I am installing packages from requirements.txt
pip install -r requirements.txt

lxml
cssselect
jieba
beautifulsoup
nltk
lxml is the only package failing to install and this leads to everything failing (expected results as pointed out by larsks in the comments). However, after lxml fails pip still runs throu….
