Fix OnFatalError
in pnpm
✅ Solution
The "OnFatalError" error in pnpm, often manifesting as "JavaScript heap out of memory," usually arises from insufficient memory allocated to Node.js during dependency installation, especially with large projects. Increase the Node.js heap size by setting the `NODE_OPTIONS` environment variable before running pnpm install, for example, `NODE_OPTIONS="--max-old-space-size=4096" pnpm install`. You can also try using a smaller, more targeted install by specifying particular dependencies.
