Flutter无法创建keystore：keytool提示文件路径找不到求助

我按指引操作创建Keystore，操作流程如下，但最终出现报错，且找不到生成的keystore文件，想问下是不是创建没成功？

报错信息 #

解答 #

• 是的，你的Keystore没有创建成功。
• 报错核心是系统无法解析%userprofile%环境变量，导致keytool找不到要写入的文件路径，最终生成失败。
• 修复方案：
  • 直接使用绝对路径，比如把命令里的路径换成C:\Users\你的实际用户名\upload-keystore.jks
  • 先通过cd %userprofile%命令切换到用户目录，再执行keytool命令，此时只需要指定文件名upload-keystore.jks即可
