Installing PyQuery Via Pip

I'm attempting to install PyQuery via pip but I'm getting an error I do not understand. The command I used was:

sudo pip install pyquery

I get the output below:

I have a feeling it's something to do with dependencies, but should 'pip' not automatically install dependencies?

回答1:

You have missing dependencies. Try running:

sudo apt-get install libxml2-dev libxslt1-dev python-dev

回答2:

Put following lines in a file called pyquery.sh

#ADD SWAP FOR lxml COMPILATION
fallocate -l 1G /swapfile
chmod 600 /swapfile
mkswap /swapfile
swapon /swapfile

#ACTIVATE ENV
#Comment following line if you don't use virtualenv
#source /home/py3/bin/activate

#INSTALL ALL DEP
add-apt-repository -y ppa:ubuntu-toolchain-r/test
apt-get -y update
apt-get -y install gcc
apt-get -y install g++
apt-get -y install build-essential
apt-get -y install python-dev
apt-get -y install libxml2-dev
apt-get -y install libxslt-dev
apt-get -y install libxslt1-dev
apt-get -y install zlib1g-dev
apt-get -y install python3-setuptools
apt-get -y install python3-lxml
apt-get -y install python3-lxml-dbg
apt-get -y install python3-dev

pip install lxml
pip install pyquery

#REMOVE SWAP
swapoff /swapfile
rm -rf /swapfile

After this run this file by:
