前言
這是一個(gè)罕見(jiàn)問(wèn)題，發(fā)生在私有鏈ETH環(huán)境下蔼水，當(dāng)執(zhí)行truffle migrate --network development
Error: *** Deployment Failed ***
"Migrations" exceeded the block limit (with a gas value you set).
* Block limit: 0x31d836
* Gas sent: 6721975
* Try:
+ Sending less gas.
+ Setting a higher network block limit if you are on a
private network or test client (like ganache).
問(wèn)題的原因是block limit小于gas花費(fèi)。

當(dāng)時(shí)，我才挖出來(lái)583個(gè)，那個(gè)時(shí)候 gasLimit: 5548767箩祥，但是部署合約消耗，6721975肆氓。于是袍祖，我就各種查資料，然后谢揪，又再一次執(zhí)行了部署程序蕉陋，神奇的通過(guò)了。
