I have successfully install dogtail 0.7.1.1 on my system but when I try to

I get this error instead

I have used the below command to verify that gconf is available on my system. Have anyone encountered this problem?

2.16.0
pip install gconf should fix it.

Hello I am using mac actually when I searched analytics in finder I removed some folders (I thought they are useless :) after that when I type conda update or such I am getting those errors and further more.
I am keeping exact error:

Python comes with some libraries that are required to preform some basic operation later in python such as update or install libraries. I think you removed those python libraries that are required to update/used in other ....to remove these error you have to add/restore those libraries or reinstall python.
I am having issues launching Jupyter Notebook. I have tried to do it two ways and seem to get errors.
1 - Launching from the Anaconda Prompt using the command jupyter notebook or directly choosing from the Anaconda menu
I get the following:
(base) C:\Users\metni>jupyter notebook
Traceback (most recent call last):

Jupyter notebook format depends on the jsonschema package:
https://pypi.python.org/pypi/jsonschema
Please install it first.
2 - Launching from the command line with the same command
I get the following:
C:\Users\metni>jupyter notebook
Traceback (most recent call last):
File "C:\Users\metni\anaconda3\Scripts\jupyter-notebook-script.py", line 6, in <module>

It seems like this is referring to a package called jsonschema which is not installed apparently, but running a pip install jsonschema does not solve the problem for me...
In the answer above I also have two two commands but they are a bit different
source /opt/anaconda/bin/activate root
and then
jupyter notebook
It seems like you have to go into your anaconda directory then bin, then you can
"activate root"
It also looks like you need to install some other dependencies for jupyter to run. Where is says
Jupyter notebook format depends on the jsonschema package:
https://pypi.python.org/pypi/jsonschema
Please install it first.
So if the above doesn't work try installing the other dependency and try again
Based on this answer from a similar question, I managed to solve the problem by running these two commands:
conda update -n root conda
conda update --all
I thus updated all packages, and the notebook is now launching.
An import error occurs when trying to run jupyter notebook
I'm trying to run jupyter notebook using anaconda (git bash platform), and as I type in jupyter notebook, an import error occurs every time. I tried to lauch it inside an environment, but the same error occured.
$ jupyter notebook

After reinstalling pyzmq (and I tried reinstalling conda too), the following error occurs:

I found a similar issue open on GitHub for zmq. The recommendation by GitHub user harsh23tyagi that seems to work for most is to run the following:
pip uninstall pyzmq
pip install pyzmq
Working with conda env, jupyter notebook worked in (base) env but gave the .libzmq error in (my_env).
To be able to run notebooks from my_env, this worked for me :
pip uninstall pyzmq
pip install pyzmq==20 (no version for pyzmq didn't fix the issue for me)
It seems that updating pyzmq to the latest version fixes this problem for me.
conda install pyzmq=22
I have installed anaconda in mac os sierra. Simple python scripts run fine. However, when I try to run jupyter-notebook it fails.
The error message is following:

I checked the dylib file, but it is there. What's wrong here?
Bhishan:ls /usr/lib/libsqlite3.dylib
/usr/lib/libsqlite3.dylib*
Similar problems:
No module named _sqlite3
But they did not solve my problem.
Your problem is most likely due to several python envirionments.
Check this question.
Also this question maybe relevant.
Also try to see all installed packages with conda.
I have faced the same issue.
For me installing sqlite via brew solved the issue.
brew install sqlite
I am trying to install ns-3 by tarball but when I try to build with following command
./build.py --enable-examples --enable-tests

I know this error is related to python but not able to resolve after doing a lot of Google search.Can anybody help me how to proceed further?
Solved:
After exhausted research I found Python for Linux default setting is UCS2.
I rebuilt Python from source using
./configure --enable-unicode=ucs4
to force compile using UCS4.
Here is the link.
