我一個Ubuntu 14系統上安裝Python 2.7包和所遇到的問題，其中，「PIP凍結」產生這樣的輸出...如何從pip freeze異常中恢復？
$ pip freeze
Exception:

我不清楚是什麼原因導致這種狀況。
我的懷疑是，easy_install程序的失敗可能導致某些內容被破壞。
我試過重新安裝pip。
這沒有效果。
我懷疑我將不得不通過apt-get通過pip和python相關的ubuntu包完成所有python包的卸載和重新安裝。按包裝打包。
這將是非常耗時，我不確定它是否會達到預期的結果。
有沒有更好的方法來解決這個問題？
這裏是我的easy_install運行之前安裝的軟件包：
sudo apt-get install -y libprotobuf-dev libleveldb-dev libsnappy-dev libopencv-dev libboost-all-dev libhdf5-serial-dev protobuf-compiler gfortran libjpeg62 libfreeimage-dev libatlas-base-dev git python-dev python-pip libgoogle-glog-dev libbz2-dev libxml2-dev libxslt-dev libffi-dev libssl-dev libgflags-dev liblmdb-dev python-yaml python-numpy
這裏是最初的例外，我從easy_install的有：
$ sudo easy_install pillow

我後來能夠通過PIP安裝枕頭。
我注意到在我的路徑中似乎有2個不同的dist-packages。
這似乎有點奇怪。
>>> import sys
>>> import pprint
>>> pp = pprint.PrettyPrinter(indent=4)
>>> pp.pprint(sys.path)

這裏是我下面的全過程：
Install Caffe on EC2 from scratch
我明白，apt-get的支持畫中畫的版本已經很老了。
我試過更新點子。
我得到「由OS擁有」錯誤。
我不確定如何在這裏使用apt-get和這樣做的後果發生分歧。

升級點子也沒有的另一種方法：

是的。它完全複製了打印到屏幕上的信息。沒有額外的信息。 –
