問(wèn)題：超時(shí)時(shí)間設(shè)置過(guò)短锨络。 src/fabric/e2eUtils.js里調(diào)整超時(shí)時(shí)間 -

https://github.com/hyperledger/caliper/pull/162
具體：在安裝初始化之前chaincodes的deployed為false:
"chaincodes": [{"id": "simple11", "path": "contract/fabric/simple/go", "language":"golang", "version": "v2", "channel": "mychannel","deployed": false}],
安裝成功后再執(zhí)行的時(shí)候 chaincodes的deployed為true
