"The namespace 'Photon.Chat' already contains a definition for"エラーが出る場合

以下エラーが出る場合

Assets/PhotonChatApi/ChannelCreationOptions.cs(9,18): error CS0101: The namespace 'Photon.Chat' already contains a definition for 'ChannelCreationOptions'

以下２つあるのでどちらかを消す。かと思ったが、photon1についてるchatを使うので、そもそもphoton_chatはインストールしない

• Photon/PhotonChat/Code/ChannelCreationOption
• Photon/PhotonChatApi/ChannelCreationOption

以下エラーが出る場合

Assets/PhotonChatApi/ChannelWellKnownProperties.cs(9,18): error CS0101: The namespace 'Photon.Chat' already contains a definition for 'ChannelWellKnownProperties'

以下２つあるのでどちらかを消す。かと思ったが、photon1についてるchatを使うので、そもそもphoton_chatはインストールしない

• Photon/PhotonChat/Code/ChannelWelKnownProperties
• Photon/PhotonChatApi/ChannelWelKnownProperties
