我遇到了同样的问题，并且能够使用以前版本的 SSMS(SQL Server Management Studio)解决这个问题，而不是 SQL Server 版本。以前的 SSMS 版本可以在这里下载:

https://docs.microsoft.com/en-us/sql/ssms/release-notes-ssms?view=sql-server-ver15#1791

ATTOW，当前版本是18.5。它适用于 17.9.1 和 18.4 版。

这在 SQL Server 2017 和 2019 上都适用于我，这是 SSMS 的问题，而不是 SQL Server 版本的问题。

我还尝试了带有 SQL Dacpac 扩展 ( https://github.com/microsoft/azuredatastudio/tree/master/extensions/dacpac ) 的 Azure Data Studio，但它失败了，错误与最新的 SSMS 版本相同。有一个问题未解决:https://github.com/microsoft/azuredatastudio/issues/9522

或者，不安装 SSMS，而是安装 sqlpackage来自 https://docs.microsoft.com/en-us/sql/tools/release-notes-sqlpackage?view=sql-server-ver15#184-sqlpackage (版本 18.4)并手动运行命令。就像是:
sqlpackage.exe /a:Import /df:"import.log" /sf:"mybacpac-2020-04-26.bacpac" /tcs:"Server=.;Database=mybacpac;Integrated Security=true"
