Mac上的Python 3.5.1 Pip安装错误

Question

Installed Python 3.5.1 on Mac. When I try to download a module from Python's standard library such as pip install BeautifulSoup, I receive the error below:

Collecting BeautifulSoup

Using cached BeautifulSoup-3.2.1.tar.gz Complete output from command python setup.py egg_info: Traceback (most recent call last): File "", line 1, in File "/private/var/folders/bz/2h0jcnq54pzcvjp2x0mhrc6r0000gn/T/pip-build-b_z00926/BeautifulSoup/setup.py", line 22 print "Unit tests have failed!" ^ SyntaxError: Missing parentheses in call to 'print'

----------------------------------------

Command "python setup.py egg_info" failed with error code 1 in /private/var/folders/bz/2h0jcnq54pzcvjp2x0mhrc6r0000gn/T/pip-build-b_z00926/BeautifulSoup/

Answer 1

That appears to be an old version of BeautifulSoup. Try this instead:

pip install beautifulsoup4

Answer 2

the missing parentheses part might suggest that pip uses python2 by default when you actually need python3

a simple workaround:

python3 -m pip install beautifulsoup # or beautifulsoup4

that has the same effect as pip install, but explicitly specifies which python to use

Answer 3

Try using pip2 (for Python 2) or pip3 (for Python 3) instead of just pip . It might be using the wrong version of pip for the Python version you are trying to use.
