【中文标题】使用 API_URL 和私钥导入的 Hardhat 编译错误【英文标题】:Hardhat compile error with API_URL and Private Key import 【发布时间】:2021-11-30 04:03:18 【问题描述】:追随基本的NFT tutorial,我不得不说,我在编程方面有点菜鸟。我面临的问题是我的 hardhat.config.js 文件需要一个 API_KEY 和一个私钥,它应该从 process.env 文件中导入:
API_URL = "https://ethropsten.alchemyapi.io/v2/UkW3oySI7WxvFwDwopQHPOHajHaWFZFv"
PRIVATE_KEY = "8d33c2613cb63d0dc6305e57..."
hardhad 配置文件如下所示:
* @type import('hardhat/config').HardhatUserConfig
*/
require('dotenv').config();
require("@nomiclabs/hardhat-ethers");
const API_URL, PRIVATE_KEY = process.env;
module.exports =
solidity: "0.8.0",
defaultNetwork: "ropsten",
networks:
hardhat: ,
ropsten:
url: API_URL,
accounts: [`0x$PRIVATE_KEY`]
,
但是每当我尝试编译它并在我的 deploy.js 文件中运行它时,我都会收到一条错误消息,基本上告诉我,导入是不可能的,看起来像这样:
* Invalid value undefined for HardhatConfig.networks.ropsten.url - Expected a value of type string.
* Invalid value "accounts":["0xundefined"] for HardhatConfig.networks.ropsten - Expected a value of type HttpNetworkConfig.

我首先想到,我的 .env 文件不在正确的位置或语法不正确,但在尝试了我能想到的一切之后,我仍然收到相同的错误消息。任何帮助表示赞赏。
【问题讨论】:
【参考方案1】:我遇到了这个问题,因为我在环境变量前面添加了“导出”。 删除“导出”后,我就可以从安全帽配置中访问它们
【讨论】:
这没有提供问题的答案。一旦你有足够的reputation,你就可以comment on any post;相反,provide answers that don't require clarification from the asker。 - From Review【参考方案2】:我通过在hardhat.config.js
文件中使用它解决了同样的问题:
require('dotenv').config(path:__dirname+'/.env')
代替:
require('dotenv').config()
欲了解更多信息,您可以访问 dotenv file is not loading environment variables
