由于某种原因，我的mocha测试无法找到我的IDL。我得到以下错误：

它被正确地生成并保存在我的目标IDL文件夹中(../solana anchor reactjs payment/target/IDL/payment.json(，下面是IDL文件的内容：
{

调用这个IDL的测试是下面的测试(../solana anchor reactjs payment/tests/payment test.ts(：
import * as anchor from '@project-serum/anchor';
import { Program } from '@project-serum/anchor';
import {Payment} from "../target/types/payment";
import * as assert from "assert";
describe('send payment message', () => {
// Configure the client to use the local cluster.
anchor.setProvider(anchor.Provider.env());
const program = anchor.workspace.Payment as Program<Payment>;
it('can send a new payment', async () => {
// Call the "SendTweet" instruction.
const payment = anchor.web3.Keypair.generate();
await program.rpc.sendPayment('veganism', {
accounts: {
paymentState: payment.publicKey,
sender: program.provider.wallet.publicKey,
systemProgram: anchor.web3.SystemProgram.programId,
},
signers: [payment],
});
//Fetch the account details of the payment sender
const senderAccount = await program.account.paymentState
.fetch(payment.publicKey);
assert.ok(senderAccount.timestamp);
assert.equal(senderAccount.sender.toBase58(), program.provider.wallet.publicKey.toBase58())
assert.ok(senderAccount.note, 'Starbucks Coffee');
assert.ok(senderAccount.amount, '8');
assert.fail(senderAccount.amount, 200);
});
});
测试可能无法访问IDL所在的文件夹。所以我甚至把它物理复制到测试的同一个文件夹中，但仍然没有成功。如有任何帮助，我们将不胜感激，并提前表示感谢。
Update这并不理想，但您可以通过解析idl-json文件，然后将其作为程序中的对象传入来解决这个问题。您可以添加以下行来设置程序：
// Read the generated IDL.
const idl = JSON.parse(
require("fs").readFileSync("./target/idl/payment.json", "utf8")
);
//Address of the deployed program
const programId = new anchor.web3.PublicKey("8BBGEacFKQ1dYDPF39HstjAC2195iV1ta9scv1WxtJfT");
//Generate the program client from IDL
const program = new anchor.Program(idl, programId);
我也遇到了类似的问题，您需要仔细检查并确保正确命名和引用了所有内容。对我来说，这个问题出现在程序的Cargo文件中，特别是我给库命名错误，它需要与程序同名，而且它的大写错误
[package]
name = "program-name"
version = "0.1.0"
description = "Created with Anchor"
edition = "2018"
[lib]
crate-type = ["cdylib", "lib"]
name = "program_name". //Here was the issue needed to have the same name as the program itself
[features]
no-entrypoint = []
no-idl = []
no-log-ix-name = []
cpi = ["no-entrypoint"]
default = []
[dependencies]
anchor-lang = "0.21.0"
anchor-spl = "0.21.0"
下面是一个带有程序的lib.rs示例
#[program]
pub mod program_name {
...
}
我也遇到了类似的问题，在运行测试时，它起了作用，但它给了我错误：在程序的IDL中找不到元数据属性，在这种情况下，它不是暴露的相同错误，它是Cargo.toml中的Anchor版本，我更新了，一切正常
如果您正在使用Anchor，请检查您的Anchor.toml文件，可能存在程序名称拼写错误。
