Time out connect to ffx component run "fuchsia-pkg://fuchsiasamples.com/hello_world#meta/hello_world.cm"

Question

My system is MacOS and I have already build fuchsia, but when I run the command line

 fuchsia % ffx component run "fuchsia-pkg://fuchsiasamples.com/hello_world#meta/hello_world.cm" 
Timeout attempting to reach target "unspecified"

this error occurred.

Hmmm.. I think it is because I am in China but I've already used VPN Is there any solutions

Thank you so much!

My system is MacOS and I have already build fuchsia...

Since you mentioned you are building Fuchsia yourself, make sure any guidance you follow comes from the Platform Source side of Fuchsia.dev.

ffx component run "fuchsia-pkg://fuchsiasamples.com/hello_world#meta/hello_world.cm"

This looks like you might be following the Get Started with the SDK developer guide, which is not intended for developers who have the source tree and are building Fuchsia.

Timeout attempting to reach target "unspecified"

Based on the above comments, this can happen if you are mixing versions of ffx between the SDK and a local source tree build (for example, in two different terminal windows that have a different PATH configured). So make sure all commands you run are using the same ffx binary.

Beyond that, this generally means that the ffx daemon is unable to communicate with your device or emulator instance (i.e. it doesn't appear in ffx target list). The most common causes are:

1. Firewall rules aren't set up correctly
2. SSH keys on the device don't match the host
