I'm trying to import dateutil in pypy, which I've got the following error. Importing dateutil in python2.7 didn't return an error

>>>> import dateutil
Traceback (most recent call last):

ImportError: No module named dateutil
I'm not sure if this is related but dateutil is found in
/usr/lib/python2.7/site-packages
But not found in
/usr/lib64/python2.7/site-packages
pypy on the server is located in
/opt/pypy-7.2.0-linux_x86_64-portable
I tried uninstalling dateutil and reinstalling dateutil using pip, but pypy can't seem to find it.
Would appreciate any help. Thank you in advance!!!
You might be using the wrong pip. When you call pip install ... you will find whichever pip is first on your $PATH, which may not be the one you need. I try to use path/to/pypy -mpip install ... which will ensure you are using the correct one

I'm trying to work with psycopg2 natively on Mac. It installs fine, with no errors at least, but when i import it get an error message.
I've seen dozens of threads with similar issues and solutions that vary massively and just seem excessive for such a common module.
can anyone help?

I can see some copies floating round from different applications.
I'm assuming i could copy one of these. The above message tells me what is referencing this file, but they do not tell me where they expect to find it. If i knew where it should go i would try this.
bash-3.2# find . -name "libssl.1.0.0.dylib"
./Library/Application Support/Fitbit Connect/libssl.1.0.0.dylib
./Library/PostgreSQL/9.5/lib/libssl.1.0.0.dylib

Thanks guys.
#maxymoo I went with your suggestion. I have installed anaconda2. The install updated my path to include /anaconda/bin.
Then using the navigator I installed pyscopg2. Now I am able to use this in the shebang and my scripts execute fine and i'm able to import this module.

I have python installed in two locations, in os default it's 2.6.6 and in /usr/local/bin/python2.7 has 2.7.
I have installed cairo (cairo-1.12.18) via source using configure/make/make install, but it appears to have installed under python 2.6.6. How do I install it for python2.7?

Thank you.
Be sure to install it using python 2.7 and not python 2.6 (run make and make install using python 2.7). I assume you use Linux OS so your default Python is 2.7, you can change your default Python but it's not recommended due to several reasons. Please look at this StackOverflow question and answers for more informations:
Two versions of python on linux. how to make 2.7 the default
I used to have pypy verion 1.9. I could do the following to import numpypy:

And now for something completely different: ``translating pypy with cpython is
soooooo slow''
>>>> import numpypy
Recently I updated my os and installed pypy Version 2.2 now I am not able to import numpypy
>>>> import numpypy
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named numpypy
What could be the issue? I know numpy is not fully supported, but I have many scripts that use the limited functionality of numpypy in pypy.
See the third bullet here: http://doc.pypy.org/en/latest/release-2.2.0.html#highlights

I've installed Python 3.3 alongside Python 2.75 on my Ubuntu machine. The problem is that easy_install gets packages for the default, 2.75 version only, e.g:
easy_install pymongo
$ python
Python 2.7.4 (default, Apr 19 2013, 18:28:01)
[GCC 4.7.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import pymongo
>>>
But:
$ python3.3
Python 3.3.1 (default, Apr 17 2013, 22:30:32)
[GCC 4.7.3] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import pymongo
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named 'pymongo'
How can I install PyPi packages for the Python 3.3 installation?
You need easy_install3. In apt-get you get it by
apt-get install python3-setuptools
