我有四个不同的文件:main,vector,entity和physics.我不会发布所有代码,只发布导入,因为我认为这就是错误所在.(如果你愿意,我可以发布更多)

主要:

import time
from entity import Ent
from vector import Vect
#the rest just creates an entity and prints the result of movement

实体:

from vector import Vect
from physics import Physics
class Ent:
    #holds vector information and id
def tick(self, dt):
    #this is where physics changes the velocity and position vectors

向量:

from math import *
class Vect:
    #holds i, j, k, and does vector math

物理:

from entity import Ent
class Physics:
    #physics class gets an entity …

我在Raspberry Pi上的Occidentalis操作系统(Raspbian的一个变种)上安装了OpenCV,使用了jayrambhia的脚本:https://github.com/jayrambhia/Install-OpenCV/blob/master/Ubuntu/opencv_latest.sh.它安装了2.4.5版本.

当我尝试在python程序中导入模块cv2时,我收到以下消息:

pi@raspberrypi~$ python cam.py
Traceback (most recent call last)
File "cam.py", line 1, in <module>
    import cv2
ImportError: No module named cv2

cv2.so存储在

pi@raspberrypi~$ python cam.py
Traceback (most recent call last)
File "cam.py", line 1, in <module>
    import cv2
ImportError: No module named cv2

在/ usr/local/lib中还有一些名为python3.2和python2.6的文件夹,这可能是个问题,但我不确定.

这可能是路径错误吗？任何帮助(Linux新手).

谢谢.

我正在使用Python并使用Flask.当我在我的电脑上运行我的主要的Python文件,它完美的作品,但是当我启动VENV和运行在终端的瓶的Python文件,它说,我的主要的Python文件中有"无模块命名BS4." 非常感谢任何意见或建议.

我在这里关注Flask教程:

http://blog.miguelgrinberg.com/post/the-flask-mega-tutorial-part-i-hello-world

我到达了尝试./run.py的地步,我得到:

Traceback (most recent call last):
  File "./run.py", line 3, in <module>
    from app import app
  File "/Users/benjaminclayman/Desktop/microblog/app/__init__.py", line 1, in <module>
    from flask import Flask
ImportError: No module named flask

这看起来类似于:

ImportError:没有名为flask的模块

但他们的解决方案没有帮助.作为参考,我也有这一个用户提到可能会导致问题的文件夹命名的烧瓶中.

我注意到使用基本操作系统Alpine与CentOS或Debian在Docker容器中安装Pandas和Numpy(它的依赖关系)需要更长的时间.我在下面创建了一个小测试来演示时差.除了Alpine更新和下载构建依赖项以安装Pandas和Numpy的几秒钟之外,为什么setup.py需要比Debian安装多70倍的时间？

有没有办法加速使用Alpine作为基本图像的安装,或者是否有另一个与Alpine相当的基本图像,最好用于像Pandas和Numpy这样的软件包？

在安装openerp 6的过程时,我想用这个命令生成一个配置文件,

cd/home/openerp/openerp-server/bin /

./openerp-server.py -s --stop-after-init -c /home/openerp/openerp-server.cfg

但它总是显示出一个信息

ImportError: No module named psycopg2

当我检查psycopg2包时,它已经安装好,

包python-psycopg2-2.4.5-1.rhel5.x86_64已安装和最新版本

没事做

这有什么问题？我的服务器是centos,我安装了python 2.6.7.

真的需要你的帮助..

我已经成功安装了一个库pip install <library-name>.但是当我尝试导入它时,python会提升ImportError: No module named <library-name>.为什么我会收到此错误,如何使用已安装的库？
