为什么在 SSH 工作时收到 SCP 的权限被拒绝（公钥）错误

Question

我正在尝试使用 SCP 将文件从我的本地主机复制到我的 Amazon EC2 实例并收到错误：

警告：身份文件 blocks_key.pem 不可访问：没有这样的文件或目录。权限被拒绝（公钥）。失去了连接

提示这个错误的命令是：

scp -i ~/Desktop/Blocks/blocks_key.pem ~/Desktop/Blocks/code/www/uploadtest.html ubuntu@ip.address:/var/www

我能够使用相同的 -i ~/Desktop/Blocks/blocks_key.pem 进行 SSH，所以我不清楚为什么这不能正常工作。任何见解将不胜感激！

也许你发现了一个错误？

做同样事情的另一种方式（想知道这对你有用吗？）：

scp -oIdentityFile=/Users/emmie/Desktop/Blocks/blocks_key.pem ~/Desktop/Blocks/code/www/uploadtest.html ubuntu@ip.address:/var/www

此外，如果您发布以下输出，它可能会有所帮助（只是好奇）：

stat /Users/emmie/Desktop/Blocks/blocks_key.pem
