Hyperledger burrow集成truffle

環境

os:centos7.6

1. 安裝nodejs和npm

安裝nvm

curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.11/install.sh | bash
export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"  # This loads nvm 
 nvm --version

使用nvm安裝node和npm

nvm install node
node --version
npm --version

安裝開發工具

sudo yum install gcc-c++ make

2. 安裝solc

參考：https://blog.csdn.net/kk3909/article/details/105381559

3. 安裝truffle

npm install truffle -g

報錯?

Error: EACCES: permission denied, open '/root/.config/truffle/config.json'
You don't have access to this file

再安裝一次

npm install truffle -g --unsafe-perm

4. 使用truffle部署智能合約

4.1 創建項目

mkdir MetaCoin
cd MetaCoin
truffle unbox metacoin

4.2 修改config

cat truffle-config.js
module.exports = {
  networks: {
    burrow: {
      host: "localhost",
      port: 26860,
      network_id: "*"
   }
  }
};

4.3 編譯

truffle  compile

4.4 測試

truffle  test

4.5 部署

 truffle  deploy --network burrow

報錯？

Error: Expected parameter 'from' not passed to function.

看起來是缺少from參數，修改一下truffle-config.js，from爲節點的創世地址。

module.exports = {
  networks: {
    burrow: {
      host: "localhost",
      port: 26860,
      from: "7E4F21487B2E2CB2F6DE9AEA1875BD1FC55114CE",
      network_id: "*"
   }
  }
};

還是出錯，通過web3.eth.accounts是查詢不到任何賬戶的，問題應該在這。

web3不支持ed25519類型的地址，我們重新生成賬戶，再測試。

./burrow spec -v1 -d1 |./burrow configure -s-  --curve-type secp256k1 >burrow.toml

這時通過web3.eth.accounts可以查詢到賬戶，再部署一遍
還是報錯？

經查詢根本沒有這個賬戶0xbdb18dda8da1bfc0123143674f86d8ca506c9ffa，從哪來？?

發現都是dry-run時報錯,最終解決方案:

 truffle  deploy --network burrow --skip-dry-run

可以部署、調用合約,但通過grpc 不能獲取合約metadata數據

結論

burrow暫時還不完全兼容truffle
