ReferenceError: $ is not defined

[joetoth]

I'm guessing something with npm isn't compiling correctly? Any idea how to debug?

ReferenceError: $ is not defined

having the same issue while experimenting with the react server, which refuses to work with this ^_ error in the webbrowser console

[wuxxin]

@pokowaka do you have any idea why this happens ?

[pokowaka]

Hi,

Do you have some steps to reproduce this?

[wuxxin]

Hi, thank you for your answer, steps to reproduce:

• base system: ubuntu eoan (19.10):

sudo apt-get install libprotobuf-dev libprotoc-dev protobuf-compiler npm
sudo npm i yalc -g
git clone https://github.com/google/android-emulator-container-scripts.git
cd android-emulator-container-scripts
. ./configure.sh
./create_web_container.sh -p user,pass
# takes a long time to complete, no errors are thrown, a few warnings are thrown
# warnings on the bottom of the issue
docker-compose -f js/docker/docker-compose-build.yaml up

• in another terminal, wait until "emulator_emulator:latest" has health!=starting

docker ps

[pokowaka]

Able to reproduce this on ubuntu gce cloud instance.

[pokowaka]

We use sed to inject markers in the generated protobuf files to make sure that react disables linting for the files.

It looks like either:

• sed is not behaving as expected on all platforms
• make is not behaving as expected on all platforms

Will replace sed with python scripts to reduce platform issues.

@pokowaka thank you, i just tried it out, and i can report success on ubuntu 20.04 (focal), it works as expected
