在使用Unity2017和最新的2018版本中會(huì)出現(xiàn)Failed to start Unity Package Manager的提示

根據(jù)提示我們進(jìn)入Editor的log文件（log文件一般在C:\Users\username\AppData\Local\Unity\Editor）中進(jìn)行查看
COMMAND LINE ARGUMENTS:
C:\Program Files\Unity\Unity2018.1\Editor\Unity.exe
[Package Manager] Server::EnsureServerProcessIsRunning -- ReadyRequest exceeded maximum alloted time, ran for [10] seconds
[Package Manager] Server::Kill -- Server was shutdown
[Package Manager] PackageManager Server::Start -- Process restart attempt #2
從這里可以看出packageManager Server 被后臺(tái)的防火墻給殺了
解決辦法：關(guān)閉防火墻，打開(kāi)工程瞳购，然后再打開(kāi)防火墻
