I have re-installed the Python I used and it doesn't work, I'm in Ubuntu 12.04. Also I have do
grep ravjqpejcnngpig.eqo/re/fgh/ocr . -R -n
under /usr/lib/python2.7 but nothing returned.


Perhaps you have a module named string in your project, and it shadows the library module of the same name.
EDIT: To find out, add this to your script just before the failing import statement:
import string
print string.__file__

WSL: ImportError: cannot import name 'textblob'

I have installed NLTK and TextBlob on Python3 on WSL. No matter what I do, I always obtain the same error. Indeed, trying to install shows that all packages are installed
$ sudo pip3 install -U textblob
The directory '/home/jlchulilla/.cache/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.

I cannot understand where is the problem. Any help would be really appreciated
Edit: When I try to import any other module of NLTK library, same error happens. It's like if previous calling to 'tokenize' would have blocked the module or something

I have a windows machine.
Python version - 3.6.0
Pytest version - 5.2.4
Thanks

The issue I run into in Python2 was that pathlib is a module that was written for Python3 and althought there is a porting for Python 2.7, the porting (1.0.1) is missing the read_text() method.
In your log read_text() is being called from a string, that is the result of the joinpath(), and read_text() is not a method or attribute of a string. That was the whole purpose of pathlib

if _fastmath is not None and not _fastmath.HAVE_DECL_MPZ_POWM_SEC:
AttributeError: 'module' object has no attribute 'HAVE_DECL_MPZ_POWM_SEC'
I have referred some other post that says it "so you'reusing a newer version of PyCrypto with an older version of _fastmath." So I also installed gmp-devel
I am using virtualenv , Centos 6, Python 2.6
please help.

This fixed it for me:
pip install PyCrypto==2.3
I didn't uninstall python-crypto because other packages I needed depended on it. I just ran the pip command above and everything worked :)
