enrolladmin.js的Hyperledger Fabric Fabcar错误

Question

我已经启动了Fabric脚本，然后运行了enrolladmin.js文件。

node enrolladmin.js

但出现以下错误。 怎么解决呢？

node enrollAdmin.js
fs.js:904
return binding.readdir(pathModule._makeLong(path), options.encoding);
             ^

Error: ENOENT: no such file or directory, scandir '/Users/jaspalsingh/fabric-samples/fabcar/node_modules/grpc/src/node/extension_binary'

Answer 1

我有同样的问题。 只需通过以下步骤解决它：

1. 创建目录：<FABCAR_DIR> / node_modules / grpc / src / node / extension_binary /
2. 在<FABCAR_DIR>中执行“ npm install”
3. 在<FABCAR_DIR>中执行“ npm rebuild”

第2步或第3步-其中一个应解决问题-按相同顺序尝试。

在执行完第2步或第3步之后-您应该看到一个文件。 <FABCAR_DIR> /node_modules/grpc/src/node/extension_binary/node-v46-linux-x64-glibc/grpc_node.node

在那之后，注册管理员应该会像这样成功：

sprint @ fabcar>node enrollAdmin.js
 Store path:/home/ravir/hl/fabric-samples/fabcar/hfc-key-store
Successfully enrolled admin user "admin"
Assigned the admin user to the fabric client ::{"name":"admin","mspid":"Org1MSP","roles":null,"affiliation":"","enrollmentSecret":"","enrollment":{"signingIdentity":"42d8536072cf7e47358c137b254d78d8e853934caee70d03dbec06a22f482ad9","identity":{"certificate":"-----BEGIN CERTIFICATE-----\}

如果您仔细观察，则会显示startFabric.sh的输出

“

Start by installing required packages run 'npm install'
Then run 'node enrollAdmin.js', then 'node registerUser'
