TypedError:无法在网络测试网上为帐户andrius.testnet签名事务，在InMemorySigner中找不到匹配的密钥对

Question

当我试图在近api-js库上调用我的create_account函数时：

        await creatorAccount.functionCall({
            contractId: process.env.NEAR_NETWORK_ID || "",
            methodName: "create_account",
            args: {
                new_account_id: newAccount,
                new_public_key: publicKey,
            },
            gas: new BN("300000000000000"),
            attachedDeposit: new BN("10000000000000000000"),
        });

最后我得到了一个例外：

i  functions: Beginning execution of "api"

我添加了一些日志，以确认签名者帐户确实存在于该路径上：

> {"severity":"INFO","message":"Signer account: /var/folders/f4/qjf99cc92k5gm4n45c98h5480000gn/T/andrius.testnet.json exists: true"}

我还没有完全弄清楚问题出在哪里，有人有什么想法吗？

Answer 1

我通过从内存中加载私钥字符串来解决这个问题：

const keyStore = new keyStores.InMemoryKeyStore();
const keyPair = KeyPair.fromString(PRIVATE_KEY);
