我按照以下说明在 Ubuntu 18.04 上设置了 pdftk:
sudo add-apt-repository ppa:malteworld/ppa
sudo apt update
sudo apt install pdftk
取自之前问过的Askubuntu 问题。我使用 Node 的包装器 Scissors.js 构建了一个快速应用程序来操作多个 PDF。它在我的 Mac 上运行良好,但在 Ubuntu Server 上测试代码时,我在尝试编辑 PDF 时遇到以下错误。
我是否设置了错误的 pdftk repo?

答案1
我使用了以下命令并且能够重新安装 pdftk 而不存在此库错误:
cd /tmp
# download packages
wget http://mirrors.kernel.org/ubuntu/pool/main/g/gcc-6/libgcj17_6.4.0-8ubuntu1_amd64.deb \
http://mirrors.kernel.org/ubuntu/pool/main/g/gcc-defaults/libgcj-common_6.4-3ubuntu1_all.deb \
http://mirrors.kernel.org/ubuntu/pool/universe/p/pdftk/pdftk_2.02-4build1_amd64.deb \
http://mirrors.kernel.org/ubuntu/pool/universe/p/pdftk/pdftk-dbg_2.02-4build1_amd64.deb
echo -e "Packages for pdftk downloaded\n\n"
# install packages
echo -e "\n\n Installing pdftk: \n\n"
sudo apt-get install ./libgcj17_6.4.0-8ubuntu1_amd64.deb \
./libgcj-common_6.4-3ubuntu1_all.deb \
./pdftk_2.02-4build1_amd64.deb \
./pdftk-dbg_2.02-4build1_amd64.deb
echo -e "\n\n pdftk installed\n"
echo -e " try it in shell with: > pdftk \n"
# delete deb files in /tmp directory
rm ./libgcj17_6.4.0-8ubuntu1_amd64.deb
rm ./libgcj-common_6.4-3ubuntu1_all.deb
rm ./pdftk_2.02-4build1_amd64.deb
rm ./pdftk-dbg_2.02-4build1_amd64.deb
答案2
下面的包装脚本为我解决了这个问题(到目前为止,可能需要更多的库):
#!/bin/bash
/usr/bin/java -cp /usr/share/java/commons-lang3.jar:/usr/local/bin/pdftk.jar pdftk "$@"
由于我没有进一步关注或验证的原因,使用 java -jar 运行应用程序时,classpath(-cp)选项似乎不起作用
您可能需要调整路径到正确的位置。
