Hi,  
I have the following error when I do "brownie compile"

Invalid command. Try 'brownie --help' for available commands.  
PS C:\Users\Admin\nft project\> brownie compile  
INFO: Could not find files for the given pattern(s).  
Compiling contracts...  
Solc version: 0.6.6  
Optimizer: Enabled Runs: 200  
EVM Version: Istanbul  
CompilerError: solc returned the following errors:

import "@openzeppelin/contracts/token/ERC721/ERC721.sol";  
^-------------------------------------------------------^

the code on my contract is the following:

```auto
//SPDX-Licence-Identifier:<SPDX-Licence>

pragma solidity ^0.6.6;

import "@openzeppelin/contracts/token/ERC721/ERC721.sol";

contract simplecollectibe is ERC721 {

    uint256 public tokencounter;

    constructor () ERC721("Dogie","DOG") public {

        tokencounter= 0;

    }

    function createCollectible() public returns (uint256){

        uint256 newtokenid=tokencounter;

        _safeMint(msg.sender,newtokenid);

        tokencounter= tokencounter + 1;

        return newtokenid;

    }

}

```

any suggestions on how to fix it? thanks!!

Hi, I think you can use this command to have a try:

```auto
brownie pm install OpenZeppelin/openzeppelin-contracts

```

@Skyge thanks for your help. But it is still giving me the same error:

SUCCESS: Package 'OpenZeppelin/openzeppelin-contracts@3.0.0' has been installed  
PS C:\Users\Admin\nft project\> brownie compile

Any other ideas? thanks

Just read the Brownie documentation: [The Configuration File | Brownie 1.17.2](https://eth-brownie.readthedocs.io/en/stable/config.html#the-configuration-file) so it seems like you should make a new file named `brownie-config.yaml`, use the keyword `remap` to import what you will use in the package, just like:

```auto
dependencies:
  - OpenZeppelin/openzeppelin-contracts@3.0.0
compiler:
  solc:
    remappings:
      - '@openzeppelin=OpenZeppelin/openzeppelin-contracts@3.0.0'

```
