I am trying to import a library in Remix using:
import "github.com/Arachnid/solidity-stringutils/strings.sol";
However, I get a compilation error that says
Unable to import "undefined": Not Found.
Any idea what wrong could I be doing here?
Your link is broken. This is the correct link: github.com/arachnid/solidity-stringutils/src/strings.sol
You forgot /src part.

I have successfully installed openzeppelin/contracts, but I am unable to import it. It shows me an error which is
Source "#openzeppelin/contracts/access/Ownable.sol" not found: File import callback not supported
Does anyone have any idea? Thanks
Please Check the #openzeppelin/contracts is installed in Correct Directory..
Also What npm version of #openzeppelin/contracts you have installed ? The positon of OpenZepplin Contracts is changed after version 4..
Refer..

I am trying to run the following code to train paddleOCR.
import paddle
import paddle.distributed as dist
But I'm getting this error:
ModuleNotFoundError: No module named 'paddle.distributed'
Even after I have installed paddle-client.
docker pull paddlepaddle/paddle:2.3.0-gpu-cuda11.2-cudnn8
I use this images which can work well.
You can try the paddlepaddle with 2.3.1 version，and quick install can refer to: https://www.paddlepaddle.org.cn/en

I'm trying to test a smart contract which import 0x in brownie ecosystem. I have the following error when importing from explorer or from abi, also it looks like solc doesn't take in count the dependency I've install on my computer
CompilerError: solc returned the following errors:
/home/merklejerk/code/0x-protocol/contracts/zero-ex/contracts/src/external/IFlashWallet.sol:23:1: ParserError: Source "#0x/contracts-utils/contracts/src/v06/interfaces/IOwnableV06.sol" not found: File outside of allowed directories.
import "#0x/contracts-utils/contracts/src/v06/interfaces/IOwnableV06.sol";
^------------------------------------------------------------------------
Probably the compiler does not solve the relative path in the correct way.
Maybe the path of the file you import is wrong or not built properly from the compiler: when importing the file IOwnableV06.sol try to remove the # symbol and replace it with ./ or ../ depending on your project folder structure. For example import "../../0x/the-path-here/File.sol";
Or the file you want to import might not be in the allowed paths:
https://docs.soliditylang.org/en/v0.8.7/using-the-compiler.html#how-it-works
(search for --allow-paths).
So, I'm trying to compile in truffle some open zeppelin ERC20 contracts, but I get the following error:
Error: Error: Could not find
import from any sources; imported from C:/Users/Angel/Documents/blockchain course/ethereum game/solidity/contracts/GameToken.sol
at Object.compile (C:\Users\Angel\AppData\Roaming\npm\node_modules\truffle\build\webpack:\packages\workflow-compile\legacy\index.js:72:1)
Token file:
Migration file:
Any ideas? Thanks!
Regarding the documentation, the correct imports are
import "#openzeppelin/contracts/token/ERC721/ERC721Full.sol";
import "#openzeppelin/contracts/token/ERC721/ERC721Mintable.sol";
For those interested, asked the question on the openzeppelin forums and found a solution:
