installing kableExtra fails without explanation

[allefeld]

If I try to install kableExtra in the webR REPL app using install(kableExtra) and then confirming that I want to try downloading it, first a bunch of packages are downloaded, and then nothing more happens:

> library(kableExtra)
Failed to load package "kableExtra". Do you want to try downloading it from the webR binary repo?

Thank you for reporting this! It looks like this is an issue with our WebAssembly build of the FreeType library in the latest webR builds. The issue is in the symbol _ZN13FreetypeCacheC1Ev trying to call FT_Init_FreeType.

In the meantime, the following previous version of webR should work: https://webr.r-wasm.org/v0.4.2/
