Answer №1

According to this explanation, the use of const is not enabled by default in node.js version 0.10 and requires the --harmony flag for implementation.

The error you encountered is likely due to the use of the const keyword in the index.js file of this specific version of the fs-extra package.

You can refer to this compatibility table for an overview of the support levels for const and let based on node.js versions.

Solving this issue may simply require upgrading your node.js version.

Furthermore, running gitbook as a root user may not be advisable.

Answer №2
