Question

步骤“git clone ...”，“startFabric.sh”和“npm.install”完成且没有错误。 “node query.js”结果为：

    Set wallet path, and associate user  PeerAdmin  with application
    error: [Client.js]: Failed to load user "PeerAdmin" from local key value store. Error: TypeError: this is not a typed array.
      at Function.from (native)
      at importKey (/home/peter/fabric-samples/fabcar/node_modules/fabric-client/lib/impl/CryptoSuite_ECDSA_AES.js:180:26)
      at fromString (/home/peter/fabric-samples/fabcar/node_modules/fabric-client/lib/User.js:228:28)
      at /home/peter/fabric-samples/fabcar/node_modules/fabric-client/lib/Client.js:968:22
    error: [Client.js]: Failed to load an instance of requested user "PeerAdmin" from the state store on this Client instance. Error: TypeError: this is not a typed array.

      at /home/peter/fabric-samples/fabcar/node_modules/fabric-client/lib/Client.js:968:22
   Caught Error [TypeError: this is not a typed array.]

注意：在git clone步骤之后，如文档中所述，fabric-samples / fabcar中没有“chaincode”，但在fabric-samples中有一个chaincode / fabcar。这似乎不会导致问题。注意：“构建您的第一个网络”中的所有步骤都没有问题。

Hyperledger Fabric 1.0已经针对Node.js版本＆gt; = 6.9和＆lt; 7.x版本如果您收到类似的错误，建议更新Node.js的版本（或使用版本管理器，如nvm）并重试。如果您已使用旧版本的Node运行var object = [{"id":1,"name":"a","childNodes":[{"id":11,"name":"aa","childNodes":[{"id":111,"name":"aaaa","childNodes":[]}]}]},{"id":2,"name":"a","childNodes":[{"id":22,"name":"aa","childNodes":[{"id":123,"name":"aaaa","childNodes":[]}]}]}] function findById(data, id) { for(var i in data) { var result; if(data.id == id) return data if(typeof data[i] == 'object' && (result = findById(data[i], id))) return result } } console.log(findById(object, 111)) console.log(findById(object, 22))，则应删除node_modules树并重新运行npm install以确保安装正确的依赖项。
