解决FileNotFoundError: [Errno 2] No such file or directory: 'pdflatex': 'pdflatex'报错问题

在ubuntu使用anaconda环境安装scapy,打开时会报错没有PyX
于是安装PyX

pip --default-timeout=100 install -U PyX

安装完后，一打开发现scapy直接打开失败了

FileNotFoundError: [Errno 2] No such file or directory: 'pdflatex': 'pdflatex'

问题出在这

   FileNotFoundError: [Errno 2] No such file or directory: 'pdflatex': 'pdflatex'

知道问题后，于是试着输入分析是不是没有导入pdflatex库，
于是安装库

pip --default-timeout=100 install -U pdflatex

导入成功后，但还是失败了，接着又试了下发现系统没有安装pdflatex这个应用
于是根据系统提示进行安装

sudo apt install texlive-latex-base

安装完后再sudo scapy发现可以运行了，成功解决问题
