Invalid BeautifulSoup syntax in Python 3.4 (after 2to3.py)
I am trying to install Beautiful Soup 4 in Python 3.4. I installed it from the command line (got an invalid syntax error because I didn't convert it), did the conversion from the
, and now I am getting a new invalid syntax error.

BeautifulSoup 4 makes it unnecessary to manually convert to run in Python 3. Instead, you're trying to run Python 2-only code; it seems that you failed to convert the codebase correctly.
From the BeautifulSoup 4 page :
Beautiful Soup 4 works in both Python 2 (2.6+) and Python 3.
The line that is now throwing the exception should read:
print('Running CSS selector "%s"' % selector)
The codebase uses Python 2 syntax, but the installer will
convert this to compatible Python 3 syntax for you. Remember to install the project with
pip install beautifulsoup4
or using the version
bundled with Python 3.4:
python3.4 -m pip install beautifulsoup4
If you only downloaded the tarball, at least run
python3.4 setup.py install
for the installer to convert the codebase correctly for you; the converted code is copied to your Python setup. You can discard the loaded source directory after running the command, see How the installation works .
python3.4 setup.py build
and copy the directory
. Again, don't use the original source directory as it remains intact.
