Error: Source "@openzeppelin/contracts/token/ERC721/ERC721.sol" not found: File not found. Searched the following locations: "".
Currently, all dependencies from @openzeppelin are showing errors like this. But those dependencies have been installed in my node_modules and I don't know why it can't find the file. Is there a way I can set the location, or should I install the @openzeppelin/contracts globally?
UPDATE：I can see that --base-path should be set for solc, but I am still not sure how to apply such setting to slither.
I found a (might be dirty) way to solve it:
Step 1: Go to the directory where all your dependencies are.
In my case, do cd node_modules
Step 2: Call the same command with the updated relative path.
In my case, from slither contracts/MyContract.sol to slither ../contracts/MyContract.sol
And it just works. After going through the doc, I don't think Slither is providing a way to adjust --base-path as a flag.
