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)

Solana CPI (runtime) invoke fails when creating a new account by system_instruction::create_account (on-chain program with anchor framework)

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

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。

我意识到了这个问题:

  1. 我没有将 system_program 传递给指令。
pub system_program: Program<'info, System>
  1. 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] ]]
        )?;
