When I try to run
sudo virtualenv -p /Library/Frameworks/Python.framework/Versions/7.3/Resources/Python.app/Contents/MacOS
It shows the following error:
Running virtualenv with interpreter

I tried removing my pip.log file as this answer advised me to, but the problem persists. Any solutions?
Edit:
I should explain that I'm trying to create a virtualenv located at the <path name> because I want to install a package with pip for that version of Python.

While trying to run a python script on EC2 (running ubuntu), I'm getting this error:
Traceback (most recent call last):
File "128d.py", line 9, in <module>

File "/usr/lib/python3.6/subprocess.py", line 267, in call

raise child_exception_type(errno_num, err_msg, err_filename)
FileNotFoundError: [Errno 2] No such file or directory: 'python': 'python'
All the dependencies are installed. I've tested the script on my home machine (Windows 10), and it works just fine. I can see that something is wrong with python installed on the EC2 machine, probably. But I didn't manage to find an answer on the web.
I've fixed the problem.
Turns out, I had my python installed in a folder that was named python3. So, when the suprocess.py file tried to find python in path, it wasn't there.
I've renamed python3 in /usr/bin/ to python and the problem is fixed.
P.S. However, keep in mind, that it might raise some other issues. When I tried to aws s3 cp, it was looking for python3 instead. Maybe adding another copy of that folder as python3 would help.
i have installed the tasseract using
pip install pytesseract
whenever i tried to run this piece of code
from PIL import Image
import pytesseract
im = Image.open('hasan1.jpg')
print (pytesseract.image_to_string(im))
I got these errors.

I believe PyTesseract requires you to have the tesseract library installed on your system - PyTesseract is trying to run the command-line interface but it can't find it presumably because you have only installed the python bindings.
If you are on an Ubuntu/Debian-based system, you can try:
sudo apt-get install tesseract-ocr
You can check the Tesseract installation docs for more info: https://github.com/tesseract-ocr/tesseract/wiki
I'm trying to create a virtualenv, but I'm getting a Permission denied error. I'm using the following code
python2.7 -m virtualenv -p `which python2.7` test
Which gives this error message:

To debug the error in os.py, I've added a print statement, it looks like the script tries to make the directories /lib/python2.7 and /lib/python2.7/site-packages. I don't understand why virtualenv tries to create these directories there and not in my current directory.
I've installed virtualenv without sudo, so I don't expect it to create directories in a path that is owned by root.
In the end only the python executable is copied to the 'test' directory, but not setuptools, pip and wheels.
Is there a way to avoid virtualenv from accessing root owned directories?
--update--
using python3 with venv works fine, the problem is with virtualenv specifically.
Executing virtualenv from my home directory give no error.
Looks like you're trying to create the virtualenv test within /lib/python2.7/site-packages, which, by all rights, you shouldn't have write access to.
Try running cd ~ first, to create the venv in your home directory.
I had the same mysterious error; it turns out I had forgotten a setting in my $HOME/.pip/pip.conf that changed the prefix.
I created a virtualenv via command venv. Then I installed tesseract via command brew install tesseract. But I can use it only on actual env, when I use it on virtualenv, an error No such file or directory: 'tesseract' is thrown:

Does anyone have an idea ?
Already tried :
chmod u+x doxybuild.py
sudo chmod 775 /usr/lib/python2.7/subprocess.py
sudo chown $USER /usr/lib/python2.7/subprocess.py
But nothing resolved my problem.
Ok, problem solved :
$> cd jsoncpp/doc
$> cat readme.txt
The documentation is generated using doxygen (http://www.doxygen.org).
$> sudo apt-get install doxygen
...
OK
$> python doxybuild.py --doxygen=$(which doxygen) --open --with-dot
...
ok
Just install doxygen and building the documentation will work.
