IPFSAccessController.save ERROR: Error: Deprecated, use .toString()

Question

我只是想启动应用程序套件 OrbitDB 的示例，它是：

import OrbitDB from "orbit-db";
import IPFS from "ipfs";

async function main () {
  // Create IPFS instance
  const ipfsOptions = { repo : './ipfs', }
  const ipfs = await IPFS.create(ipfsOptions)

  // Create OrbitDB instance
  const orbitdb = await OrbitDB.createInstance(ipfs)

  // Create database instance
  const db = await orbitdb.keyvalue('ipfs_db')
}

main()

你可以在这里找到它：https://github.com/dappkit/aviondb#using-nodejs

但问题是当我启动它时，出现了这些错误：

我真的不知道该怎么做，我尝试清除缓存，删除 node_modules 和 package-lock.json，然后执行 npm install，但没有任何改变，我遇到同样的错误，你有什么办法解决这个问题吗？

Answer 1

这个错误清楚地表明 IPFS 和 OrbitDB 之间不兼容。

OrbitDB v0.26.1 支持的js-ipfs最新版本是0.55.4。您应该将 package.json 中的 ipfs（或 ipfs-core）版本更改为 ^0.55.4。

注：The upcoming OrbitDB v0.27, will support the latest IPFS version.
