`anchor test` error: Failed to run test: yarn run ts-mocha -p ./tsconfig.json -t 1000000 tests/**/*.ts: No such file or directory (os error 2)

Question

我刚刚用 anchor init 初始化了一个 solana dapp。然后我用 anchor build 构建成功。我也尝试测试 anchor test 命令，但它失败了，我还没有添加任何代码。这仍然是未修改的初始化代码，这是错误消息：

Failed to run test: yarn run ts-mocha -p ./tsconfig.json -t 1000000 tests/**/*.ts: No such file or directory (os error 2)

它说 tests 目录中没有文件，但是有 mydapp.ts 这个代码

import * as anchor from "@project-serum/anchor";
import { Program } from "@project-serum/anchor";
import { Mydapp } from "../target/types/mycalculatordapp";

describe("mydapp", () => {
  // Configure the client to use the local cluster.
  anchor.setProvider(anchor.Provider.env());

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

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

Answer 1

我不得不全局安装 yarn，因为我的系统上没有它

 sudo  npm i -g yarn

然后我得到 ts-mocha command not found 即使它在 package.json 上。所以我运行 npm install 安装所有依赖项。然后我得到 ts node 错误

  sudo npm i -g ts-node

终于成功了
