Backpack with-typescript示例编译失败，环境node v8.9.4/npm v5.6.0求助

Hey there, let’s break this down for you—you didn’t make a mistake by following the standard clone-and-install workflow. The root issue is almost certainly tied to your outdated Node.js and npm versions, not a bug in the example (though it’s possible the example doesn’t explicitly note minimum environment requirements).

Here’s why this is happening: #

• Node.js v8.9.4 is way past its end-of-life (it stopped receiving updates in late 2019). Modern tooling like Backpack, TypeScript, and their underlying dependencies (think webpack, Babel, etc.) have long dropped support for such old Node versions. These tools rely on features introduced in newer Node releases that simply don’t exist in v8.x.
• npm 5.6.0 is also extremely outdated. Old npm versions often struggle with dependency resolution, miss peer dependency warnings, or create corrupted node_modules folders—problems that have been fixed in newer npm releases (v8 and above).

How to fix this: #

1. Upgrade Node.js and npm (the most critical step):
   Use a version manager like nvm (Node Version Manager) to install a supported LTS (Long-Term Support) version of Node. As of now, Node v20.x is the active LTS, but even v16.x would work perfectly for this example.

   • If you have nvm installed, run these commands:

     nvm install --lts
     nvm use --lts
     

   This will automatically install a compatible, up-to-date version of npm along with Node.

2. Clean up and reinstall dependencies:

   • Delete your existing node_modules folder and package-lock.json file to wipe out any corrupted or incompatible installs:

     rm -rf node_modules package-lock.json
     

   • Run npm install again with your updated Node/npm environment.

3. Retry compiling:
   Run the example’s build or start script (usually npm run build or npm start)—this should resolve the compilation errors once you’re on a supported environment.

About your unanswered issue: #

Open-source maintainers often have huge backlogs, and issues tied to outdated environments are usually lower priority than bugs in supported setups. If you still run into problems after upgrading, update your existing issue with details about your new Node/npm versions and any new error messages you see—this will make it easier for maintainers to help you out.
