Error "incompatible architecture (have (x86_64), need (arm64e))" trying to start FRET on an M1 machine

[tflinkow]

On an Apple M1 machine I get the following error when trying to start the application:

App threw an error during load
Error: dlopen(/Users/thomasflinkow/Downloads/fret-2.3/fret-electron/app/node_modules/leveldown/build/Release/leveldown.node, 0x0001): tried: '/Users/thomasflinkow/Downloads/fret-2.3/fret-electron/app/node_modules/leveldown/build/Release/leveldown.node' (mach-o file, but is an incompatible architecture (have (x86_64), need (arm64e)))

I have attached the full output of running npm start -dd in file start.txt.

I have the required prerequisites installed:

thomasflinkow@Thomass-MacBook-Pro fret-2.3 % node --version
v16.16.0
thomasflinkow@Thomass-MacBook-Pro fret-2.3 % python --version
Python 3.10.6

and the installation seems to be successful too (attached is a file installation.txt containing the output of running npm run fret-install -dd).

I would appreciate any help in getting FRET to work on my machine and thank you in advance.

Please let me know if you need any other information.

Hi @flinkow,

FRET uses pouchdb and pouchdb has a dependency on the leveldown package. M1 machines need leveldown version ^6.0.3 but the current pouchdb configuration requires leveldown version 5.6.0 (see pouchdb/pouchdb#8526).

Until the pouchdb team fixes this dependency issue, you can apply the fix below.

After cloning FRET:

1. cd fret/fret-electron
2. npm run fret-install
3. cd app (under fret/fret-electron/)
4. npm install leveldown@latest
5. Edit package-lock.json (under fret/fret-electron/app/)

• Change leveldown dependency: “^5.4.0” under node_modules/level to “^6.0.3”
• Change leveldown dependency: “5.6.0” under node_modules/pouchdb to “^6.0.3”

6. cd ..
7. npm start

Let us know if that works!

Thank you very much for the quick reply and the proposed workaround (it works fine).

Thank you. I am closing this issue.
