no solutions to this ?

Does deleting the cache (.cache) help?

[NikosEfthias]

it seemingly helped but the weird thing is that I just pulled the repo from github which didnt have a .cache directory initially.

[NikosEfthias]

@mischnic I dont now why would you close this while it is clearly a bug. Again I am having the same issue and cleaning cache does not help this time

I could build with parcel by doing the following steps :

• remove my global parcel installation, (yarn global remove parcel-bundler)
• install parcel locally (yarn add --dev parcel@next)
• add "start": "parcel src/index.html" in scripts of package.json
• use yarn start to run parcel (since the global parcel command is not available anymore)
