查询.js在Hyperledger fabric fabcar示例中崩溃

Question

在尝试运行fabcar的步骤中，超级费用教程的query.js示例崩溃了。

我删除了所有与hyperledger相关的docker镜像（使用docker rmi），因此在运行startFabric.sh时会自动下载所有必需的内容。启动时的输出看起来略微变暗＆＃34;阴云密布＆＃34;但不是很可疑（我跳过了关于下载图像的冗长输出）：

# wait for Hyperledger Fabric to start
# incase of errors when running later commands, issue export FABRIC_START_TIMEOUT=<larger number>
export FABRIC_START_TIMEOUT=10
#echo ${FABRIC_START_TIMEOUT}
sleep ${FABRIC_START_TIMEOUT}

# Create the channel
docker exec -e "CORE_PEER_LOCALMSPID=Org1MSP" -e "CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/msp/users/Admin@org1.example.com/msp" peer0.org1.example.com peer channel create -o orderer.example.com:7050 -c mychannel -f /etc/hyperledger/configtx/channel.tx
flag provided but not defined: -e
See 'docker exec --help'.

要求的下一步是

npm install

它也提供了大部分正常的输出，只有一个警告：

npm WARN fabcar@1.0.0 No repository field.

我已验证图片正在运行（还显示用户有权使用泊坞窗，而用户则不 root）：

docker ps

当我最终尝试运行时

node query.js

我发现以下错误：

Create a client and set the wallet location
Set wallet path, and associate user  PeerAdmin  with application
Check user is enrolled, and set a query URL in the network
Make query

我的操作系统：

uname -a
Linux uhost 4.4.0-92-generic #115-Ubuntu SMP Thu Aug 10 09:04:33 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

我检查了this，但我的node.js版本是正确的：

node --version
v6.11.2

npm -- version
{ fabcar: '1.0.0',
  npm: '3.10.10',
  ares: '1.10.1-DEV',
  http_parser: '2.7.0',
  icu: '56.1',
  modules: '48',
  node: '6.11.2',
  openssl: '1.0.2l',
  uv: '1.11.0',
  v8: '5.1.281.103',
  zlib: '1.2.11' }

此外，错误消息完全不同。该机器正在使用端口8080和8443，但是当我厌倦了关闭使用它们的应用程序时，没有帮助。

那是因为您没有按照步骤进行操作..如它所说，在query.js之前，您应该先注册管理员并注册用户，然后它才能正常工作。并且不要关注“ npm WARN fabcar@1.0.0无存储库字段”，它很好用。请尝试以下操作：

$docker stop $(docker ps -a -q)
$docker ps -qa|xargs docker rm
$./startFabric.sh
$cd fabric-samples/fabcar/javascript
$node enrollAdmin.js
$npm install
$node registerUser.js
$node query.js
