Importing bs4 in Python 3.5
提问by anne_t
I have installed both Python 3.5 and Beautifulsoup4. When I try to import bs4, I get the error below. Is there any fix for that? Or should I just install Python 3.4 instead? Please be very explicit - I am new to programming. Many thanks!
我已经安装了 Python 3.5 和 Beautifulsoup4。当我尝试导入 bs4 时，出现以下错误。有什么解决办法吗？还是我应该只安装 Python 3.4？请非常明确 - 我是编程新手。非常感谢！

I'm afraid beautifulSoup4is not compatible with Python 3.5 at the moment. Use Python 3.4.
恐怕beautifulSoup4目前与 Python 3.5 不兼容。使用 Python 3.4。

I've sent the author a followup about this bug. If you want to install BeautifulSoup on Python 3.5a, I've uploaded a working patch of the source code to github.
我已向作者发送了有关此错误的后续信息。如果您想在 Python 3.5a 上安装 BeautifulSoup，我已将源代码的工作补丁上传到 github。

You can install it using setup.pyor just copy & paste this code into terminal.
您可以使用setup.py或仅将此代码复制并粘贴到终端中来安装它。
git clone https://github.com/jjangsangy/BeautifulSoup4 \
&& cd BeautifulSoup4 \
&& python3.5 setup.py install
I'm assuming here that since you're trying out 3.5a your python interpreter is installed with proper user permissions for your site-packagesdirectory so no sudo invocation is necessary.
我在这里假设，由于您正在尝试 3.5a，因此您的 Python 解释器安装了适当的用户权限，site-packages因此不需要 sudo 调用。

Update: BeautifulSoup 4.4.0 has been updated to be python3.5 compatible, so a pip install --upgrade beautifulsoup4should do the trick if you are still hitting this issue.
更新：BeautifulSoup 4.4.0 已经更新为与 python3.5 兼容，所以pip install --upgrade beautifulsoup4如果你仍然遇到这个问题，应该可以解决这个问题。
