❓ Troubleshooting

First of all, make sure the version of flutter and rust is the version specified in here

1. Protobuf Generation Errors

Ensure the protoc-gen is installed

which protoc-gen-dart

Ensure the $HOME/.pub-cache/bin is shown in your $PATH.

echo $PATH

Ensure VS Code uses bash as the default terminal You can check out this link for more information.

2. Remove outdated files

AppFlowy uses CodeGen to generate some files that are ignored by git. So remove these files if there are some errors, warnings, and reference errors.

Here are the files are safe to remove

AppFlowy/frontend/app_flowy/packages/flowy_sdk
AppFlowy/frontend/app_flowy/packages/appflowy_backend/lib/dispatch/dart_event
AppFlowy/frontend/app_flowy/packages/appflowy_backend/lib/protobuf

7. Failed to load dynamic library 'libdart_ffi.so'

issue #112 Q: Hello, when I run app with vs code&android&mac m1, it gave error:

ArgumentError (Invalid argument(s): Failed to load dynamic library 'libdart_ffi.so': dlopen failed: library "libdart_ffi.so" not found)

A: Are you trying to build for android? Appflowy only supports desktops as of now

issue #191 Q. Unhandled Exception: Invalid argument(s): Failed to load dynamic library 'libdart_ffi.so' on Ubuntu.

A: I append ubuntu 21.04 source.list's content to /etc/apt/source.list, and then upgrade libc6.

# Append the ubuntu 20.04's source.list to its tail.
$ sudo vim /etc/apt/source.list
$ sudo apt upgrade libc6

8. Build failed on Ubuntu 20.04

issue #106

Q: I follow the BUILD_ON_LINUX.md and failed on step 10 cargo make --profile development-linux-x86 flowy-sdk-dev

To Reproduce Just follow the BUILD_ON_LINUX.md

A: There are some issues in protobuf generation of appflowy on linux. If you skip that step, you can get it working. Protobuf has already been generated and is tracked in the repository. So it will work without regeneration as of now.

9. The document data could not be saved on Ubuntu

issue #1306

10. Can't build development environment

Q. While executing install_linux.sh script at compiling diesel_cli i'm getting following error:

17. Run appyflowy in docker,but it not work: cannot open display: 0

Bug Description

xhost + docker run --rm -v $HOME/.Xauthority:/root/.Xauthority:rw -v /tmp/.X11-unix:/tmp/.X11-unix -v /dev/dri:/dev/dri -v /var/run/dbus/system_bus_socket:/var/run/dbus/system_bus_socket -v appflowy-data:/home/appflowy -e DISPLAY=${DISPLAY} appflowyio/appflowy_client:main

(app_flowy:1): Gtk-WARNING **: 01:27:57.247: cannot open display: :0

I add the param --network=host

and it works

issue: #2458

18. Can't run tests on windows "Failed to load dynamic library"

If you're trying to run tests on windows, but they're failing due to this message:

Invalid argument(s): Failed to load dynamic library
'C:\Users\mathias\AppFlowy\frontend\appflowy_flutter/.sandbox/dart_ffi.dll': error code 126
dart:ffi
open
   ...

Run this command from the frontend directory: cargo make dart_unit_test

Optionally you can run this in bash instead of the above one, but you must be inside the appflowy_flutter directory: flutter test --dart-define=RUST_LOG=INFO -j, --concurrency=1 --coverage
