system_instruction::create_account 创建新账户时 Solana CPI（运行时）调用失败（带锚框架的链上程序）

Question

我正在尝试创建一个让用户铸造 SPL 令牌的简单程序。该程序由 Anchor 引导。不幸的是，它在通过 CPI 创建 PDA 帐户的第一步失败了。详情请见下方：

----处理器-----

我试图简化链上程序的处理器，使用 Solana 系统程序创建一个简单的 PDA 帐户。处理器只有一个CPI。

----说明-----

我还尝试通过只输入 4 个帐户来简化指令（请参见屏幕截图或随附的我的代码）：在打字稿测试代码中，它也很简单。我只是导出一个 PDA，然后将这个 PDA 和其余 3 个帐户传递到指令中。（两个约束1.分配签名者2.为PDA帐户设置mut）

-----错误-----

但我仍然得到错误

    1) is minted


  2 passing (2s)
  1 failing

  1) anchor_programs
       is minted:

似乎我没有将正确的帐户传递到调用主体中，但我花了一整天的时间检查但仍然不确定是否还有其他丢失的帐户（或 AccountInfo）。如果有人能给我提示，我将不胜感激。您可以在屏幕截图格式中看到我的代码摘要。

Answer 1

我意识到了这个问题：

我没有将 system_program 传递给指令。

pub system_program: Program<'info, System>

需要用invoke_signed也让pda签

invoke_signed(                                                            
            &create_acc_ix,                                             
            &[                          
                self.minter.clone(),
                self.mint_pda_acc.clone(),
            ],
            &[&[ &mint_seed.as_ref(), &[*bump_seed] ]]
        )?;
