我正在尝试安装pip.py. 每当我搜索安装程序时,它都会打开一个包含代码的新选项卡,我无需下载任何内容.我打算做什么,我的意思是将代码复制粘贴到Python解释器中吗？如何让它适用于Windows 7 32位版本？

我已经尝试过pip install psycopg2以下错误:

错误:

刚开始学习Python.而且我在使用Pyperclip模块时遇到了麻烦.

当我尝试pip install pyperclip在命令行中使用它时,它会显示以下错误:

pip install pyperclip
          ^
SyntaxError: invalid syntax

我在Windows 7桌面上运行Python 3.5(32位).

我想安装feedparser.

这是尝试在Windows命令行中安装feedparser时发生的情况.

> python.exe setup.py install
running install
running bdist_egg
error: error in 'egg_base' option: 'feedparser does not exist or is not a directory

我正在使用Python 2.7(feedparser网站声称"它在Python 2.4上一直运行到3.2").

当我尝试进入pip install scikit-learnPython shell时,我收到了"无效语法"消息.我已经安装了Scipy和Numpy,所以不应该有任何依赖性问题.怎么了？我还是Python的新手,所以我不想手动安装模块.我在Vista 32位上使用Python 2.7.

谢谢你的帮助.

我正在使用 Sublime Text 3 和 Package Control

前几天我通过 Package Control 安装了 Pylint
但它不起作用，只要我打开 Sublime Text 3 就会跳出这个警告对话框

我该如何修复它？

我正在尝试在Windows 8.1中安装并运行OpenCV 3.0.0 for python 3.4.2.

1. 我从http://opencv.org/下载了OpenCV文件.
2. 在C:中提取文件夹.
3. 我进入了系统 → 高级系统设置 → 高级 → 环境变量
4. 在"用户变量框架"中添加新变量.将其命名为"OPENCV_DIR",其值为"c:\ opencv\build\x64\vc12".
5. 在路径末尾添加:";; C:\ opencv; C:\ opencv\build;%OPENCV_DIR%\ bin"
6. 我从"C:\ opencv\build\python\2.7\x64"中获取了存档"cv2.pyd"并将其复制.
7. 我粘贴了C:\Python34\Lib\site-packages.

最后我去了Python 3.4.2的IDLE并写了(这是在将精美复制到Python目录之前发生的):

import cv2
Traceback (most recent call last):
  File "<pyshell#0>", line 1, in <module>
    import cv2
ImportError: No module named 'cv2'

这是在我将文件复制到Python目录后发生的:

import cv2
Traceback (most recent call last):
  File "<pyshell#3>", line 1, in <module>
    import cv2
ImportError: DLL load failed: The specified module could not be found. …

我在Windows上安装了python 2.7.10,并尝试使用以下命令在命令行上安装Django:

C:/users/user/myproject> python pip install django

这会显示以下错误:

python: can't open file 'pip' [Errno 2] No such file or directory

安装了Python C:\Python27,PATH环境变量也设置为.

为什么pip无法正常工作？

我尝试安装，PySide但是从电源外壳中出现错误，如下所示：

pip：术语“ pip”不被识别为cmdlet，函数，脚本文件或可运行程序的名称。检查名称的拼写，或者是否包含路径，请验证路径是否正确，然后重试。在第1行：char：1
+ pip install -U PySide
+ ~~~
+ CategoryInfo：ObjectNotFound：（pip：String）[]，CommandNotFoundException
+ FullyQualifiedErrorId：CommandNotFoundException

每当我尝试使用 pip 时，使用任何命令都会得到以下信息：
