As of 2020.11.03, the latest version of Solidity is 0.7.2. You can use the following command to view the current solidity version supported by truffle:
truffle compile --list --all
It should be pointed out that truffle v5.1.45 currently supports soljson versions from v0.1.1 to v0.7.1, and it does not support solidity v0.7.2. If you want to support the v0.7.2 version, please upgrade the truffle version as well.
1. Copy the solidity compilation list of https://github.com/ethereum/solc-bin/tree/gh-pages/bin to solVersion.txt
2. Remove the line where the keyword is specified in solVersion.txt
