如何在 Windows 7 64 位上安装 PyOpenSSL？

发布于 2024-10-20 21:19:52 字数 583 浏览 5 评论 0原文

要让 Scrapy 在 HTTPS 上运行，我需要 PyOpenSSL，但我似乎无法让它发挥作用。

那么，有 64 位版本可用吗？ 我没有看到... 我已经安装了 32 位版本，但是...

我目前从 Scrapy 收到此错误：

ERROR: Error downloading <https://SOME_PRIVATE_URL_HERE>:  
  [Failure instance: Traceback: <class 'scrapy.exceptions.NotSupported'>:
  HTTPS not supported: install pyopenssl library

有谁知道如何获取或编译 64 位版本吗？或者说这是没有必要的？

原文

To get Scrapy working on HTTPS, I need PyOpenSSL, but I can't seem to get this to work.

So, is there a 64-bit version available? I don't see one... I have installed the 32-bit version but...

I currently get this error back from Scrapy:

ERROR: Error downloading <https://SOME_PRIVATE_URL_HERE>:  
  [Failure instance: Traceback: <class 'scrapy.exceptions.NotSupported'>:
  HTTPS not supported: install pyopenssl library

Does anyone have a clue how to obtain or compile a 64-bit version? Or is that unneccesary?

编辑：包括来自 steamforge 的内容：

注释

Scrapy 必须与 Python 2.5、2.6 或 2.7（不是 3.x）一起安装
Python 2.7（和 3.2）不加载正确的 32 位兼容
Windows 注册表项

安装过程

下载和安装安装 Python 2.7.2（使用 Windows Installer）
http://www.python.org/getit/
转到搜索程序和文件 开始底部的栏
菜单并输入“regedit”并按 Enter
使用左窗格导航到
“HKEY_LOCAL_MACHINE\SOFTWARE\Python” &单击它（突出显示
蓝色）
1. 选择分支后，转到文件 -->导出
2. 将文件保存在您可以轻松访问的位置
3. 在您喜欢的文本编辑器中打开文件
4. 在“SOFTWARE”和“\Python”之间插入“\Wow6432Node”
  每行（一个简单的方法是查找并替换
  在查找字段中输入“SOFTWARE”，在字段中输入“SOFTWARE\Wow6432Node”
  替换字段
5. 保存文件
6. 导航到您保存该文件的位置，然后双击它
  启动注册表修改
现在从以下位置下载 Scrapy 0.14 Windows 安装程序
http://pypi.python.org/pypi/Scrapy
双击 Scrapy 安装程序，一切都应该工作正常。
下载并安装适用于 Python 2.7 64 位的 Twisted 11.1.0
http://twistedmatrix.com/trac/wiki/Downloads
下载并安装 Zope。界面
1. 从以下位置下载 distribution_setup.py
  http://python-distribute.org/distribute_setup.py（右键单击
  &保存），然后双击安装
2. 从以下位置下载 zope.interface-3.8.0-py2.6-win-amd64.egg
  http://pypi.python.org/pypi/zope.interface/3.8 .0#下载
3. 打开命令提示符（在相同的搜索程序中键入“cmd”
  和文件窗格如上）并导航到您的 Python 脚本
  文件夹（类似于“cd C:\Python27\Scripts”）
4. 输入“easy_install
  C:\Downloads\zope.interface-3.8.0-py2.6-win-amd64.egg”
  （将 C:\Downloads\ 替换为您下载的位置
  Zope.Interface to）并按 Enter
下载并安装 lxml-2.3.2.win-amd64-py2.7.‌exe
http://www.lfd.uci.edu/~gohlke/pythonlibs/
下载并安装
egenix-pyopenssl-0.13.0_1.0.0g_1.win-amd64-py2.7.msi 来自
http:// /www.egenix.com/cryptodownload/?file=egenix-pyopenssl-0.13.0_1.0.0g_1.win-amd64-py2.7.msi
- 当它要求您导航到 Python 2.6 目录时，只需
  将其指向您的 Python 2.7 目录（默认为 C:\Python27）
安装 w3lib
1. 打开命令提示符（开始 -> 搜索程序和文件 ->
  “cmd”）
2. 导航到您的 Python 脚本文件夹（名义上
  “C:\Python27\Scripts”)
3. 输入“easy_install w3lib”并按 Enter
现在我们只需要将 Python Scripts 文件夹添加到系统路径
所以我们可以使用scrapy
1. 单击“开始菜单”按钮，然后右键单击“计算机”，然后
  选择“属性”
2. 点击左侧栏中的“高级系统设置”
3. 点击“环境变量...”
4. 在（下部）系统变量窗格中找到“Path”变量
  并双击它
5. 单击“变量值：”窗格并点击“结束”按钮
6. 键入或粘贴“;C:\Python27\Scripts\”（修改为任意位置）
  你安装了Python）在该行的末尾
7. *请务必不要干扰或更改其中的任何现有信息
8. 点击“确定”、“确定”、“确定”、“X”

Actually, step 9 at this website will resolve your issue.

EDIT: Including the content from steamforge:

Notes

Scrapy must be installed with Python 2.5, 2.6, or 2.7 (NOT 3.x)
Python 2.7 (and 3.2) do not load the correct 32-bit compatible
Windows Registry Keys

Install Procedure

Download & install Python 2.7.2 (using the Windows Installer) from
http://www.python.org/getit/
Go to the Search programs and files bar at the bottom of the start
menu and type “regedit” and hit enter
Using the left pane navigate to
“HKEY_LOCAL_MACHINE\SOFTWARE\Python” & click on it (highlighting
it in blue)
1. With the branch selected go to File --> Export
2. Save the file somewhere you can get to it easily
3. Open the file in your favorite text editor
4. Insert "\Wow6432Node" inbetween “SOFTWARE” and "\Python" on
  every line (an easy way to do this is to do a find and replace
  with “SOFTWARE” in the Find Field and “SOFTWARE\Wow6432Node” in
  the Replace Field
5. Save the file
6. Navigate to where you saved said file and double click on it to
  initiate a Registry Modification
Now download the Scrapy 0.14 Windows installer from
http://pypi.python.org/pypi/Scrapy
Double click the Scrapy Installer and everything should work fine.
Download and install Twisted 11.1.0 for Python 2.7 64 bit from
http://twistedmatrix.com/trac/wiki/Downloads
Download and install Zope.Interface
1. Download distribute_setup.py from
  http://python-distribute.org/distribute_setup.py (right click
  & save), then double click it to install
2. Download zope.interface-3.8.0-py2.6-win-amd64.egg from
  http://pypi.python.org/pypi/zope.interface/3.8.0#downloads
3. Open a command prompt (type “cmd” into the same Search programs
  and files pane as above) and navigate to your Python Scripts
  folder (something like “cd C:\Python27\Scripts”)
4. type “easy_install
  C:\Downloads\zope.interface-3.8.0-py2.6-win-amd64.egg”
  (replacing C:\Downloads\ with wherever you downloaded
  Zope.Interface to) and hit enter
Download and install lxml-2.3.2.win-amd64-py2.7.‌exe from
http://www.lfd.uci.edu/~gohlke/pythonlibs/
Download and install
egenix-pyopenssl-0.13.0_1.0.0g_1.win-amd64-py2.7.msi from
http://www.egenix.com/cryptodownload/?file=egenix-pyopenssl-0.13.0_1.0.0g_1.win-amd64-py2.7.msi
- When it asks you to navigate to a Python 2.6 Directory, just
  point it to your Python 2.7 Directory (C:\Python27 by default)
Install w3lib
1. Open a command prompt (Start -> Search programs and files ->
  “cmd”)
2. Navigate to your Python Scripts Folder (nominally
  “C:\Python27\Scripts”)
3. Type “easy_install w3lib” and hit enter
Now we just need to add the Python Scripts folder to the System Path
so we can use scrapy
1. Click the “Start Menu” button and Right Click on “Computer” and
  select “Properties”
2. Click “Advanced system settings” in the left bar
3. Click “Environment Variables...”
4. Find the “Path” variable in the (lower) System variables Pane
  and double click on it
5. Click in the “Variable value:” pane and hit the “End” button
6. Type, or paste, ";C:\Python27\Scripts\" (modify for wherever
  you installed Python) at the end of the line
7. *Be sure not to disturb or change any of the existing information there
8. Hit OK, OK,OK, X
