问题 I recently started working on a project using just vim as my text editor with a virtualenv setup. I installed a few API's on this virtualenv from GitHub. Eventually, the project got a little bigger than vim could handle so I had to move the project to an IDE. I chose Aptana Studio 3. When I started up Aptana, I pointed the project directory to the virtualenv folder that I had created to house my project. I then pointed the interpreter at the Python executable in App/bin (created from

问题 Let's say we have two different Python packages from the same vendor, named with the same name -- foo . One is installed with pip and can be found in the /usr/lib/python/site-packages/foo directory, the second one is a system-wide dependency which you install with e.g. apt-get and the Python package ends up in /usr/lib/some-vendor-sdk/foo . Local and global foo do different things and I need them both to be importable in my source code, but I can only import one: $ python >>> import foo >>>

问题 I'm developing a Python utility module to help with file downloads, archives, etc. I have a project set up in a virtual environment along with my unit tests. When I want to use this module on the same computer (essentially as "Production"), I move the files to the mymodule directory in the ~/dev/modules/ mymodule I keep all 3rd-party modules under ~/dev/modules/ contrib . This contrib path is on my PYTHONPATH, but mymodule is NOT because I've noticed that if mymodule is on my PYTHONPATH, my

问题 I am struggling to add spark to my python path: (myenv)me@me /home/me$ set SPARK_HOME="/home/me/spark-1.2.1-bin-hadoop2.4" (myenv)me@me /home/me$ set PYTHONPATH=$PYTHONPATH:$SPARK_HOME:$SPARK_HOME/python:$SPARK_HOME/python/build:$SPARK_HOME/bin (myenv)me@me /home/me$ python -c 'import sys; print(sys.path)' ['', '/home/me/.virtualenvs/default/lib/python2.7', '/home/me/.virtualenvs/default/lib/python2.7/plat-x86_64-linux-gnu', '/home/me/.virtualenvs/default/lib/python2.7/lib-tk', '/home/me/

问题 Everywhere I see Python code importing modules using import sys or import mymodule How does the interpreter find the correct file if no directory or path is provided? 回答1: http://docs.python.org/3/tutorial/modules.html#the-module-search-path 6.1.2. The Module Search Path When a module named spam is imported, the interpreter first searches for a built-in module with that name. If not found, it then searches for a file named spam.py in a list of directories given by the variable sys.path . sys

问题 I have come across many similar questions, so it appears to be a common problem. However, there are some variances among the question specifics and nothing I have found has worked for me so far. My issue is that I have installed PyQt5 and Python 3 on OS X El Capitan and that every time PyQt5 is run, I receive an error. //anaconda/bin/python3.5 : Error while finding spec for ' PyQt5.uic.pyuic ' ( <class 'ImportError'> : No module named ' PyQt5 ') As you can see, I've been using Anaconda

问题 If I set PYTHONPATH to some path /path/to/modules/ , then the path is appended to sys.path and I can import modules/packages contained in /path/to/modules/ . However, if I only want access to a single module/package, then adding /path/to/modules/mymod.py or /path/to/modules/mypackage/ to sys.path does not work. So is there a way to add only a single module/package to the import search path, rather than adding the entire parent directory? I am asking because I need to import a single package

问题 I’m totally confused with new python 2.7.10. I've installed python 2.7.10 from tar.xz, which was downloaded from official site. Then I've linked /usr/local/bin/python2.7 with /usr/bin/python2.7 and /usr/bin/python, but when I try to import module, I get ImportError: No module named "module_name" . For example: python -c "import gtk" Traceback (most recent call last): File "<string>", line 1, in <module> ImportError: No module named gtk But if: cd /usr/lib/python2.7/dist-packages/gtk-2.0/

问题 I have ffmpeg and ffprobe installed on my mac (macOS Sierra), and I have added their path to PATH. I can run them from terminal. I am trying to use ffprobe to get the width and height of a video file using the following code: import subprocess import shlex import json # function to find the resolution of the input video file def findVideoResolution(pathToInputVideo): cmd = "ffprobe -v quiet -print_format json -show_streams" args = shlex.split(cmd) args.append(pathToInputVideo) # run the

问题 I'm having problems with my PythonPath on windows XP, and I'm wondering if I'm doing something wrong. Say that I have a project (created with Pydev) that has an src directory. Under src I have a single package, named common , and in it a single class module, named service.py with a class name Service Say now that I have another project (also created with Pydev) with an src directory and a common package. In the common package, I have a single script, client.py , that imports service. So in
