Exception Error when Installing NumPy with pip - python

I have been trying to install NumPy and have been have a brutal time with it. I keep getting an exception error no matter what I try. I used the command
$pip install numpy
but it threw this error
Exception:

Just to check, I used import in Python to see if it got anything, it also threw an error though. I have no idea what is going on.
$pip install scipy
gave me no problems. Any help is appreciated! I can't seem to find anything on how to fix this.
Thanks!

Homebrew tries to leave /usr/local writable, so you don't need sudo. See the FAQ for details.
However, if you accidentally use sudo once—or if some other installer you run installs stuff into /usr/local that doesn't realize you wanted it Homebrew-style—then you'll start getting errors, when your Homebrew stuff attempt to modify files that were saved with sudo.
There's a particular problem if you try to use both Apple's pre-installed Python 2.7 and a Homebrew Python 2.7: they both want to install scripts to /usr/local/bin, man pages to /usr/local/man, etc. And Apple's wants to use sudo.
So, most likely, you did a sudo pip install nose for Apple's Python in the past, and now pip install nose for Homebrew's Python is trying to overwrite its files and doesn't have permissions to do so. (Or maybe not nose itself, but something else that requires nose without you realizing it.)
Using sudo with the Homebrew Python will just make the problem worse; don't do that.
The right solution is to either:
Not use a third-party Python 2.7, Homebrew or otherwise, and just stick with Apple's (or upgrade to Python 3; then there's usually no conflict with Apple's 2.7…), or
Never touch Apple's Python 2.7, and only use the other one.
But at this point, you've already screwed things up, and I doubt you want to reinstall your OS from scratch, right?
You can fix things by brew uninstall python for the former, or by uninstalling everything you installed with Apple's Python for the latter. (You can't uninstall Apple's Python; that would break the OS, and the next OS update would just undo it anyway…) And then, either way, you'll probably want to reinstall every package you need for whichever Python you chose to go with, to be safe.
Or, for a quick&dirty solution, every time you get an error like this, you can either delete the conflicting file (sudo rm /usr/local/man/man1/nosetests.1) or make it overwritable (sudo chmod a+w /usr/local/man/man1/nosetests.1); then, your pip will work. Until the next error, which you can fix the same way.

Just run cmd as Admin it worked for me.

Sometimes, the Extras problem I'm going to describe does not affect venvs. Sometimes it does, but if using virtualenv is at all an option, you should try that before doing anything else.
So, let's assume you either can't do that, or you tried it and this is one of the cases where it doesn't actually help.
First, let me say that all of the following is terrible, terrible advice for any purpose except installing new versions of packages that Apple pre-installed in Extras with Apple's Python 2.7 in OS X 10.7-10.13. Anyone reading this who does not have exactly that problem, stop reading now.
Apple's system version of Python 2.7 comes with a nifty set of third-party packages preinstalled in:
/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/
Rather than try to keep these packages up to date, they designed things so that you can easily shadow them with a newer version in your site-packages directory. Which wasn't a terrible idea.
Unfortunately, they stopped doing any serious maintenance on this a few versions of OS X back, but didn't stop shipping it. In particular, they never updated it to work with setuptools and pip, and if you install pip properly (using the get-pip.py script instead of easy_install), shadowing installs will basically never work.
If your pre-installed easy_install is still working, it should still work to install shadowing packages. Do not use it for anything else, but for this specific purpose, it's the right tool. But it doesn't work for every package on every OS X version, so it's a bit of trial and error. You may want to back up Extras and site-packages first just in case.
The way to test it (assuming easy_install succeeds, of course—if it fails with a slew of errors, it obviously didn't work… and it's time to restore your backups) is to start Python, import six, and look at six.__version__ or six.__file__. If it's the new version in site-packages, you win.
If that doesn't work, there's a hacky workaround that may solve your problem: Temporarily move the file Extras/lib/python/six-1.4.1-py2.7.egg-info somewhere else, then see if pip install six successfully installs into your normal site-packages. If so, restore the egg-info file, and test the shadowing again.
If that still didn't work… well, you can install manually, but I think at this point, the pain of having two Python 2.7 installations in parallel is less than the pain of managing the one you have, so I'd consider installing another one (python.org, Anaconda, or Homebrew) and being careful to never touch the Apple one again (virtualenv can help with this).

Permission error with pip Python 3

I am using Python 3 on Mac OS X. Everything was perfect, I used to install packages like this:
pip install somePackage
But IDLE stopped working so I had to re-install it. After that, when I ran pip, I got pip is not defined so I had to install pip. Now, every time I try to install a package using pip, I get this error:

My pip version is :
pip 9.0.1 from /Library/Python/2.7/site-packages/pip-9.0.1-py2.7.egg (python 2.7)
I am using Mac 10.12.6
How can I fix this?
The permission error you're seeing is due to the fact that your site-packages directory (where pip is trying to install to) is protected and owned by an administrator.
Where is the site packages directory
It depends on your Python distribution. That's why I asked for you to include the output of the $ which python command (from the command line), and the >>> import site; site.getsitepackages() command (from Python). These will help you figure out where your site packages directory is. Also, running pip -v will print the directory to which pip is trying to install.
It is important to note that Macs come with a system version of Python. You should not install any packages accessible to this system version of Python, because it is used by the system and you can potentially interfere with its normal workings and/or install malicious versions of packages that will do bad things when the system uses that Python (e.g., if someone made a nasty egg and called it "os" and put it in the site-packages directory for your system Python, then the next time the system python version ran "import os" it would import the nasty egg.)
Why overriding with sudo pip install is not a good solution
While running your pip install command as sudo would probably solve the problem, this is a short-term fix that is very bad for the reasons mentioned in my comment in #Nenand's answer - running pip install X downloads the egg for X from the internet, and runs python setup.py build && python setup.py install on whatever happens to be in the setup.py. While it's easy to be lulled into complacency because, hey, it works!, it's also naive to trust strangers on the internet (and let's face it, the people who make pip packages are strangers to you).
EDIT: I didn't even think of this, but there is also the potential that you mis-type a library, or guess the wrong name, and end up with one you REALLY didn't want (typosquatting). See this BleepingComputer article on typosquatting pip packages.
The proper solution
The proper solution is to figure out why your site-packages directory is protected, and either fix its permissions, or change the site-packages directory pip is using.
I suspect the reason you're seeing this permissions error is that pip is trying to install to the system Python's site-packages directory, which is owned by root for a good reason. The system Python is located at /usr/bin/ and its site-packages directory is located at the following directories:
'/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages'
'/System/Library/Frameworks/Python.framework/Versions/2.7/lib/site-python'
'/Library/Python/2.7/site-packages'
My advice, in this case, is to install Python using Homebrew, Python.org, or Canopy, which will keep your snakes in separate cages and will leave the system Python alone. On my system, python is the system python, python2 is Python version 2, and python3 is Python version 3. This also makes it more clear which version I'm using. I also do not have a pip command - not on my path - so I can't accidentally install something to my system Python. I have to explicitly call pip2 or pip3. Using Homebrew Python will do all of this for you, so that's my most-favored recommendation of the many Python distributions available.

Evens-MacBook-Pro:~ even$
Your normal user cannot install to the system-wide Python package directory. Instead of using sudo, install the package locally for your user account:
pip install --user pelican
That error occured because you don't have permission to write on that system directory. Hence the OSError: [Errno 13] Permission denied.
If you want to install it system wide, you have to run pip with superuser rights in order to gain permission:
sudo pip install pelican
Although, that wouldn't be necessary -- nor a good practice --, for instance, if you are installing inside a virtualenv.
Another possibility, as referred in this answer pointed out by #pherris, is to append the --user flag to the pip command. This would install the package only to the current user:
pip install pelican --user
Modifying the system-level installation of Python (or Ruby, or Perl...) can turn into a mess, and I have had my work there trashed in the past by system updates. Apple doesn't really guarantee your local changes will be preserved after an OS update.
You are likely better off installing your own versions using something like Homebrew, which installs into /usr/local.
Homebrew has Python 2.x and 3.x available (and they can co-exist very well). It keeps up with new releases better than Apple does. Homebrew also has many other Unix things that you may or may not find useful.
After installing Homebrew, installing Python is simple:
brew install python
brew install python3
Make sure /usr/local/bin is early in your $PATH. It also provides you with pip and pip3 to install Python package for both 2.x and 3.x.

How can i get easy_install to actually work?
I postet a similar question here, where (thanks to #J.F. Sebastian) I found a workaround to install those packages without fabric. But now I do want to know, how to actually solve the problem I'm having with easy_install.
Download and install MinGW - Minimalist GNU for Windows.
To making some Unix commands accessible from the windows console, set in your env variables:
C:\MinGW\bin;C:\MinGW\mingw32\bin;C:\MinGW\msys\1.0\bin;C:\MinGW\msys\1.0\sbin
.
Alternatively, from the console:
PATH=%PATH%;C:\MinGW\bin;C:\MinGW\mingw32\bin;C:\MinGW\msys\1.0\bin;C:\MinGW\msys\1.0\sbin
Log in as the administrator of your machine. chmod refers to permissions for accessing directories, and in this case, I have a feeling python is complaining about Windows 7's UAC (user account control). Creating directories in C:\ requires elevated permissions in Windows.
If there's something obvious happening at line 269, you could just edit the script to take out the offending line.
If not, you could install all of the dependencies, and manually install Fabric.
Also, consider using virtualenv and pip.
I can see that you are on a Python 2.x. Thus, I will suggest the method that worked for me.
Download the Pycrypto installer from : Here.
Then do the usual steps. Select the Lib/Site-packages in which you want to install it, I had two Python installations (Python 2 and 3, thus I selected Python 2/Lib/Site-packages).
Go till the end.
After successful installation, open the IDLE and type:
from Crypto.Hash import SHA256
If it works without any error, you are good to go.
Cheers.
Note : I am on a windows 8 machine.

Python Virtualenv: creating python2.5 environment on ubuntu 10.04

when I try to create a virtualenv that uses python2.5 I get the following error:
File "/usr/local/lib/python2.6/dist-packages/virtualenv.py", line 1489, in <module>main()

return os.path.join(lib_dir, "config" + (sys.pydebug and "_d" or ""), "Makefile")
AttributeError: 'module' object has no attribute 'pydebug'
I get this error by doing this command:
virtualenv -p python2.5 .
Because Ubuntu10.04 doesn't come with Python2.5 I installed it from:
https://launchpad.net/~fkrull/+archive/deadsnakes
First I thought that I should installed virtualenv for Python2.5 also but that doesn't seem to work either. If I try to create a virtualenv with the following command:
sudo Python2.5 /usr/lib/python2.5/site-packages/virtualenv.py .
I end up getting the same error. I am kinda new to Ubuntu and Python and there are stil a few blank spot. Like if you have two version of Python, for Python2.6 I can just do virtualenv . But I guess to use the 2.5 one I have to call it directly like I did in the sudo command above?
Or is it completely wrong and all virtualenvs are the same and can be used with different Python versions?
Anyway my main question is how I can fix the error so I can setup a virtualenv using Python2.5. Any extra information is appreciated.
I had some other Python 2.5 installed. I forgot the name but something like Python 2.5 minimal and it gave some problems with the deadsnakes install. When I uninstall it everything started working fine.
You don't need two virtualenvs installed. You can tell virtualenv which python to use by using the --python argument as follows:
virtualenv --python=python2.5 <my-venv>
I was able to get this going in Ubuntu 10.04 Lucid Lynx (which comes with Python 2.6 installed by default) like so:
Install Python 2.5 using the repository at https://launchpad.net/~fkrull/+archive/deadsnakes.
If you don't know how to do this:
1a. Edit /etc/apt/sources.list by adding the line: deb http://ppa.launchpad.net/fkrull/deadsnakes/ubuntu lucid main
1b. Run 'sudo apt-get update'.
1c. Run 'sudo apt-get install python2.5'.
1d. Verify that python2.5 is on the PATH by running 'which python2.5'.
Run 'virtualenv -p python2.5 ENV' (where ENV is whatever you want to call your environment directory).
You can then do the usual stuff like '. env/bin/activate' and so on. This method worked just fine for me, but let me know if run into problems with your setup.
sudo easy_install-2.5 virtualenv
will give you a python 2.5-specific virtualenv. Invoke it using virtualenv-2.5. You may need to apt-get install setuptools first if you don't have easy_install.
