Error compiling TypeScript project on Solana: Unable to compile anchor TypeScript project

The issue you are experiencing is due to a mismatch between the TypeScript compiler and the « @coral-xyz/anchor » package. Specifically, the error occurs when trying to compile the project using the « tsc » command.

To resolve this issue, please follow these steps:

Step 1: Check your TypeScript version

Make sure you are using the latest version of TypeScript (>= 4.7). If you are still using an older version, consider upgrading to the latest version.

npx tsc --version

Step 2: Install « @coral-xyz/anchor » with the correct version

You need to install the latest version of @coral-xyz/anchor. Run the following command:

npm install --save @coral-xyz/anchor@latest





or
add yarn @coral-xyz/anchor@latest

Step 3: Update tsconfig.json'

Update thetsconfig.json’ file to include the configuration required to compile TypeScript with tsc. Add the following lines:

{
"compilerOptions": {
// ...
"target": "es6",
"lib": ["dom", "esnext"],
// ...
}
}

Replace es6' with the target version you want (for example,es5′ if you prefer older JavaScript).

Step 4: Recompile the project

After making your changes, recompile your TypeScript project using the « tsc » command.

npx tsc

or
background tsc

If you encounter any issues while compiling, make sure that:

• You have installed all required dependencies (@coral-xyz/anchor) and their transpilers.

• Your TypeScript version is compatible with@coral-xyz/anchor.

• The compiler settings are set correctly intsconfig.json’.

If you are still having issues, feel free to share the error message or relevant code snippets. I’d be happy to help you troubleshoot further!
