Dear all, I have made a python program which I would like to be able to install on to linux machine. I want my python code to be able to use a standalone python with the libraries installed.
The code works with python3.4 and above and uses h5py and numpy packages. I was looking at the options I had and understood that it is a good idea to use virtualenv. I followed the following steps: 1. I installed anaconda3 python in to my home directory. I prepended the path to PATH, so python now refers to the anaconda version. The reason I am trying to use anaconda3 is because it has all the packages I need already installed. source $HOME/anaconda3/bin/activate ~/anaconda3 2. Then I try to create a virtualenv by running the following command in the destination directory. virtualenv -p /home/albert/anaconda3/bin/python3 --always-copy . This will give the following error: Running virtualenv with interpreter /home/albert/anaconda3/bin/python3 Using base prefix '/home/albert/anaconda3' New python executable in ./bin/python3 Traceback (most recent call last): File "/usr/lib/python3.3/site-packages/virtualenv.py", line 2308, in <module> main() File "/usr/lib/python3.3/site-packages/virtualenv.py", line 821, in main symlink=options.symlink) File "/usr/lib/python3.3/site-packages/virtualenv.py", line 956, in create_environment site_packages=site_packages, clear=clear, symlink=symlink)) File "/usr/lib/python3.3/site-packages/virtualenv.py", line 1247, in install_python shutil.copyfile(executable, py_executable) File "/home/albert/anaconda3/lib/python3.4/shutil.py", line 109, in copyfile with open(dst, 'wb') as fdst: PermissionError: [Errno 13] Permission denied: './bin/python3' If I run the same command using the administrator I get : Using base prefix '/home/albert/anaconda3' New python executable in ./bin/python3 Not overwriting existing python script ./bin/python (you must use ./bin/python3) Traceback (most recent call last): File "/usr/lib/python3.3/site-packages/virtualenv.py", line 2308, in <module> main() File "/usr/lib/python3.3/site-packages/virtualenv.py", line 821, in main symlink=options.symlink) File "/usr/lib/python3.3/site-packages/virtualenv.py", line 956, in create_environment site_packages=site_packages, clear=clear, symlink=symlink)) File "/usr/lib/python3.3/site-packages/virtualenv.py", line 1377, in install_python shutil.copyfile(py_executable_base, full_pth) File "/home/albert/anaconda3/lib/python3.4/shutil.py", line 108, in copyfile with open(src, 'rb') as fsrc: FileNotFoundError: [Errno 2] No such file or directory: 'python3' I get exactly the same error, even if I use compile python from source ( not using anaconda version). So my questions are: 1. Is virtualenv a good idea? 2. which python should I be using to create my virtualenv? System python? python compiled in user home directory? anaconda3? I´d really appreciate your help. Thank you very much in Advance, -- https://mail.python.org/mailman/listinfo/python-list
