我正在玩 PhotoEditor SDK，遵循他们的https://docs.photoeditorsdk.com/quickstarts/rails.

我能够使用 SQLite 启动第一个测试应用程序以熟悉 SDK，并且一切正常。

所以，我决定更认真地尝试一下，一切从头开始，这次是用 Postgresql。

每次我尝试使用 迁移我的数据库时rails db:migrate，都会收到以下错误：

rails aborted!
Invalid format of target version: `VERSION=3.6.5`
/Users/user/code/palette/bin/rails:9:in `<top (required)>'

(See full trace by running task with --trace)

这是完整的跟踪：

看起来这与export VERSION=3.6.5之前执行的命令有关。

知道发生了什么以及如何解决这个问题吗？

你是对的，这是因为VERSION你设置了克隆 sdk 的环境变量。它是从这里提出来的：

      def check_target_version
        if target_version && !(Migration::MigrationFilenameRegexp.match?(ENV["VERSION"]) || /\A\d+\z/.match?(ENV["VERSION"]))
          raise "Invalid format of target version: `VERSION=#{ENV['VERSION']}`"
        end
      end

在查看快速入门指南后，我认为您需要 VERSION 变量来获取 sdk，之后就不需要了。

因此，在这种情况下，您可以取消设置 VERSION 环境变量并且应该修复它，您可以通过运行unset VERSION. 让我知道它是否有帮助。
