error: could not compile frame-support.
This is a bug related to Substrate w/ Rust compatibility. Since we use Substrate v2.0.0-rc4, this bug isn't fixed yet.
The working fix is to follow next commands from dappforce-subsocial-node directory:
rustup install nightly-2020-07-12
rustup target add wasm32-unknown-unknown --toolchain nightly-2020-07-12
rustup override set nightly-2020-07-12
