【问题描述】：
我正在尝试搭建deepmind/dqn的环境，https://github.com/deepmind/dqn，我运行./install_dependencies.sh来安装
LuaJIT and Torch 7.0
nngraph
Xitari
AleWrap
首先。但我得到了：
/home/dqn/torch/bin/luajit: error while loading shared libraries: libreadline.so.7: cannot open shared object file: No such file or directory
- => Torch7 has been installed successfully
Installing nngraph ... /home/dqn/torch/bin/luajit: error while
loading shared libraries: libreadline.so.7: cannot open shared object
file: No such file or directory Error. Exiting.
install_dependencies.sh 是：
# Install dependencies for Torch:
sudo apt-get update
sudo apt-get install -qqy build-essential
sudo apt-get install -qqy gcc g++
sudo apt-get install -qqy cmake
sudo apt-get install -qqy curl
sudo apt-get install -qqy libreadline-dev
sudo apt-get install -qqy git-core
sudo apt-get install -qqy libjpeg-dev
sudo apt-get install -qqy libpng-dev
sudo apt-get install -qqy ncurses-dev
sudo apt-get install -qqy imagemagick
sudo apt-get install -qqy unzip
sudo apt-get update
echo "==> Torch7's dependencies have been installed"
# Build and install Torch7
cd /tmp
rm -rf luajit-rocks
git clone https://github.com/torch/luajit-rocks.git
cd luajit-rocks
mkdir -p build
cd build
git checkout master; git pull
rm -f CMakeCache.txt
cmake .. -DCMAKE_INSTALL_PREFIX=$PREFIX -DCMAKE_BUILD_TYPE=Release
RET=$?; if [ $RET -ne 0 ]; then echo "Error. Exiting."; exit $RET; fi
make
RET=$?; if [ $RET -ne 0 ]; then echo "Error. Exiting."; exit $RET; fi
make install
RET=$?; if [ $RET -ne 0 ]; then echo "Error. Exiting."; exit $RET; fi
path_to_nvcc=$(which nvcc)
if [ -x "$path_to_nvcc" ]
then
cutorch=ok
cunn=ok
fi

echo ""
echo "=> Torch7 has been installed successfully"
echo ""
echo "Installing nngraph ... "
$PREFIX/bin/luarocks install nngraph
RET=$?; if [ $RET -ne 0 ]; then echo "Error. Exiting."; exit $RET; fi
echo "nngraph installation completed"
echo "Installing Xitari ... "
cd /tmp
rm -rf xitari
git clone https://github.com/deepmind/xitari.git
cd xitari
$PREFIX/bin/luarocks make
RET=$?; if [ $RET -ne 0 ]; then echo "Error. Exiting."; exit $RET; fi
echo "Xitari installation completed"
echo "Installing Alewrap ... "
cd /tmp
rm -rf alewrap
git clone https://github.com/deepmind/alewrap.git
cd alewrap
$PREFIX/bin/luarocks make
RET=$?; if [ $RET -ne 0 ]; then echo "Error. Exiting."; exit $RET; fi
echo "Alewrap installation completed"
echo
echo "You can run experiments by executing: "
echo
echo " ./run_cpu game_name"
echo
echo " or "
echo
echo " ./run_gpu game_name"
echo
echo "For this you need to provide the rom files of the respective games (game_name.bin) in the roms/ directory"
echo
当我测试代码 ./run_gpu {game_name} 时，我得到：
../torch/bin/luajit: error while loading shared libraries: libreadline.so.7: cannot open shared object file: No such file or directory
当我运行 ldconfig -p | grep 读取行 我的版本低于6
libreadline.so.6 (libc6,x86-64) => /lib/x86_64-linux-gnu/libreadline.so.6
libreadline.so (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libreadline.so
libguilereadline-v-18.so.18 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libguilereadline-v-18.so.18
libguilereadline-v-18.so (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libguilereadline-v-18.so
但我无法通过以下方式安装 libreadline7：sudo apt-get install libreadline7-dev
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package libreadline7-dev
如何解决 libreadline7 的安装问题？
