run script error: Library not loaded, FlutterEmbedder #3

Open canadaduane opened 5 years ago

canadaduane commented 5 years ago

I'm starting a fresh project using the latest flutter version, but when I run ./scripts/run.py I get the following error at the end of the compilation steps:

   ...
   Compiling tokio-tcp v0.1.3
   Compiling tokio v0.1.18
   Compiling cargo_toml v0.4.0
   Compiling flutter-engine v0.2.1
   Compiling shannon_editor v0.1.0 (/Users/duane/Projects/flutter-app/rust)
    Finished dev [unoptimized + debuginfo] target(s) in 1m 01s

dyld: Library not loaded: @rpath/FlutterEmbedder.framework/Versions/A/FlutterEmbedder
  Referenced from: /Users/duane/Projects/flutter-app/rust/target/debug/shannon_editor

I'm not sure what @rpath should expand to, so I'm not sure where to look for this library.

Author's another repo has a pre-need config. Add these to .bash_profile will fix.

Can you try again? This one is strange though. I usually succeed on the second try. It's like the compiler takes time to find the framework.

I re-installed all the latest versions of everything, and it works as you say. Fails the first time; works the second time.

First try:

   Compiling flutter-engine v0.3.2
warning: crate `DTest` should have a snake case name
  |
  = note: #[warn(non_snake_case)] on by default
  = help: convert the identifier to snake case: `dtest`

    Finished dev [unoptimized + debuginfo] target(s) in 1m 50s
     Running `target/debug/DTest`

Yes, for some reason the compiler failed to find the framework, the first time it's compiled after downloading from network.
