Python 64位存储的字符串长度不如32位python

[英]Python 64 bit not storing as long of string as 32 bit python

原文 2015-02-19 20:47:02 8 1 python/ python-2.7/ beautifulsoup/ 32bit-64bit

I have two computers, both running 64-bit Windows 7. One machine has python 32-bit, one is running python 64-bit. 我有两台计算机，都运行64位Windows7。一台计算机具有python 32位，一台正在运行python 64位。 Both machines have 8GB of RAM. 两台机器都有8GB的RAM。

I'm using BeautifulSoup to scrape a webpage, but I've been running into issues on my python64 machine. 我正在使用BeautifulSoup抓取网页，但是我一直在python64机器上遇到问题。 I've been able to figure out that the output of my len(str(BeautifulSoup(request.get(http://www.sampleurl.com).text))) in 64bit is only returning 92520 characters but on the same, static, site on my python32-bit machine, it's returning 135000 characters. 我已经弄清楚了我的len(str(BeautifulSoup(request.get(http://www.sampleurl.com).text)))在64位的输出仅返回92520个字符，但在相同的情况下，静态，在我的python32位计算机上，返回135000个字符。

At some point in the past on my python64-bit machine I had python32-bit, but uninstalled it to install python64-bit because I was having issues installing scipy using pip install (turns out that wasn't the issue). 在过去的某个时候，我在python64位计算机上安装了python32位，但是将其卸载以安装python64位，因为我在使用pip install安装scipy时遇到了问题（原来不是问题）。

Anyway, I'm unsure as to why my 64bit python machine isn't returning the entire html string and I was wondering if anyone can help me understand what is going on and how can I fix it. 无论如何，我不确定为什么我的64位python机器不返回整个html字符串，我想知道是否有人可以帮助我了解发生了什么以及如何修复它。

This is not a 32bit / 64bit issue. 这不是32位/ 64位问题。 You are most likely a parser issue; 您很可能是解析器问题； one machine using lxml vs. html.parser on the other, for example. 例如，一台机器使用lxml vs. html.parser 。

Different parsers deal differently with broken HTML, and lxml is the default only when installed. 不同的解析器对损坏的HTML的处理方式不同，并且lxml仅在安装时才是默认值。

See for example: 参见例如：

etc. 等等

Run import lxml on both machines to verify. 在两台计算机上运行import lxml进行验证。 When you replaced your Python installation on one machine with a 64-bit version, you likely didn't include a compatible lxml version. 当在一台计算机上用64位版本替换Python安装时，您可能未包含兼容的lxml版本。
