OS: Debian GNU/Linux v9
System: Python 3.4.2
Ran command: sudo apt-get install build-essential python3-dev python3-lxml python3-pip python3-setuptools python3-wheel python3-lxml libssl-dev libffi-dev
I can do the following: python3 then import lxml
And it works! :)
I make a virtual environment, pip3 install some stuff, and type pip3 list

Then I type: pip3 install lxml and get this:
cc -I/usr/include/libxml2 -c /tmp/xmlXPathInithmyjgqp8.c -o tmp/xmlXPathInithmyjgqp8.o
/tmp/xmlXPathInithmyjgqp8.c:1:26: fatal error: libxml/xpath.h: No such file or directory

Could not find function xmlCheckVersion in library libxml2. Is libxml2 installed?

error: command 'arm-linux-gnueabihf-gcc' failed with exit status 1
So it seems lxml can install on system, but not in a virtual environment. What am I doing wrong, and why is this?

I run pip freeze --user | xargs pip uninstall -y to remove all and I get this error:

If you're sure you really need to uninstall packages installed under /usr/local/ use superuser privileges:
pip freeze --user | xargs sudo pip uninstall -y
I am trying install scipy in FreeBSD 13. I have built python 3.10 on FreebSD 13 and managed to install pandas, matplotlib and numpy on a virtual environment which has python 3.10. However, when I try to install sklearn or scipy I get an error saying scipy could not be installed.
Here it is below for when doing pip install scipy. I get the same error more or less when trying to install sklearn.
ERROR: Failed building wheel for scipy

Reuse system package
# install system-wide version in site-packages
doas pkg install py38-scipy-1.8.0
# create a virtualenv with site-packages included
python -m venv --system-site-packages .venv
Drawback is you'll get all packages from site-packages, however you can tackle that by
doas pkg install py38-scipy-1.8.0
python -m venv .venv
YOUR_PYTHON_VERSION= SET IT HERE
ln -s $(python -c 'import lxml, os.path; print(os.path.dirname(lxml.__file__)') ./.venv/lib/$YOUR_PYTHON_VERSION/site-packages

Haven't figured out it yet, but maybe someone else will, so putting here 2 links which might be helpful

Have you tried to install scipy from freebsd ports? The freebsd ports contain patches to make the code compile on FreeBSD.

I installed python-3.5 on Ubuntu 16.04.3 and planned to have python-3.6 as well with conda environment. For the conda enviornment with python-3.6, I named it as py36. However, though I installed package a package in (py36) environment, python complained that there was no such module. Why was python confused?
Below is the code I ran:
$conda create --name py36 python=3.6
$ source activate py36
(py36) xxx#Alienware:~/crawler$ conda install --name py36 -c anaconda cached-pro
(py36) xxx#Alienware:~/crawler$ conda list -n py36

I am having some problems installing lxml 3.6.4 in python 3.6 64bit using Pycharm and PIP.
pip install lxml==3.6.4
ERROR: b"'xslt-config' is not recognized as an internal or external command,\r\noperable program or batch file.\r\n"
** make sure the development packages of libxml2 and libxslt are installed **
When installing libxml
pip install libxml2-dev
I get the following error:

No matching distribution found for libxml2-dev
When running libxslt

The ultimate goal is to install pyiso on Pycharm.
My specs - Windows 7 - 64
Python 3.6
On Linux, with the typo corrected, #pguardiario's comment above fixed this for me.
sudo apt-get install libxml2-dev libxslt-dev
Then:
conda install lxml
Or:
pip install lxml
