安全帽配置問題的錯誤部署

我的配置文件中有錯誤：錯誤 HH8：您的配置文件中有一個或多個錯誤：

 * Invalid value undefined for HardhatConfig.networks.rinkeby.url - Expected a value of type string.
 * Invalid value {} for HardhatConfig.networks.rinkeby - Expected a value of type HttpNetworkHDAccountsConfig.
 * Invalid value undefined for HardhatConfig.networks.ropsten.url - Expected a value of type string.

我實際上使用上面的配置文件將智能合約部署到不同的網路幾次。知道我不知道發生了什麼變化。有任何想法嗎？

您使用的似乎是一個env變數，因此要麼添加前綴process.env（如果這些變數在 .env 中定義），要麼硬編碼“HTTP”地址

林克比的一個例子：

rinkeby: {
     url: process.env.RINKEBY_RPC_URL || "http://your-rinkeby-provider",
     accounts: {
       mnemonic: MNEMONIC,
     },
   },

你的 .env 應該是這樣的：

  ETHERSCAN_API_KEY=ABC123ABC123ABC123ABC123ABC123ABC1
  RINKEBY_RPC_URL=https://eth-rinkeby.alchemyapi.io/
  PRIVATE_KEY=0xabc123abc123abc123abc123abc123abc123abc123abc...

process.env要訪問這些變數，您需要process.env.RINKEBY_RPC_URL在您的hardhat-config

找到了我的問題的根源。我使用 .gitignore 文件來自 github 上的 pre-build .gitignore 文件夾-節點一（可以在這裡看到）可能忽略了我需要的東西（不知道具體是什麼）。
