Unknown type: ICErc20 when been compiled

[franklili3]

I have installed hardhat and solidity, when I run yarn compile, there is error,

Creating Typechain artifacts in directory typechain for target ethers-v5 Error: Unknown type: ICErc20 at Object.parseEvmType (/Users/linda/myprojects/set-protocol-v2/node_modules/typechain/src/parser/parseEvmType.ts:96:9) at parseRawAbiParameterType (/Users/linda/myprojects/set-protocol-v2/node_modules/typechain/src/parser/abiParser.ts:284:10) at parseRawAbiParameter (/Users/linda/myprojects/set-protocol-v2/node_modules/typechain/src/parser/abiParser.ts:273:11) at Array.map () at parseFunctionDeclaration (/Users/linda/myprojects/set-protocol-v2/node_modules/typechain/src/parser/abiParser.ts:263:29) at /Users/linda/myprojects/set-protocol-v2/node_modules/typechain/src/parser/abiParser.ts:157:22 at Array.forEach () at Object.parse (/Users/linda/myprojects/set-protocol-v2/node_modules/typechain/src/parser/abiParser.ts:138:7) at Ethers.transformAbiOrFullJsonFile (/Users/linda/myprojects/set-protocol-v2/node_modules/@typechain/ethers-v5/src/index.ts:86:22) at Ethers.transformFile (/Users/linda/myprojects/set-protocol-v2/node_modules/@typechain/ethers-v5/src/index.ts:56:17) error Command failed with exit code 1.

How can I do? MacOS Mojave 10.14.6 solidity@6 Hardhat 2.2.1

I got the reason, because I have not run yarn install. But when I run 'yarn install', there was error:
