Create Next Docs App failed with Contentlayer

[CMAULTOP]

nothing was fixed, everything worked for me through pnpx. Only this works in rpm:
(where the check mark works)

• Default (Contentlayer)
• Advanced (Contentlayer)
• Default (Next Docs MDX)

Error when Default:

Again, I will say that I tested on github codespaces and I think that there are updated versions and working.

Contentlayer doesn't support Next.js 14 in their peer dependency yet, you have to disable peer deps error and try again. Pnpm won't throw an error for missing peer deps issue, you can use it as a workaround.

[fuma-nama]

Please use Next Docs MDX if you don't need Contentlayer specific functionality

[birchwork]

Modify node_modules/next-contentlayer/package.json, next@"^12 || ^13 || ^14

[fuma-nama]

Surprisingly this PR hasn't been merged: contentlayerdev/contentlayer#576, I'll leave this issue for now until they officially release a fix.

[xXQiuChenXx]

Just add --legacy-peer-deps in your command, and it should work well.

Example: npm install --legacy-peer-deps

[fuma-nama]

According to the state of Contentlayer: contentlayerdev/contentlayer#429, I'll recommend Fumadocs MDX if you don't need any Contentlayer-only features.

[fuma-nama]

Will close this as Next.js 15 RC has been released, we will focus on Fumadocs MDX until Contentlayer has resumed maintenance.
