Analysis of Errors and Solutions for Solana Compilation Issues

As a developer working on building programs for the Solana blockchain, it is not uncommon to encounter issues during the compilation process. The error message “bigint: Failed to load binding, will use pure JS” indicates that the program is having trouble loading the required dependencies. In this article, we will break down the issue and provide a step-by-step solution to resolve it.

Understanding the Error

The error message suggests that there are issues with the Solana blockchain’s bigint module, which is required to build programs on-chain. Binding pure JS implies that JavaScript is being used instead of the Solana JavaScript Runtime (JSR). This can happen when npm is not configured correctly or when there is a problem with the version of npm or solana-js.

Causes of the error

There are several possible causes for this error:

  • npm version issues: Outdated or corrupted npm packages may be the cause of the problem.
  • Solana JavaScript runtime (JSR) dependency issues: The Solana team recently released new versions of their JSR and there is a possible compatibility issue between the old and newer versions.
  • NPM update

    : Upgrading npm may resolve the issue.

Solution: Update npm and its dependencies

To resolve the error, we will need to perform the following steps:

Step 1: Update npm

First, let’s make sure that npm is up to date by running:

 »just like that

npm update

This command will update all the packages in your project, including npm itself.

Step 2: Install bigint-buffer and solana-js
Next, we need to install the bigint-buffer package and the Solana JavaScript Runtime (JSR) using npm. We will use the following commands:
''just like this
npm install bigint-buffer
npm install solana-js

These packages must be compatible with each other.

Step 3: Rebuild the project

Once you have installed the necessary dependencies, it is time to rebuild your project:

 »just like this

npm run build

This command will recompile all the scripts and assets in your project.

Step 4: Run the anchor test script
Finally, we can run the anchor test script to verify that everything is working as expected:

npm run anchor test
