包名与官网不符

[tz12323]

mcpp add json@3.12.0
  Refreshing package index — `json` not found locally (one-time)
error: package 'json' not found in any configured index
  tried: (mcpplibs, json), (no namespace, json)
  a package with this name exists under another namespace:
    nlohmann.json
  hint: `mcpp index update` if it was published recently

mcpp add tomlplusplus@3.4.0
error: package 'tomlplusplus' not found in any configured index
  tried: (mcpplibs, tomlplusplus), (no namespace, tomlplusplus)
  a package with this name exists under another namespace:
    marzer.tomlplusplus
  hint: `mcpp index update` if it was published recently

目前我发现json和tomlplusplus的实际包名和官网中不符合
