When I include both stellar-hd-wallet and stellar-sdk in my project I get errors when requiring them both as stellar-base is included twice which also imports the generated XDR types twice causing the below error.

Any suggestions?

Error: XDR Error:Value is already defined
    at TypeBuilder.define (/code/blockchain-client/node_modules/js-xdr/lib/config.js:341:17)
    at TypeBuilder.typedef (/code/blockchain-client/node_modules/js-xdr/lib/config.js:247:14)
    at /code/blockchain-client/node_modules/stellar-hd-wallet/node_modules/stellar-base/lib/generated/stellar-xdr_generated.js:1:259
    at Object.config (/code/blockchain-client/node_modules/js-xdr/lib/config.js:38:5)
    at Object.<anonymous> (//code/blockchain-client/node_modules/stellar-hd-wallet/node_modules/stellar-base/lib/generated/stellar-xdr_generated.js:1:234)

These are the related deps in my package.json:

"stellar-hd-wallet": "0.0.6",
"stellar-sdk": "^0.9.2"
  • What version of NPM or Yarn are you using? Both packages specify the same version of stellar-base so your package manager should be able to dedupe it for you.

  • I'm using npm version 6.1.0

  • Is there anything else that installs stellar-base besides stellar-hd-wallet or stellar-sdk? It looks like stellar-base is not getting deduped by npm since I see that it's under /node_modules/stellar-hd-wallet/node_modules/stellar-base and it should just be under /node_modules/stellar-base if there's no package conflicts. Can you try running npm ls to see if stellar-base is included by something else?

  • This should happen automatically, but can you run npm dedupe to see if that helps. Or delete node_modules folder and npm install again.
