Hi All, The installation of the lxml 3.5.0 is failing on the CentOS 7 (x86_64). The search on the web did not help much. My last hope is your group. I tried with using pip with different arguments: lxml==3.5.0 (.venv) [centos@MyDirectory]$ pip install -r env/requirements where file requirements has only one line: (.venv) [centos@MyDirectory]$ pip install lxml-3.5.0.tar.gz [centos@MyDirectory]$ sudo pip install lxml==3.5.0 [centos@MyDirectory]$ sudo pip install lxml-3.5.0.tar.gz [centos@MyDirectory]$ .venv/bin/pip install lxml-3.5.0.tar.gz [centos@MyDirectory]$ sudo .venv/bin/pip install lxml-3.5.0.tar.gz All the times the first line indicating an error is: " Running setup.py install for lxml ... error" Also I looked to use command "yum info package", but did not find an appropriate .rpm file for lxml-3.5.0. The console outputs of the last attempt with pip is below (actually, they all are almost the same): [centos@MyDirectory]$ sudo .venv/bin/pip install lxml-3.5.0.tar.gz Processing ./lxml-3.5.0.tar.gz Building wheels for collected packages: lxml Running setup.py bdist_wheel for lxml ... error Complete output from command /home/kokone/.virtualenv/bin/python -u -c "import setuptools, tokenize;__file__='/tmp/pip-v7rlpA-build/setup.py';exec (compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" bdist_wheel -d /tmp/tmpNsW741pip-wheel- --python-tag cp27: Building lxml version 3.5.0.
