writeBigUInt64BE is not a function #301

Closed dekadentno closed 3 years ago

dekadentno commented 3 years ago

I am trying to access writeBigUInt64BE like in the codesandbox below: https://codesandbox.io/s/stoic-bohr-bnsir

but the error states that 

Buffer.prototype.writeBigUInt64BE is not a function

although it is exported as seen here: https://github1s.com/feross/buffer/blob/HEAD/index.js#L1542-L1543 Functions like writeIntLE are exported in the same way and they can be accessed.

Note: typeof BigInt returns function in my browser.

You may need import { Buffer } from "buffer/" (note the slash) rather than import { Buffer } from "buffer", in order to import the buffer npm package rather than the shim that the bundler injects, which may be an older version of buffer.

Thank you for your answer. I managed to do that in my codesandbox above, but writeBigUInt64BE is still undefined in my local vue project.

Steps to reproduce error:

git clone https://github.com/dekadentno/buffer-test
cd buffer-test
npm i
npm run serve

I know this may not be the place to ask this, but I hope you may know the answer. I also assume this may be a webpack/babel issue, but I cannot be certain.

The issue was in the import. Even import { Buffer } from "buffer/" // notice the slash didn't help me, I had to import it this way import { Buffer } from 'buffer/index.js' because it was picking up node_modules/node-libs-browser/node_modules/buffer/index.js instead of node_modules/buffer/index.js.

I don't know if it should be noted in the docs and if anyone had a similar issue.
