Solana Anchor Lang：anchor init 使用 TypeError 创建项目：无法读取未定义的属性（读取“方法”）

Question

对可能导致其停止工作的原因感到困惑，我安装了 solana 和 anchor 并能够测试项目。 anchor --version anchor-cli 0.26.0

nvm use 16.16.0
Now using node v16.16.0 (npm v8.11.0)

anchor init hello-world
yarn install v1.22.19

Initialized empty Git repository in /home/user/Code/anchor-second-test/hello-world/.git/
hello-world initialized

cd hello-world && anchor build工程。 不做任何改变，我运行anchor run test

1) hello-world
       Is initialized!:
     TypeError: Cannot read properties of undefined (reading 'methods')

这是生成的 hello-world.ts 测试文件：

import { Program } from "@project-serum/anchor";
import { HelloWorld } from "../target/types/hello_world";

describe("hello-world", () => {
  // Configure the client to use the local cluster.
  anchor.setProvider(anchor.AnchorProvider.env());

  const program = anchor.workspace.HelloWorld as Program<HelloWorld>;

  it("Is initialized!", async () => {
    // Add your test here.
    const tx = await program.methods.initialize().rpc();
    console.log("Your transaction signature", tx);
  });
});

我尝试使用 node lts 16.16.0 而不是最新的 lts，从一个干净的目录开始，检查是否安装了 typescript，在运行 anchor build 命令之前运行 yarn install。 我检查了 solana 密钥对和 json 文件是否在正确的文件夹中生成。

Go 到这个../target/types/hello_world目录并确保它像这样导出

export type HelloWorld = {}

因为你有这个import

import { HelloWorld } from "../target/types/hello_world";

另外，您没有显示anchor导入。 它应该是

import * as anchor from "@project-serum/anchor";
