debian使用pdf2image包 将pdf转化成图片 Poppler安装出问题

原先用debian9.8 安上了，后来重装了一下debian9.11就安不上了？？？？？？？？？？？

咱也不知道咋回事，就是报这个错，

Traceback (most recent call last):
  File "/home/zh/app/anaconda/lib/python3.7/site-packages/pdf2image/pdf2image.py", line 350, in _page_count

During handling of the above exception, another exception occurred:

pdf2image.exceptions.PDFInfoNotInstalledError: Unable to get page count. Is poppler installed and in PATH?

从网上搜Poppler 安装 Poppler debian Poppler ubuntu 都找不住原因，

sudo apt-get install python-poppler 

像这种也安了不少，
下载了包之后 cmake make 的也有，就是不行。。。。。。。。。。WTF？
后来我想原先是从pdf转图片入手的，也许这个是问题，换个关键词嗖嗖，
直到 我搜 pdf转图片 pdf2image 这才从pdf2image的官网上的某不起眼的一行找到了解决办法

最后一行的： conda install -c conda-forge poppler 才是终级解决办法。。。。。。至此，nice
