有一个错误，我无法转述。

Question

我正在使用Uniswap来交换我工作得很好的令牌，但是现在它抛出了一个错误，但是我不知道为什么。我也安装了npm @uniswap/v3-periphery，但它不能为我工作。

这里是错误：

​

./node_modules/@uniswap/v3-sdk/dist/v3-sdk.esm.js:7:0
Module not found: Can't resolve '@uniswap/v3-periphery/artifacts/contracts/interfaces/IMulticall.sol/IMulticall.json'

Import trace for requested module:
./node_modules/@uniswap/smart-order-router/build/module/providers/on-chain-quote-provider.js

./node_modules/@uniswap/smart-order-router/build/module/index.js
./components/app/Swapping.jsx
./pages/swap/index.tsx

Answer 1

在卡住@uniswap/v3-periphery@1.4.1 3到4天后，如果找到了，通过安装一个特定版本的就可以解决这个问题。

​

npm i @uniswap/v3-periphery@1.4.1

在我按照你的指示跑完后，我就有这个问题了？你能解决同样的问题吗？
