布朗尼本地测试与Ganache失败

遵循Bootcamp Day2 Video中有关与布朗尼测试坚固合同的步骤，我在本地测试Chainlink-Mix脚本时偶然发现了错误。

Here are the steps are taken to introduce the error:

execute brownie compile
execute genache-cli in separate terminal
execute brownie run scripts/price_feed_scripts/01_deploy_price_consumer_v3.py
brownie run scripts/price_feed_scripts/02_read_price_feed.py

ganache is selected as the default network and the server在IP/端口127.0.0.1:8545上聆听。

brownie run scripts/price_feed_scripts/02_read_price_feed.py
Brownie v1.18.1 - Python development framework for Ethereum

ChainlinkMixProject is the active project.

Ganache在Brownie-Config.yaml中设置为默认网络

原文

Following the steps taken in the bootcamp day2 video on testing solidity contracts with brownie, I stumbled upon an error when testing the chainlink-mix scripts locally.

Here are the steps are taken to introduce the error:

execute brownie compile
execute genache-cli in separate terminal
execute brownie run scripts/price_feed_scripts/01_deploy_price_consumer_v3.py
brownie run scripts/price_feed_scripts/02_read_price_feed.py

ganache is selected as the default network and the server is listening on the ip/port 127.0.0.1:8545.

brownie run scripts/price_feed_scripts/02_read_price_feed.py
Brownie v1.18.1 - Python development framework for Ethereum

ChainlinkMixProject is the active project.

ganache is set as default network in the brownie-config.yaml

默认情况下，布朗尼不会将已部署的合同的位置保存到本地运行链中，因为它们经常被删除，并且会占用大量空间，因此您必须告诉布朗尼以记住部署到Ganache的东西。

在您的Brownie-config.yaml添加

dev_deployment_artifacts: true

和重新运行脚本中

Brownie doesn't save the location of deployed contracts to a local running chain by default since they get deleted so often and would take up a ton of space, so you have to tell brownie to remember stuff deployed to ganache.

In your brownie-config.yaml add
