背景
我目前正在研究Hyperledger Fabric。因此，我在本地计算机上安装了先决条件，并尝试遵循this tutorial关于fabcar。
问题
一切顺利，直到我运行了node query.js，这会返回此错误：
Store path:/home/me/fabric-samples/fabcar/hfc-key-store
Successfully loaded user1 from persistence
error: [client-utils.js]: sendPeersProposal - Promise is rejected: Error: 14 UNAVAILABLE: Connect Failed

at /home/me/fabric-samples/fabcar/node_modules/fabric-client/node_modules/grpc/src/client.js:583:15

解决方案尝试
我已经尝试遵循类似问题的答案，尤其是这个问题：Hyperledger fabcar sample fabric showing connect failed ERROR。
所以我运行了ifconfig（在删除所有容器之后：]]
docker0: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500 inet 172.17.0.1 netmask 255.255.0.0 broadcast 172.17.255.255 ether 02:42:b3:67:1a:ec txqueuelen 0 (Ethernet) RX packets 0 bytes 0 (0.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 0 bytes 0 (0.0 B) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 enp1s0: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500 ether c8:d3:ff:25:43:ff txqueuelen 1000 (Ethernet) RX packets 0 bytes 0 (0.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 0 bytes 0 (0.0 B) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536 inet 127.0.0.1 netmask 255.0.0.0 inet6 ::1 prefixlen 128 scopeid 0x10<host> loop txqueuelen 1000 (Local Loopback) RX packets 282 bytes 24402 (24.4 KB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 282 bytes 24402 (24.4 KB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 wlp2s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 192.168.1.30 netmask 255.255.255.0 broadcast 192.168.1.255 inet6 fe80::99eb:462:7866:d63 prefixlen 64 scopeid 0x20<link> ether 30:e3:7a:2c:4d:ae txqueuelen 1000 (Ethernet) RX packets 419 bytes 86802 (86.8 KB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 391 bytes 64650 (64.6 KB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0然后我将
localhost中的192.168.1.30替换为query.js：
var peer = fabric_client.newPeer('grpc://192.168.1.30:7051');和
invoke.js：
var peer = fabric_client.newPeer('grpc://192.168.1.30:7051'); var order = fabric_client.newOrderer('grpc://192.168.1.30:7050') event_hub.setPeerAddr('grpc://192.168.1.30:7053');我从头开始做了一切，但是在查询汽车时却产生了相同的错误。
我也尝试过the solution here，但是我的bashrc中没有代理行，因此无可奉告。
感谢您的任何帮助。

由于我不知道该怎么办，因此我删除了所有内容并再次从头开始，这次使用的是最新的织物样品版本（我以前没有意识到我使用的是旧版本）。之后，它运行顺利，即未遇到任何错误。
