为了安装 mongodb，我想安装这些依赖项，因此当我运行此命令时
sudo apt-get install curl tcsh scons g++ xulrunner-1.9-dev libpcre++-dev libboost-dev libmozjs-dev
给我这个结果：
Building dependency tree
Reading state information... Done
Note, selecting 'libmozjs185-dev' instead of 'libmozjs-dev'
g++ is already the newest version.
g++ set to manually installed.
curl is already the newest version.
