crypto.hash error
I'd like to start a new nuxt v4 project. But I seems to get this error.
I updated node to the latest version, and downgraded vite to version 5.
Nothing works. Can somebody help?

Hi @Christoph Pfrommer. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
----------------------
The "crypto.hash is not a function" error when starting a new Nuxt v4 project is a known issue that has been reported by several users. This error often appears when running the Nuxt dev server, especially when using Bun as the runtime, but it can also be related to Node.js or Vite versions.
Key points from the knowledge sources:
- One user encountered this error and found that running the project with Bun (
bun run --bun dev) was necessary to avoid the crypto.hash is not a function error, but still experienced other issues with HMR and dev server stability. They also had Node.js v20.12.2 installed alongside Bun, suggesting that the runtime environment can impact this error. However, even with the workaround, other dev server issues persisted, especially with Bun as the runtime [Nuxt dev server issues].
- Another user resolved similar dev server issues by reinstalling Node.js using a version manager (like fnm or nvm), which suggests that a clean and up-to-date Node.js installation can help resolve some environment-related errors [Nuxt dev server issues].
- The official Nuxt documentation recommends using Node.js 20.x or newer (preferably the active LTS release) for Nuxt 4 projects. It also notes that if you are using Bun, you should ensure Node.js is installed, as Bun may rely on it for certain features [Nuxt 4 Installation].
What you can try:
1. Ensure Node.js is installed and up-to-date (preferably Node 20.x LTS or newer, and use an even-numbered version).
2. If using Bun, make sure Node.js is also installed on your system, as Bun may piggyback off Node for some features.
3. Try running your project with Node.js instead of Bun to see if the error persists.
4. If you have both Bun and Node.js, try switching your runtime (e.g., use npm run dev instead of bun run dev).
5. If you still encounter issues, try reinstalling Node.js using a version manager like nvm or fnm to ensure a clean environment.
If after these steps the error persists, it may be related to a deeper compatibility issue between Nuxt, Vite, and your runtime environment. The knowledge sources do not provide a definitive fix for the crypto.hash is not a function error, but environment cleanup and ensuring the correct runtime are the most common recommendations from users who have faced similar issues.
If you can share more details about your environment (OS, Node.js version, Bun version, how you are running the dev server), it may help narrow down the cause further.
