error in 'npm run build'

[hedgy123]

Thanks so much for making your code available on github! I tried following your build instructions, and got the following errors while running 'npm run build':

> lettier-lda-topic-modeling@ modify-worker-0 /Users/<USERNAME>/lda-topic-modeling
> sed -i '/var PS = {};/a self.PS = PS;' output1/_worker.js

Do you know what I can do to fix this? Thanks very much!

Hello @hedgy123,

What OS are you using?

You can try replacing this line

"modify-worker-0": "sed -i '/var PS = {};/a self.PS = PS;' output1/_worker.js",

with this line

"modify-worker-0": "sed -i '' -e '/var PS = {};/a self.PS = PS;' output1/_worker.js",

in package.json.
