Ha, weird. It looks like npm is installing an almost empty @microsoft/load-themed-styles module:

Did you publish an empty module by accident?

Me too! I even uninstalled node.js and npm, reinstalled node 9.4 (npm 5.6) and create-react-app, then followed the instructions in the readme.md to the letter to create DocumentCardBasic with same error reported above.

Any idea how to work around this? Our package.json in our project specifically references 5.38.1, however VSTS build seems to be getting whatever's the latest version regardless, which is this broken build.

Cheers jimmywim!
Installed previous version and it works!
npm install --no-save @microsoft/[email protected]

Looks like there was a hiccup in the release process yesterday. I went ahead and unpublished 1.7.26, so you should be getting 1.7.25 when you npm install @microsoft/load-themed-styles@latest. Let me know if you are experiencing the problem with any other packages.

closing this down as it appears resolved. feel free to open if problem persists.

I ran into this today. Had to manually run "npm install @microsoft/load-themed-styles@latest" against a fresh clone to get "npm install" to complete.
