compiler problem with solidity and truffle

Asked 2021-Jun-12 at 18:56

So I'm trying to learn to build NF token, and I cloned a repo. It's supposed to work with truffle. The thing is I have an error with the compiler, and I don't really understand. Indeed what I know is that the solidity compiler have problems with different versions, hence working with truffle CLI that works better with different versions projects.

So I tried to change to "pragma solidity >0.5.8 <0.6.0;", I did sudo truffle compile, and still have the error.

The error message I got is:

my typo `Source file requires different compiler version (current compiler is 0.7.4+commit.3f05b770.Emscripten.clang) - note that nightly builds are considered to be strictly less than the released version

I know that I need to find a good version of solidity and truffle, but I believe that my versions are okay :

Truffle v5.0.5 (core: 5.0.5) Solidity v0.5.0 (solc-js) Node v14.16.0

You should put your call to "callback" inside of the promise resolution. Otherwise, "callback" gets executed before your promise is resolved.

Web3.js contract objects are different from Truffle contract objects. There are slight differences in the structure and of course, because it is all untyped JavaScript, you have no idea what inputs or outputs functions are going to have.

Historically, Ethereum transactions did not have return values. Web3.js behavior predates this time, and might not support returning the transaction value directly. However EIP 1288 document how the return value is available through getTransactionReceipt() and receipt object.

To have Web3.js to modify EVM state you need to do send() instead of call(). This is yet another weakly typed issue, as one should not confuse view and write functions.

When I set storedData to be public, then it works fined.

You aren't using solc-js correctly. You need to stringify the input, and you're passing a 1 instead of an import callback. Please read the docs before posting questions: https://github.com/ethereum/solc-js

Consider using etherjs, much better documentation and more robust than web3.
