私が設定した仮想環境のsys.pathで、奇妙で予期しないことが起こっています。たとえば、クリーンな環境：

$ virtualenv test
$ source test/bin/activate
(test) $

これは予想されるPYTHONPATHです。

(test) $ python
>>> import sys
>>> print '\n'.join(sys.path)

/home/user/test/local/lib/python2.7/site-packages/setuptools-0.6c11-py2.7.egg
/home/user/test/local/lib/python2.7/site-packages/pip-1.1-py2.7.egg
/home/user/test/lib/python2.7/site-packages/setuptools-0.6c11-py2.7.egg
/home/user/test/lib/python2.7/site-packages/pip-1.1-py2.7.egg
/home/user/test/lib/python2.7
/home/user/test/lib/python2.7/plat-linux2
/home/user/test/lib/python2.7/lib-tk
/home/user/test/lib/python2.7/lib-old
/home/user/test/lib/python2.7/lib-dynload
/usr/lib/python2.7
/usr/lib/python2.7/plat-linux2
/usr/lib/python2.7/lib-tk
/home/user/test/local/lib/python2.7/site-packages
/home/user/test/lib/python2.7/site-packages

しかし、これは私が実際に得たものです：

(test) $ bpython
>>> import sys
>>> print '\n'.join(sys.path)

/usr/bin
/usr/lib/python2.7
/usr/lib/python2.7/plat-linux2
/usr/lib/python2.7/lib-tk
/usr/lib/python2.7/lib-old
/usr/lib/python2.7/lib-dynload
/usr/local/lib/python2.7/dist-packages
/usr/lib/python2.7/dist-packages

2つの異なるsys.pathの理由がわかりません。そのため、pipのインストールは機能しません！Virtualenv 1.7.2、Ubuntu 12.04、Python2.7.3を使用しています。どんな助けでもありがたいです。

Rather than installing one copy of bpython per virtualenv, I've added this function to my shell profile (for example ~/.bashrc or ~/.zshrc). It wraps the bpython command with some logic to load the virtual environment's python path (if you have an active virtual environment).

bpython() {
    if test -n "$VIRTUAL_ENV"
    then
        PYTHONPATH="$(python -c 'import sys; print ":".join(sys.path)')" \
        command bpython "$@"
    else
        command bpython "$@"
    fi
}

I found that I needed to deactivate and reactivate my virtualenv after installing bpython for it to work.

  1. pip install bpython
  2. deactivate
  3. . bin/activate # or your equivalent activation command

私の仮説は、新しいvirtualenvをアクティブ化した後、bpythonをインストールしていないというものです。

私はあなたが言ったようにそれを正確にフォローアップしました：

mkvirtualenv bpython
(bpython)~ $ pip install bpython
(bpython)~ $bpython

次に、コマンドを実行しました。

>>> import sys
>>> print '\n'.join(sys.path)

/Users/xxxx/.virtualenvs/bpython/bin
/Users/xxxx/.virtualenvs/bpython/lib/python2.7/site-packages/setuptools-0.6c11-py2.7.egg

/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac/lib-scriptpackages
/Users/xxxx/.virtualenvs/bpython/lib/python2.7/site-packages

そして、アクティブ化されたvirtualenvの下でpythonを実行することによって同じことを再び行いました

(bpython)~ $ python
.....
>>> import sys
>>> print '\n'.join(sys.path)

/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac/lib-scriptpackages
/Users/xxxx/.virtualenvs/bpython/lib/python2.7/site-packages

2つの結果に違いは見られませんでした

I also discovered that if you have bpython installed locally, you need to create your virtualenv with --no-site-packages for it to work properly. If you created your virtualenv without that flag, you can create an empty file named no-global-site-packages.txt in ~/.virtualenvs/<env-name>/lib/python2.7/ as noted in this Stack Exchange answer.
