【问题描述】：

我是区块链、智能合约和近乎协议的新手。我正在尝试向 https://near.academy/ 学习。 testnet 上有一个示例合约：museum.testnet。

我使用的是 windows 并安装了 wsl2。

我可以登录 near login 命令。但在那之后，当我调用near view museum.testnet getmemecount 命令时，它给了我下面的错误。谁能帮我解决这个问题？

View call: museum.testnet.getmemecount()
An error occured

【参考方案1】：

方法名称是get_meme_count，而不是getmemecount。见博物馆源代码here。

$ near view museum.testnet get_meme_count
View call: museum.testnet.get_meme_count()
67

附近学院的某些部分是否将其称为getmemecount？

【讨论】：

非常感谢。 1天后我在交易中意识到了这一点。是的，学院文件说：，4。现在合同名称是“museum.testnet”，方法称为getmemecount。所以输入：near view museum.testnet getmemecount。这将返回您在博物馆中注册的模因数量。 5. 恭喜。你刚刚在 NEAR 上调用了一个合约。 near.academy/near101/chapter-4
