或者

$ gem update --system

Answer 3

你可以使用

ssh

然后

'Number in Scope (Aus Basisdata!D9 in Column I)
Scope.Cells(NextRow, Column).FormulaLocal = "='" & DateiPath & "]Basisdata'!$D$9"
        Column = Column + 1
