I am current trying to build a solana calculator project on my mac(M3 version), mostly duplicate the code what I learned on Udemy. So basically I am trying run the same of the teacher on my pc successfully.

What i use:
Anchor
Mocha
node_modules/@project-serum
solana

What I did:

1. use anchor init to create a project
2. anchor build(i can build without errors)
3. Add some code to lib.rs file:

    use anchor_lang::prelude::*;

    declare_id!("CfaDqW3stWavnEn8KZLnqSLbmTzUjhn3aNawSCtsVbGu");

    #[program]
    pub mod mycalculatordapp {
        use super::*;
        pub fn create(ctx: Context<Create>, init_message: String) -> Result<()> {
            let calculator = &mut ctx.accounts.calculator;
            calculator.greeting = init_message;
            Ok(())
        }
     }

    #[derive(Accounts)]
    pub struct Create<'info>{
        #[account(init, payer=user, space=264)]
        pub calculator: Account<'info, Calculator>,
        #[account(mut)]
       pub user: Signer<'info>,
       pub system_program: Program<'info, System>
    }

    #[account]
    pub struct Calculator {
        pub greeting: String,
        pub result: i64,
        pub remainder: i64
    }

4. Add a simple test code to mycalculatordapp.ts file:

const assert = require('assert');
const anchor = require('@project-serum/anchor');
const { SystemProgram } = anchor.web3;

describe('mycalculatordapp', () => {
  const provider = anchor.Provider.local();
});

And then I got this Error when I run ‘anchor test’ on my terminal:

TypeError: Cannot read properties of undefined (reading ‘local’)

I have tried my ways but just can’t not solve this issue, hope some professionals can take a look and give me a insight.

I have check all the dependencies, which should be installed correctly. The problem will be very likely to caused by this line:

const provider = anchor.Provider.local();

I am not sure is there a environmental set up error of any other issue, just can’t pass this.
