这与 youtube 上的 Patrick Collins 的“Solidity、Blockchain 和智能合约课程——从初学者到专家 Python 教程”有关。

具体来说，在 Infura 的 Rinkeby 测试网上运行我的程序时出现以下错误。

HTTPError: 401 Client Error: Unauthorized for url: https://rinkeby.infura.io/v3/3d6c16...

我按照一些人的建议进行了以下检查：

检查私钥。这正是我 Metamask 钱包里的东西。

我的 .env 如下所示：

export PRIVATE_KEY=0xf77f98d99d11d5d70aa230770e478aa68b4d0fbf058def08d56909373f46b4c5
export WEB3_INFURA_PROJECT_ID=c2cdf41913e344bc94720dc8244950eb

brownie-config.yaml 看起来像这样：

dotenv: .env
wallets:
  from_key: ${PRIVATE_KEY}

我尝试在 Infura.io 上打开一个新项目并向 .env 添加一个新项目 ID，但没有帮助。

该程序在 ganache-cli（使用命令：）上运行良好，brownie run scripts/deploy.py但在 Rinkeby 测试网（命令：）上运行良好brownie run scripts/deploy.py --network rinkeby。

该程序昨天按预期运行，但今天没有。互联网连接良好。完整的错误信息如下：

我想我解决了这个问题（虽然我不了解它的机制）。

我创建了一个新的 Infura 项目将新的项目 ID 复制到 .env 文件上的适当位置我关闭了终端并在brownie run scripts/deploy.py --network rinkeby新终端上运行了命令。这太尴尬了……我花了 2 天时间才弄清楚:(

这是一个配置错误：

  • 确保您验证了您的 infura 帐户，以便您可以使用 api 密钥。

  • 确保您使用了准确的 api 密钥。

  • 确保在运行命令之前保存了所有文件

  • 确保 metamask 连接到 rinkeby 并测试 eth
