Orbitdb是否有额外的依赖关系？

Question

对于使用IPFS的Orbitdb，可能有一些额外的依赖项，这些依赖项在任何地方都没有特别提到。我尝试从文档中创建一个简单的键值db：

orbit.js

const IPFS = require("ipfs");
const OrbitDB = require("orbit-db");

    const ipfsOptions = {
      EXPERIMENTAL: {
        pubsub: true
      }
    };

    const ipfs = await IPFS.create(ipfsOptions);
    const orbitdb = await OrbitDB.createInstance(ipfs);
    const db = await orbitdb.create("test", "keyvalue", {
      overwrite: true,
      replicate: true,
      accessController: {
        type: "ipfs",
        admin: ["*"],
        write: ["*"]
      }
    });
    await db.set("hello", "world");
    console.log(db.all);

我的package.json中有以下依赖项

"dependencies": {
    "ipfs": "^0.46.0",
    "orbit-db": "^0.24.1"
}

它抛出了以下错误：

Trace: Error: Could not append entry, key "..." is not allowed to write to the log

我试着解决它，但似乎什么都不起作用。现在，有趣的部分来了。因此，我目前正在开发使用Orbitdb的代码的前端部分。出于好奇，我将orbit.js文件复制粘贴到了包含前端代码的根文件夹中。在那里运行相同的文件，运行得很好，成功地创建了数据库！以下是前端代码(在Angular中)的package.json中的所有依赖项和开发依赖项：

我知道这些依赖关系中的大多数甚至都与Orbitdb无关，我绝对可以将它们缩小到特定的依赖关系，但有人能解释一下为什么它在这里工作吗？我对Orbitdb的使用完全陌生。

OrbitDB已经正确处理了它的依赖关系

你的代码应该可以工作，你甚至可以简化它

const start = async () => {
  const ipfs = await IPFS.create();
  const orbitdb = await OrbitDB.createInstance(ipfs);
  const db = await orbitdb.create("test", "keyvalue", {
    overwrite: true,
    replicate: true,
    accessController: {
      write: ["*"],
    },
  });
  await db.set("hello", "world");
  console.log(db.all);
  db.close();
  ipfs.stop();
};

start();
