This is because Mythril uses Solidity to compile the program, to circumvent this issue we can use the following solc-json file: |

This is because Mythril uses Solidity to compile the program. Solidity does not have access to the import locations. |
|

|
|
This import information has to be explicitly provided to Solidity through Mythril. |

We can do this by providing the remapping information to Mythril as follows: |

Here we are mapping the import ``@openzeppelin/contracts/token/PRC20/`` to the path which contains ``PRC20.sol`` which in this case |

in the path ``node_modules/PRC20`` in our file system. We feed to file to Mythril using ``--solc-json`` argument. |
