Solana metaplex-program-library 线程“主”在“代码不可解析：错误（“必须为 init 提供空间”）时出现恐慌

Question

I am trying to compile and set up a local Solana node with Metaplex installed for local development. Right now when compiling with anchor build - I've been getting the following error:

To deploy this program:
  $ solana program deploy /sol/metaplex/program-library/target/deploy/mpl_fixed_price_sale.so
The program address will default to this keypair (override with --program-id):
  /sol/metaplex/program-library/target/deploy/mpl_fixed_price_sale-keypair.json

It appears to originate in: fixed-price-sale/program/src/lib.rs inside pub struct Buy the following lines:

pub struct Buy<'info> {
...
  #[account(init_if_needed, seeds=[HISTORY_PREFIX.as_bytes(), user_wallet.key().as_ref(), market.key().as_ref()], bump, payer=user_wallet)]
  trade_history: Box<Account<'info, TradeHistory>>,
...
}

When I comment these two lines out and comment out an entire fixed-price-sale/program/src/processor/buy.rs - it compiles with some warnings, but clearly there is now functionality missing. What is missing here?

Answer 1

Looks like a bug. The space parameter is missing.

Need to change:

...
#[account(
  init_if_needed, 
  seeds=[
    HISTORY_PREFIX.as_bytes(), 
    user_wallet.key().as_ref(), 
    market.key().as_ref()
  ], 
  bump, 
  payer=user_wallet
)]
trade_history: Box<Account<'info, TradeHistory>>,
...

to this:

...
#[account(
  init_if_needed, 
  space=TradeHistory::LEN, // <-------------- Added this line
  seeds=[
    HISTORY_PREFIX.as_bytes(), 
    user_wallet.key().as_ref(), 
    market.key().as_ref()
  ], 
  bump,
  payer=user_wallet
)]
trade_history: Box<Account<'info, TradeHistory>>,
...
