Invalid Private Key, Not a valid string or uint8Array

报这种错误：一般在生成private key前面添加"0x"即可解决。我就是在私钥前面添加了"0x"解决了。

在学习web3时，使用助词生成的私钥，然后由私钥导出keystore就报错：

开始报错以为是自己没开梯子,但我用之前写的demo是能查询到eth账户余额，于是根据报错信息怀疑是生成的privatekey不对，我照着学习的视频检查了代码跟它一样没问题呀，然后我在生成的私钥前面添加了"0x"就可以了。

//获取钱包私钥
    const privateKey=wallet.getPrivateKey().toString("hex");    
const web3 = new Web3(
        Web3.givenProvider || 'wss://sepolia.infura.io/ws/v3/018c25a8b5ce4f23810c49f60478471f');
    const keystore = web3.eth.accounts.encrypt('0x'+privateKey,'111111');

搞定。
