First, I installed lxml without using pip (Python 2.7.2 on Mac OS 10.6.8). Then, I read this post and I installed it again using pip (sudo pip install lxml). I still had a problem:
I can import lxml (import lxml) but I cannot use from lxml import etree. I have this error message:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: dlopen(/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/lxml-2.3.3-py2.7-macosx-10.6-intel.egg/lxml/etree.so, 2): Symbol not found: _htmlParseChunk

Then, I tried to install lxml from source following these instructions, and I have this error message:

Finally, I followed the second advise of this answer and I used the command line sudo STATIC_DEPS=true /usr/bin/easy_install-2.7 lxml. It installed lxml on the Apple-supplied system Python 2.7, and not on the version I'm currently using. The positive point: if I run the Apple-Python, I can from lxml import etree.
Negative point: I still don't know how to install lxml on another version of python. Any idea?
I'm currently using /Library/Frameworks/Python.framework/Versions/2.7/bin/python.
You need to install a separate easy_install for the version of Python you are using. See the answer here for more details. Then you can run the easy_install command using it:
STATIC_DEPS=true easy_install-2.7 lxml
UPDATE: From your comments, you now are reporting a permission error showing yet another Python path, one that appears to be a MacPorts-installed Python: /opt/local/Library/Frameworks. You need to figure out which Python you want to use. If, in fact, you want to use the MacPorts one, then simply install the MacPorts-provided lxml port. That's the easiest solution.
$ sudo port selfupdate
$ sudo port install py27-lxml
Otherwise, you need to install easy_install with the other (python.org?) Python 2.7.2. I would recommend to use Distribute, the more modern fork of `setuptools' and you need to ensure you are using the right Python:
$ curl -O http://python-distribute.org/distribute_setup.py
$ export PATH="/Library/Frameworks/Python.framework/Versions/2.7/bin:${PATH}"
$ which python2.7 # should be in the path above
$ python2.7 distribute_setup.py
$ STATIC_DEPS=true easy_install-2.7 lxml

A few days ago I wanted to run dnf but I received the following error
Traceback (most recent call last):
File "/usr/bin/dnf", line 57, in <module>
from dnf.cli import main
ModuleNotFoundError: No module named 'dnf'
Thus I tried to run yum and I received something similar:
Traceback (most recent call last):
File "/usr/bin/yum", line 57, in <module>
from dnf.cli import main
ModuleNotFoundError: No module named 'dnf'
I do not know what happened and I hope someone can help me find the problem and solve it. The only thing I know is that it might be related to the fact that a few days before I installed tensorflow in python using conda. Although it seems conda does not work now because I get this:
Traceback (most recent call last):

I am using fedora 29
Thanks!
I had the same problem, but after all trial and error the only thing actually worked was:
rpm -qa python3
This will announce your python3 rpm package.
I've searched and downloaded it from web
Go to the downloaded directory like:
sudo rpm -e --nodeps python3-3.7.2-4.fc29.x86_64(my python3 rpm package)
sudo rpm -i python3-3.7.2-4.fc29.x86_64.rpm
I tried many other methods so this'll not be a only factor that resolve that problem.
Hello,
i have just been through this in Fedora 31 and do not exactly know what was the cause that led to this same issue, it must have been some package managing over another context that came up only on my next need to use DNF.
I am assuming that before this stated error:
Traceback (most recent call last):
File "/usr/bin/dnf", line 57, in
from dnf.cli import main
ModuleNotFoundError: No module named 'dnf'
You were having this message when executing dnf:
/usr/local/lib/python3.7/site-packages/dnf.py:15: UserWarning: The DNF Python API is not currently available via PyPI.
Please install it with your distro package manager (typically called
'python2-dnf' or 'python3-dnf'), and ensure that any virtual environments
needing the API are configured to be able to see the system site packages
directory.
After some hours researching and trying to install each DNF rpm dependency of the DNF rpm itself(https://pkgs.org/download/dnf) i felt as an intuition that maybe i should try to remove(mv sure)
/usr/local/lib/python3.7/
which had just one folder in it named site-packages
It worked!
Thank you.
I have a friend who met the same problem.
He tried to uninstall python3.7 in linux server by some amazing cmd rpm -qa|grep python3|xargs rpm -ev --allmatches --nodeps and whereis python3 |xargs rm -frv.
This caused the yum and dnf to break.
I changed the /usr/bin/yum to use a local python3.8 version, but it caused ModuleNotFoundError: No module named 'dnf' at last, and didn't solved it.
It is not a good way to download many rpm packages on the Internet. And I can't use yum either. But I have another same linux OS server, so I've tried to copy the correlation files about python3.7.
$ rpm -ql python3-3.7.0-9.h4.eulerosv2r8.aarch64> py.log
$ while read -r line;do dirname $line |xargs -I {} ssh root#$remoteip "mkdir -p {}" ;scp $line root#$remoteip:$line ;done<py.log
$ rpm -ql python3-libs-3.7.0-9.h4.eulerosv2r8.aarch64 >pylib.log
$ while read -r line;do dirname $line |xargs -I {} ssh root#$remoteip "mkdir -p {}" ;scp $line root#$remoteip:$line ;done<pylib.log
scp -r /usr/lib/python3.7/site-packages root#$remoteip:/usr/lib/python3.7/
I recovered yum this way.
I had the same issue.
For me the solution was to simply uninstall the python3 dnf package (including from all virtualenvs) that I had obviously installed somewhen.
pip uninstall dnf
had the same error.
my fix ->
cd into /usr/bin. has many python files...
latest python (3.11) has pytest, python3 -> python3.11 (symlink), python3.11, python3.11-config, python3.11-x86_64-config, python -> python3
had been using 3.9, not familiar with python so much, so changed symlink back to python3->python3.9 after Fedora 36 update changed symlink to 3.11 and installed python3.11. when i changed symlink back to 3.9, this created the error message. When i changed the symlink back to python3->python3.11 the error disappeared and all works fine. DNF is fine etc. did nothing else.
since all the other python files were pointing to the 3.11 versions, introduction of the symlink to 3.9 must have blown the fuse...
I am using windows 8 and python 3.6.1 I've done the following command in my cmd:
pip install cryptoshop
However, when I run the following python code:
from cryptoshop import encryptfile
from cryptoshop import decryptfile
result1 = encryptfile(filename="test", passphrase="mypassphrase", algo="srp")
print(result1)
result2 = decryptfile(filename="test.cryptoshop", passphrase="mypassphrase")

import botan
ModuleNotFoundError: No module named 'botan'
Now, I obviously know that you must install botan into python in order to use it. However, this is where I am running into an issue. I've downloaded Botan from this link as instructed:
https://github.com/randombit/botan
And then I've followed these instructions in an attempt to install Botan:
./configure.py [--prefix=/some/directory]
make
make install
However, when I type make into the command line I get an error saying there is no such command. And then when I go to run my above Python code I still get the no module Botan error. So obviously I am doing something run. How can I properly install Botan into my Python 3.6 directories so that I can use cryptoshop.
I've also attempted to do pip install Botan, as that is how I've installed so many other python libraries but that has been unsuccessful as well.
make is a linux command
According to the botan website you can use nmake as a replacement on windows ( http://wiki.c2.com/?UsingNmake ) :
On Windows
You need to have a copy of Python installed, and have both Python and
your chosen compiler in your path. Open a command shell (or the SDK
shell), and run:
$ python configure.py --cc=msvc (or --cc=gcc for MinGW) [--cpu=CPU]
$ nmake
$ botan-test.exe
$ nmake install
Botan supports the nmake replacement Jom which enables you to run
multiple build jobs in parallel.
source : https://botan.randombit.net/manual/building.html
For completeness, here's how I made it work on a Mac
Assuming you have brew installed.
brew install botan
You may need to install other functionality first:
brew install gmp
brew install mpfr
brew install mpc
Find out where botan got installed with brew info botan.
My location is /usr/local/Cellar/botan/2.6.0
In that folder, you'll find lib/python2.7/site-packages, copy the contents of this folder into your Python's installation site-packages folder.
Note 1: At the time of this writing, only python 2.7 seems to be supported, but I'm using python 3.6 and everything seems to be working.
Note 2: If the file is called botan2.py, you may need to rename it to botan.py in your python's site-packages folder.
I've looked at quite a lot of related questions here - no help for me. I need to repair easy_install, so that I can update distribute to a version >=0.6.28, so that I can update python matplotlib using pip and not yum.
In the process of trying to update python matplotlib from 0.99 (the default with Centos64) to 1.4.x, I got into this trouble:
pip install --upgrade matplotlib tells me this:
Complete output from command python setup.py egg_info:
The required version of distribute (>=0.6.28) is not available,
and can't be installed while this script is running. Please
install a more recent version first, using
'easy_install -U distribute'.
(Currently using distribute 0.6.10 (/usr/lib/python2.6/site-packages))
So I followed the suggestion and saw that some 0.7.x version of distribute was installed (so it seemed). Re-ran the pip command and got the exact same complaint.
Trouble with easy_install?
It was either now, or maybe after performing yum remove, then install python-setuptools that I discovered easy_install is thoroughly broken. Now when I try to run easy_install, I get this stacktrace:
Traceback (most recent call last):
File "/usr/local/bin/easy_install", line 9, in <module>
load_entry_point('distribute', 'console_scripts', 'easy_install')()
File "/usr/local/lib/python3.3/site-packages/setuptools-18.2-py3.3.egg/pkg_resources/__init__.py", line 558, in load_entry_point

raise ImportError("Entry point %r not found" % ((group, name),))
ImportError: Entry point ('console_scripts', 'easy_install') not found
Look at that - why is it referring to python3.3? I don't think I've got that installed. My default python is 2.6.6.
Any ideas? TIA.
Fixed it. The python3.3 bit was my clue. I found the python script for easy_install, in /usr/local/bin. The very first line designated /usr/bin/python3.3 to execute the script. Changed to 2.6 and then was good to go.
In the end I was not able to upgrade matplotlib from 0.99 to 1.4.3, because I could not upgrade basemap from 0.99 and some conflicts arose. Rather than punish myself with trying to build from source, I think I should simply upgrade my entire VM to Centos7 and I will then have much newer matplotlib.
I have installed the Emacs package jedi-emacs using M-x package install
and the following Python packages:
Jedi
EPC
argparse
using:
pip install --install-option="--prefix=~/.my_python_packages/" jedi
pip install --install-option="--prefix=/.my_python_packages/" epc
pip install --install-option="--prefix=/.my_python_packages/" argparse
since I do not have root priviledges.
When I open a Python file, I get the following error in the minibuffer, no matter where I place the cursor:
deferred error : (error Server may raise an error : Traceback (most recent call last):
File "/home/avazquez/.emacs.d/elpa/jedi-20130119.830/jediepcserver.py", line 261, in <module>
)
What could be causing it?
This is with Emacs 24.2.1
I found the solution to my problem. I did not have PYTHONPATH set up correctly (it should include the corresponding paths for /path/to/custom-packages).
For more info on this issue see the corresponding ticket in the package repository for emacs-jedi.
Easy_install and Pip doesn't work anymore on python 2.7, when I try to do:

I've already install both of them (and yes, first deleted them), but no result...
Thanks!
(I tried already this post)
I had this issue where python's distribute package wasn't installed for some reason. After following the instructions on python-distribute, i got it working.
install the distribute package as follows:
$ wget https://web.archive.org/web/20100225231201/http://python-distribute.org/distribute_setup.py
$ python distribute_setup.py
EDIT: http://python-distribute.org/distribute_setup.py no longer works:
hopefully this will resolve your problem with running
$ sudo easy_install
Happy Coding!
If you installed a new version of easy_install through Distribute, the new command may have been installed in another directory, most likely /usr/local/bin/. But the traceback shows you were using /usr/bin/easy_install. Try this:
sudo /usr/local/bin/easy_install ...
Try
sudo easy_install Distribute
and if that exists, but is too old
sudo easy_install -U Distribute
Looks like either Distribute/setuptools (it's old name) is messed up or Python package settings. If either of these do not help, try removing the full Python 2.7 installation and reinstall everything from the scratch.
Possible reasons for the mess is that you have used both sudo easy_install / sudo pip and Linux distribution packages to mix and match system-wide installation packages. You should use virtualenv instead if you use pip/easy_install (no sudo needed)
http://pypi.python.org/pypi/virtualenv
I had a similar problem, but things were working fine as root. In my case, I found that the permissions on the python packages were not readable by the ID I was running the command under.
To correct it, I ran the following command to open the permission for read and execute to all users:
sudo chmod o+rx -R /usr/local/lib/python2.7/dist-packages/*.egg
I had similar issue when trying to install package via pip with python 3.6 on windows. (pip is supposed to work out of the box with this install)
The problem was not running as administrator.
Running cmd as administrator and then installing my package worked:
python -m pip install pylint
I was trying to get pip to work on the 2.7.0 version, but it seems like it doesn't come with the easy_install/pip files (Script folder in main directory), installing 2.7.13 solved the problem for me.
