I don't know if it's helpful to mention that I am also experiencing this error; feel free to delete this comment if it's just noisy/duplicative. But I wanted to say that it might make sense to add a temporary note to the installation guide explaining that the npm method isn't working on macOS until the problem is resolved; I was confused & it took me a bit of searching to find this issue.

[ispivey]

This should be resolved as of a few minutes ago, when we deployed a (putative) fix. @robinsloan can you try again? If you're still seeing errors, please re-open this issue and share the error message you see!

[robinsloan]

Success! I feel honored to know I might have been the last person in the universe to experience this error. Thanks!

@ispivey When I try to preview my project using wrangler preview --watch or wrangler preview, I keep getting this message:
"Error: Your JavaScript project is missing a package.json file; is /home/swatilekha/hello the wrong directory?"
Could someone kindly help me out on that? Thanks.
