如何使用 eth-brownie python 執行 Chainlink 項目

我已經使用命令安裝了 eth-brownie

pip install eth-brownie

布朗尼安裝後。我已經將現有的布朗尼項目烘焙到一個新目錄中。

mkdir MyChainlinkProject
cd MyChainlinkProject/
brownie bake chainlink-mix
cd chainlink-mix

然後導出 infura.io 項目 id 和 kovan 網路私鑰

export WEB3_INFURA_PROJECT_ID='d1f95888fba84a42adasaa37803d4b5118ee'
export PRIVATE_KEY='0x5FE9bE1eC79dFE85b2748F6fEdasd60f811a8Ee997D9'

最後嘗試了這個命令

brownie run scripts/price_feed_scripts/deploy_price_consumer_v3.py --network kovan

返回錯誤

所以任何人都有想法。謝謝

當我嘗試執行部署腳本時，我在 Brownie 中遇到了同樣的問題。

在主目錄之外執行您的項目。在我的情況下，我的主目錄 C:/Users/nyamgavaa.g 路徑 inporter 要求沒有帶有“.”的主目錄。這樣解決我的問題
