Debian 9 (Stretch) 安装poppler 0.73.0与R pdftools包报错求助

我一直在Debian 9.13 (stretch)设备上尝试安装更高版本的poppler，编译过程一切正常，但安装R的pdftools包时一直报错，求解决方法。

我之前参照相关指南执行了如下操作：

sudo apt purge libpoppler-cpp-dev
sudo apt-get install libopenjp2-7-dev libgdk-pixbuf2.0-dev cmake checkinstall
sudo apt-get build-dep libpoppler-cpp-dev
cd 
wget https://poppler.freedesktop.org/poppler-0.73.0.tar.xz
tar -xf poppler-0.73.0.tar.xz
cd poppler-0.73.0
mkdir build
cd build
cmake ..
sudo checkinstall make install

上述操作执行完成后返回如下结果：

Done. The new package has been installed and saved to

 /home/admonda/poppler-0.73.0/build/poppler_0.73.0-1_amd64.deb

 You can remove it from your system anytime using: 

      dpkg -r poppler

随后我执行了以下命令，执行后无返回内容：
echo "export R_LD_LIBRARY_PATH=\$R_LD_LIBRARY_PATH:/usr/local/lib" >> .bashrc

之后我打开R控制台执行pdftools包安装命令，安装过程报错，报错日志如下：

报错核心是系统动态链接库没有识别到你编译安装到/usr/local/lib路径下的poppler库文件，你之前的操作漏了更新缓存和生效环境变量的步骤，按以下顺序执行即可：

• 第一步：更新系统动态链接库缓存，让系统识别新安装的so文件
  sudo ldconfig
• 第二步：验证库文件确实存在，执行以下命令如果有输出则为正常
  ls /usr/local/lib | grep libpoppler-cpp.so.0
• 第三步：生效你之前写入.bashrc的环境变量，避免R读不到路径配置
  source ~/.bashrc
• 第四步：在当前终端直接打开R，重新安装pdftools即可
  install.packages("pdftools")

如果以上操作还是报错，可以用强制指定库路径的方式启动R后再安装：
LD_LIBRARY_PATH=/usr/local/lib R
