When trying to install Python's sklearn package on Windows 10 using pip I am given an EnvironmentError that tells me there is no such file or directory of a specific file:
ERROR: Could not install packages due to an EnvironmentError: [Errno
2] No such file or directory:
'C:\Users\Rik\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.8_qbz5n2kfra8p0\LocalCache\local-packages\Python38\site-packages\sklearn\datasets\tests\data\openml\292\api-v1-json-data-list-data_name-australian-limit-2-data_version-1-status-deactivated.json.gz'
I have tried reinstalling the following packages numerous times:
scikit-learn
scipy
sklearn
I have also tried downloading the github master folder for sklearn and pasting it into the directory where the installer expects the file to be, and even then when installing with pip it tells me the file is missing.
Furthermore I tried installing it via the github repository by downloading it and running
python setup.py install
But this results in weird Microsoft Visual Studio errors because apparently it is trying to run a test program or something, not sure.
Any suggestions to fix this problem?
You can find the solution here: https://scikit-learn.org/stable/install.html
The problem occurs because the default path size limit is reached in your case, you can change this with the following steps:
open regedit tool (using windows cmd)
access the 'HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem' key
change the 'LongPathsEnabled' value to 1
reinstall sklearn using the command 'pip install --exists-action=i scikit-learn'
Edit: Yes I know this question already exists, except my question is a bit different and none of the solutions fixed it.
I do most of my Python stuff when I'm at work and not on my personal machine, but I decided to install it on my personal computer as well. I fresh installed python 3.6.1, and created a virtual environment with virtualenv. Then within the virtualenv I tried to pip install urllib (or any module) and I received the error:
(pdbot) C:\Users\user\Documents\pdbot>pip install urllib
Collecting urllib
Using cached urllib-1.21.1.tar.gz
Complete output from command python setup.py egg_info:

----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in C:\Users\user\AppData\Local\Temp\pip-build-50tn0wlb\urllib\
I read elsewhere that this error had something to do with setuptools not being properly installed. So I ran this to attempt to fix the issue:
easy_install -U setuptools
I ended up receiving an even weirder error next:
(pdbot) C:\Users\zeke\Documents\pdbot>easy_install -U setuptools

This looks like a permissions error, but I ran these both in an administrator command prompt (Windows 10) and got the same result. I am the only user on this computer and I have all admin permissions. Is this virtualenv causing an issue? How do I remedy it?
EDIT: I was able to fix the permissions issue by leveraging the python executable like so:
python -m easy_install -U setuptools
But it didn't fix the python setup.py egg_info issue. I still get this error message when trying to pip install anything:
Command "python setup.py egg_info" failed with error code 1 in C:\Users\user\AppData\Local\Temp\pip-build-50tn0wlb\urllib\
I have tried both python -m pip install urllib and pip install urllib and neither work.
I had the same problem when trying to install urllib, but after doing a pip search urllib, I discovered that the problem was due to the version of urllib. From the search:
$ pip search urllib
...
> urllib5 (5.0.0) - Just increment the number and create a new lib. Never fix the original one.
At the end, a simple
pip install urllib5
within an elevated shell solved it.
Your problem has to do with permissions. The related/similar tools setup_tools, easy_install, and pip all tend to set a default set of permissions on files and folders they try to create in the package installation folder(s), rather than trying to match access permissions of the location they're installing in.
On Linux systems, where files and folders individually have permissions, this is frequently bypassed with the sudo command. On Windows, the equivalent is to run the installer as an Administrator. Since you're in the console, you have to open a console with Administrator privileges to run the pip command in.
Notable under Windows, the modules installed with pip from an Administrator console are still accessible to all users of the system that have the proper path in the PYTHONPATH system environment variable. Under Linux however, the problem is exacerbated by the fact that the files themselves may not be created with read and execute access for other users and may need to have their permissions manually modified after installation.
WARNING: urllib vs urllib2 vs urllibx
Both other answers claim that the problem is you're not specifying the correct "version" of the module in the call to pip. Neither is correct, as the error clearly indicates an installation folder access permissions violation causing the failure, but they also incorrectly recommended VERY unsafe behavior.
pip install urllib != pip install urllib5 these are two completely different packages.
The documentation for pip (https://packaging.python.org/tutorials/installing-packages/#id17) clearly says the way to specify a module version explicitly is pip install 'urllib==5'.
As part of how the package management engine implemented by pip works, running the command pip install urllib will always try to use the latest version of the urllib package, so you shouldn't need to specify the version unless you have some reason that you need a very specific version of the module.
There are two points to make in order to answer your question:
1. You are lucky you did not install that package!
The package you were trying to install was a maliciously created python package that was designed to look like a real package (in this case urllib3). If you had installed it, the package would have operated as normal except it would have sent some basic information about the system on which you installed the package to a URL (you can see more details on this here). You can read more about this fake package at either of the following links:
https://app.threatconnect.com/auth/incident/incident.xhtml?incident=5256822&owner=Common%20Community (you can sign up for a free account to view this one)
http://www.nbu.gov.sk/skcsirt-sa-20170909-pypi/index.html
Sending basic information about your systems to an unknown source isn't the worst thing you could do, but is certainly something you want to avoid when possible.
2. To properly install a package...
Specifically urllib:
To install urllib, you need to specify the version of the package you would like to install. For example, pip install urllib3.
Any package in general:
As #Elisabete Coelho suggested, you can use the pip search <package-name> feature to view the available packages. This is not perfect, however, as it may list malicious libraries like the one you were trying to install. A good guideline is that you should follow the installation instructions in a package's documentation closely to avoid any unforeseen issues. This is just an unfortunate necessity of living in a world where people make pretend python packages.
For pip:
In my command prompt I type in:
C:/Python/Scripts/pip install aubio
Recommended by this site:
http://aubio.readthedocs.io/en/latest/python_module.html
And get this message:
http://imgur.com/a/vZxXg
It was suggested that I download a C++ compiler for Python, but doing so hasn't prevented the error.
So I tried installing the module via github.
For Github via pip:
I naturally installed Github and went back to my command prompt.
I typed in:
C:/Python/Scripts/pip install git+git://git.aubio.org/git/aubio
And when that failed:
C:/Python/Scripts/pip install git+git://git.aubio.org/git/aubio.git
I get the error:
Error [WinError 2] The system cannot find the file specified while executing c
ommand git clone -q git://github.com/aubio/aubio.git C:\Users\luke\AppData\Local
\Temp\pip-ornio5sm-build
Cannot find command 'git'
A lot of the other questions had answers concerning a broken setup file, but I'm not entirely sure how I check for that.
Thanks.
So this isn't the whole answer, but it will help anyone who comes here in the future.
I installed Github and not git. That's why the git command isn't recognized.
The correct place for installation[WINDOWS] is: https://git-for-windows.github.io/
I have the latest Anaconda Python distribution installed on Windows 8 and I am attempting to install the rpy2 package. I initially ran into several issues that I was able to circumvent but I'm now stuck on one particular error that I'm pasting below.
The command
pip install rpy2
exits with the following error message:
In file included from .\rpy\rinterface\_rinterface.c:58:0:
.\rpy\rinterface\_rinterface.h:8:15: fatal error: R.h: No such file or
directory
compilation terminated.
error: command 'gcc' failed with exit status 1
Any suggestions? The path to R.h is included on my environment.
Dr. Gohlke's binary is probably the easiest solution. But you need to change the Python installation path in your registry for this method to work. The relevant key is in HKEY_LOCAL_MACHINE\SOFTWARE\Python\PythonCore\2.7\InstallPath. Change it so that the anaconda Python is the default python installation. You can always change it back if you want.
I've seen some past threads that discuss similar problems, but none seem to be having exactly the problem that I am having. I was having problems with installing packages with Python, even though I'd managed to install them before. When I attempted to run gcc, it seemed to not be installed, so I uninstalled Xcode completely and just installed the command line tools (I really only use the command line tools, and could use the extra disk space).
Though the installer said that the installation was successful, gcc results in the following error:
xcrun: Error: could not stat active Xcode path '/Applications/Xcode.app/Contents/Developer'. (No such file or directory)
I have tried to redirect the path by using the following command:
export DEVELOPER_DIR="/Applications/Xcode.app/Contents/Developer"
It doesn't seem to work, though.
I've also tried using the following command:
sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer
but it returns the following error: xcode-select: Error: Path "/Applications/Xcode.app/Contents/Developer" is not a directory.
Which makes sense I think -- after all, I did uninstall Xcode, so I suppose I should point it to the Command Line tools directory? I'm not sure how to do this, though.
I'm using Mac OS X 10.8.5, by the way.
