我正在嘗試從Datastax網站構建cpp-driver。我在Ubuntu 12.04上。在說明書中寫入將ppa:linuxjedi/ppa添加到存儲庫,以便安裝libuv。但我越來越在Ubuntu 12.04上安裝libuv
Package libuv-dev is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'libuv-dev' has no installation candidate
當我嘗試做一個更新後,添加ppa。在ubuntu 12.04上安裝libuv有沒有其他選擇?
