python 3.4.0 email package install: ImportError: N

问题:

I have a virtualenv running python 3.4.0 pip version is pip 1.5.4 I did pip install email and get the error: ImportError: No module named 'cStringIO' at the end of the process (which failed) How does one get the email package for python 3.4.0

回答1:

From Python 3.0 changelog;

The StringIO and cStringIO modules are gone. Instead, import the io module and use io.StringIO or io.BytesIO for text and data respectively.

From the Python 3 email documentation it can be seen that io.StringIO should be used instead:

from io import StringIO
from email.generator import Generator
fp = StringIO()
g = Generator(fp, mangle_from_=True, maxheaderlen=60)
g.flatten(msg)
text = fp.getvalue()

I had the same issue because my file was called email.py. I renamed the file and the issue disappeared.
