I was installing anaconda for my Ubuntu 18.04 machine but I happened to exit the terminal accidentally after a couple of hours. I wish to resume the installation process at that step where it was installing various packages like sklearn, qt, etc.
I get the following error when I run bash Anaconda3-2018.12-Linux-x86_64.sh and give the path where I want my conda home to be (not the default home folder)
ERROR: File or directory already exists: '<path_to_anaconda>/anaconda3'
If you want to update an existing installation, use the -u option.
How do I approach this error? How do I recover from partial installation?
Also conda update --all gives an error conda:command not found

I have successfully installed Anaconda on my drive D and added it to my path so that I am able to access it from cmd without using the Anaconda prompt.
However, after running where conda on the Anaconda prompt, I got the 3 different locations
- D:\Anaconda\Library\bin\conda.bat
- D:\Anaconda\Scripts\conda.exe
- D:\Anaconda\condabin\conda.bat
to set as paths but after doing that, the conda command on my command line still does not work.
From the error image and description of the issue, I can see that you have installed the anaconda in the D:\ drive and tried to access it through the C:\ drive.
To access the conda in command prompt, you need to run the below commands :
C:\Users\Loni Tande>cd D:\Anaconda\Scripts
D:\Anaconda\Scripts>conda
D:\Anaconda\Scripts>conda --version
Please make sure you have the latest Anaconda version installed in your system to access all its functionalities.
I am getting this error in windows platform, after creating virtual environment whenever I am trying to run conda command to install any package this error occurs.
(py36) C:\Users\ND_Londhe>conda install -c anaconda spyder
Solving environment: failed
NotWritableError: The current user does not have write permissions to a required path.
path: C:\C:\Users\ND_Londhe\Anaconda2\pkgs\urls.txt
All solutions out there are for ubuntu.
yeah, you must use your root permission to install the package ,so Don't use the user to install. try it and it's fine!
I am trying to reinstall anaconda 64 bit on Windows 10 to use Python 3.6 and the installations works right till the end but it fails executing the post install script with following error.
You have some missing files, try to uninstall and download it again. Don't try to pause the files, it might cause these kind of errors.
I got it running after installing in a different directory. Just make sure you don't install it in the default location provided. I made a new directory in C-Drive and installed anaconda in it. My install location is C:\Anaconda3. And it worked finally
I am very new to python and plan to use psychopy quite a lot. I am on a work computer but have full admin rights.
Psychopy came with python version 2.7.11 and includes setuptools already.
I am trying to install the selenium module, but having trouble getting pip to work at all.
In cmd, it is recognising the 'python' command, so I know python is in my path.
I get the message "can't open file 'pip': [Errno2] No such file or directory" from:
python pip install selenium
I get " 'pip' is not recognised as an internal or external command" from:
pip install selenium
When I change directory to where pip is located, I get:
Fatal error in launcher: Unable to create process using '"'
Using pip2 makes no difference.
It seems a simple thing but where am I going wrong with this?!
I never really got to the bottom of this, but this is what I found out and here are the commands that worked for me in Windows. Be aware that I am far from expert!
To run python scripts (*.py) from command line (cmd) then C:\PsychoPy2 and C:\PsychoPy2\DLLs need to be in path. ('Path' contains directories or file extensions that can be more globally accessed, i.e. do not require you to change the prompt to the relevant directories first).
To check, open cmd and either type echo %PATH% or just type python. (If python starts, the line will say >>>. You can exit by typing quit())
To add to path, get properties of computer, then advanced system settings, then environment variables.
To check pip.exe (a sort of installation wizard) is installed, either search for the file, or check C:\PsychoPy2\Scripts for it. This may also need to be in path.
To reinstall the latest versions of pip and setup tools, I went to cmd and typed:
python -m pip install -U pip setuptools
If the same code did not work for other modules (which in my case was due to network access), then I downloaded the wheel file (*.whl) for that module (from their website) and ran the following code:
python -m pip install c:/modulename.whl
These may not be the correct ways of doing things, but they worked for me when I couldn't get other ways to work!
I've just had the exact same issue with the pip install, and a conflict with PsychoPy installations. I think it's because python automatically wants to call on the path that's been set by Psychopy, so it can't get to the 'pip' folders that for me, remain in a temporary/hidden file. This wasn't intuitive for me - on any machine without psychopy python just 'works' when you download it.
I've been using Python 2.7.10 in a virtualenv environment for a couple of months.
Yesterday, activating the environment went fine, but today suddently I get this cryptic error when trying to start Python from Terminal:
Illegal instruction: 4
I have made no changes to my environment (AFAIK), so I'm having a difficult time trying to come to terms with what this error is and what caused it.
Python works fine outside of this virtualenv environment. When running via /usr/local/bin it presents no problem.
I've had this problem a number of times now. While I can't say for certain what the actual issue is, I believe it basically means that some file(s) in the virtualenv installment of Python have become corrupted.
I keep my virtual environment in a synced Dropbox folder, so that may be a large contributor to the issue.
Restoring the virtual environment from a back-up archive worked for me. Or simply reinstall an identical virtual environment.
First, try activating the faulty environment by cd <path/to/old_env> and source /bin/activate.
If it's successfully activated, cd to an accessible location on the drive and run pip freeze > requirements.txt to export a list of currently installed Python modules.
Delete the old environment.
Install a new virtual environment of the latest version of Python 2 that you have on the computer, via virtualenv <path/new_env>
Or, if you want to use a specific Python version, first make sure you have you have it on your drive, and then do virtualenv -p <path>. Assuming that you have downloaded the Python version with Homebrew, e.g.: virtualenv -p /usr/local/bin/python2.6 <path/new_env>
Activate the virtual environment via cd <path/new_env> and then do source /bin/activate.
Assuming that you kept a list of modules to reinstall by previously doing pip freeze > requirements.txt, cd to the folder where the text file is located and do pip install -r requirements.txt.
Otherwise, reinstall the modules with pip manually.
I had same problem and found solution by uninstalling psycopg2 and installing older version. As I understood my comp was not supporting some commands in new version
