I am rather new to Linux (Ubuntu) and installing (Python) packages. I'm having trouble with mkvirtualenv and can not solve it:
~$ mkvirtualenv mysite70

Did I install something wrong?
This is likely a permissions error with your current logged in user on the Linux machine.
Try
sudo mkvirtualenv mysite70
This will often prompt for the password of the root user.
If that does not work, you may want to look at the article below:
http://noelusion.com/2013/Fixing-the-mysterious-virtualenv-error-IOError-invalid-Python-installation/
But note, that the article is a hack on a fairly specific instance.
I think I messed up the installation. I reinstalled Ubuntu, virtualenv etc. It works fine now.
Make sure your username has accents or special characters. If yes, change directory creating environments creating an environment variable WORKON_HOME with value equal to the new path. Ex .: C:\Envs

I am new to django. I wanted to create my first sample project so I followed all the usual ways(as in youtube) and installed python 3.4,pip,django etc. When the environment was set I typed the below command in windows powershell
django-admin startproject mysiteone
and got the below syntax error message(See last para)
My system uses Windows 7 OS. I was unable to find even the version of django i had installed. I dont know why.
I gave these codes in powershell:
django-admin startproject mysiteone
python -m django --version
Error message that I got as a result:

i had the same problem and i solved by migration to python >= 3.5 , it's an unpacking problem => https://www.python.org/dev/peps/pep-0448/
I have Django 1.9.7 installed, and its works fine, but every time I open the terminal, I get this message.
If Python could not import the module virtualenvwrapper.hook_loader,
check that virtualenvwrapper has been installed for
VIRTUALENVWRAPPER_PYTHON=/usr/bin/python and that PATH is
set properly.
When I startproject in Django, it works fine. I wonder whether this will cause problems in the future, and how can I fix it?
I speculate that it is causing this problem because I used to use Python 2.7 with Django 1.9.7. I have recently upgrade by python to 2.4, but it seems that my packages for python 2.7 still exist in my computer. However, when I tried removing the python 2.7 packages with pip uninstall python == 2.7, I get this error

I have read that it is not good to uninstall packages using pip because it does uninstall everything, but I am not sure how else to do it, and I am not sure how to fix the module issue either.
I have been using ipython and also a little bit of jupyter for quite some time, some time ago. After not having used it in almost 6 months I wanted to start using it again.
I installed the newest version of jupyter, updated my python 2.7 install, got pip working and installed the necessary packages:
pip install jupyter
pip install notebook
and etc. After having done that I tried to enter an old notebook (written in 2.7) but there was no connection to the kernel. I thought, well wth, why not just update to the newest python 3 version and try that. That resulted in the same problem.
I went ahead and installed anaconda and created two virtual envs, one with python 2.7 and one with python 3.5. Both installed like this:
conda create --name py27 python=2.7 anaconda
conda create --name py35 python=3.5 anaconda
After that I made sure that both venvs had jupyter installed by activating them and trying to install the package. (This was done with py27 and py35 which are the names of the venvs as seen from above commands).
activate py27
conda install jupyter
After that I tried to run:
jupyter notebook
I created a new notebook file to see if I had access to the kernel. However it was made clear that I didn't with the following error:

This was obviously tried on my py35 venv however I get the same error on my py27 venv. I have tried a few things such as running the kernelspec, but none of it to any success.
Someone got a suggestion to what might be wrong?
I had the same problem. You need to create a kernelspec for the jupyter notebook. Follow this link to solve it.
How to start an ipython shell(not notebook) within a conda or virtualenv
I was using the command virtualenv --no-site-packages django-env but I encountered the following error
Traceback (most recent call last):

I am using Ubuntu 14.04 and Python 2.7.6
I am unable to figure what is causing the error.
Regarding ownership of the development folder:
I had a similar error when running virtualenv on a virtualbox mounted drive. Switching over to a directory on the virtual machine ran fine.
All the best.
By default, VirtualBox will forbid creating symlinks in mounted shared folders due to the security reasons.
You can however, enable it yourself manually using the following command.
VBoxManage setextradata VM_NAME VBoxInternal2/SharedFoldersEnableSymlinksCreate/SHARE_NAME 1
After that virtual environment should be bootstrapped correctly. Do not forget to shutdown the VM for this setting to be picked up.
You can refer to this VirtualBox's ticket for more details: https://www.virtualbox.org/ticket/10085.
I had a similar error when running virtualenv on a mounted drive. For me "--always-copy" option resolved the issue.
If you're using venv module (like you're supposed to nowadays), create the virtual environment in some nonshared folder. The stupid feature of that module is even if you specify --copies flag, it still tries to create symlinks, but between two folders in the same directory.
Create the virutal environment in a non-shared folder between your vm and host, remove the symlink and duplicate the lib folder via copy or another command.
On your home try these commands
1.sudo easy_install virtualenv
2.mkdir virt_env
3.virtualenv virt_env/test1
4.source test1/bin/activate
5.pip install django==1.7.4
after that
django-admin.py startproject project_name
I 'm not able to install python packages from both pip and easy_install. There's some absurd kind of error that keeps popping up. Kindly help to rectify it.
I get the same errors while using python setup.py install.

Find get_entry_map(self, group=None): into python\Lib\sitepackages\pkg_resources\__init__.py. Insert after print self.egg_info
Run python setup.py and look to the last printed - broken package.
Remember it, later to install again. Delete the folder of broken
package and folder broken_package-version.dist-info. Run again paragraph 2, until the error disappears.
Remove changes from paragraph 1.
python setup.py install 'broken_package'
This error happened to me installing any package. My solution was going to my file explorer, typing in the path bar %appdata%, going to the Python folder, and deleting everything inside.
I found the same problem to be caused by a misfometted entry_points.txt file in one instelled egg of mine.
It can be quite hard to track down which one is if there are many.
I managed to find that little ba##!"d by creating and run setup.py for a dummy package:
setup.py
from setuptools import setup, find_packages
setup(
name = "IWillFindYou",
version = "0.1",
packages = find_packages()
)
run this in debug mode would point to this line in pkg_resources.py
def parse_map(cls, data, dist=None):
[...]
raise ValueError("Entry points must be listed in groups")
if you go back to the stack trace, you will see that parse_map is called here:
def get_entry_map(self, group=None):
[...]
ep_map = self._ep_map = EntryPoint.parse_map(
self._get_metadata('entry_points.txt'), self
)
evaluating self.egg_info will point up your evil egg so you can give a look to the entry_points.txt file.
If you are not handy with debugger, you may try to place print self.egg_info in get_entry_map and look to the last guy printed.
My Resolution Approach
Platform: windows 10, ConEmu-Maximus5
Delete virtual environment automatically created by poetry install command.
windows users can find the virtual environment folder in the path below
C:\Users\YOUR_PC_USERNAME\AppData\Local\pypoetry\Cache\virtualenvs
(don't know of linux path)
close terminal / command prompt
open terminal / command prompt and navigate to project folder
re run poetry install
I hope it helps...
How i encountered the error
It was my first time using poetry, while running poetry install, the process got interrupted. running the command again popped out the error.
Could be a problem with distribute. I'd recommend re-installing Python.
