I have installed the PyPy3 2.1 Beta 1 on my ubuntu. When I tried to import pymongo, a third party driver for mongodb, I was told "ImportError: No module named pymongo". So my questions are: (1)Does it mean I have to install pymongo again for pypy3 2.1 Beta 1? (2)If yes, http://doc.pypy.org/en/latest/getting-started.html#installing-pypy says: If you want to install 3rd party libraries, the most convenient way is to install distribute and pip: $ curl -O http://python-distribute.org/distribute_setup.py $ curl -O https://raw.github.com/pypa/pip/master/contrib/get-pip.py $ ./pypy-2.1/bin/pypy distribute_setup.py $ ./pypy-2.1/bin/pypy get-pip.py $ ./pypy-2.1/bin/pip install pygments # for example But, These instructions seems for pypy-2.1, the stable release for python 2.x only, not for PyPy3 which is used for python 3. Are the steps for installing 3rd party libraries for PyPy3 similar to the above ones? (3)If yes, I don't have curl installed in my ubuntu, do I have to install it? (4)I used "pip-3.3" which is particularly designed for python3 to install the pymongo instead of "pip". Is there any corresponding counterpart of pip-3.3 for PyPy3 2.1 Beta 1? If there is any, how to get it? Thank you.
