Trouble installing Scrapy on Windows 64 bit

问题:

I am attempting to install Scrapy on my Windows 7 64 bit machine. I started by following the instructions here on Scrapy's documentation.

I got up until the command 'pip install Scrapy'. Everything works except that it cannot find 'libxml2':

Could not find function xmlCheckVersion in library libxml2. Is libxml2     installed?

I then visited this website to get the binaries of libxml2:

ftp://ftp.zlatkovic.com/libxml/64bit/

The instructions for installation of libxml2 are here: https://www.zlatkovic.com/libxml.en.html

They state that you should unzip the binaries and place the contents of the BIN folder in a path such as C:\WINDOWS. I did this. However, after attempting to install Scrapy again, I continue to receive the same error. Is there something I am missing?

Just installled Scrapy on Windows10 x64. It installs only with Python 2.7 on Windows. I used tutotial from here.

1. Download from the official site and install Python 2.7

2. Open Command promt (cmd) with full admin permissions and type:

   c:\python27\python.exe c:\python27\tools\scripts\win_add2path.py and press Enter

3. Install Microsoft Visual C++ for Python 2.7

4. Install OpenSSL (sorry, can't attach link because of small reputation). Download it to some folder, e.g. C:\Python27\Scripts and execute command from there: pip install pyOpenSSL-16.0.0-py2.py3-none-any.whl (the name of file could not be the same)

5. Install lxml just like previous file: pip install lxml-3.6.0-cp27-cp27m-win32.whl

6. Install Pywin32

7. And finally, install Scrapy - pip install Scrapy

Can recommend to download and install all needed soft for x32 architecture (even if you have x64 system).

It is recommended to use conda to install Scrapy on Windows. You can download Miniconda from here: http://conda.pydata.org/miniconda.html

Once you have conda installed you can follow this guide to learn about its subcommands: http://conda.pydata.org/docs/test-drive.html

In short, you can use this commands in your terminal:

1. Create an environment for scrapy: conda create -n scrapyenv python=2
2. Enable the scrapy environment: activate scrapyenv
3. Install scrapy: conda install -c scrapinghub scrapy

Edit: Scrapy's conda package has been moved to conda-forge channel. Use the command: conda install -c conda-forge scrapy

Hi this is what I did to get it installed under Win7/Win10:

• easy_install lxml
• pip install Scrapy
• install pywin32 as indicated by the docs

Then, follow the tutorial to be sure everything is working
