I try newArch and downloadBoost runs twice same time

[pnthach95]

So RN 0.70 is just released and I try it with newArchEnabled=true and Reanimated 2.10.0. It runs downloadBoost twice same time, see screenshot below:

Is there a way to make it run once?

Hey, you're right, we could use the boost archive downloaded by react-native. We plan to address this issue in near future.

As for now, you can set environmental variable REACT_NATIVE_DOWNLOADS_DIR and both React Native and Reanimated will check if boost, glog etc. is present there:

mkdir -p /Users/<username>/.react-native/downloads

You can add this line to your ~/.zshrc (or other):

export REACT_NATIVE_DOWNLOADS_DIR=/Users/<username>/.react-native/downloads 

Don't forget to apply the changes in the current console:

source ~/.zshrc

Note: For existing project this trick works after project clean.
