我是Anaconda版Python新手，已经遇到了令人不快的问题。
我按照the instructions here安装了Anaconda，它就像魅力一样，所有包含的包在需要时都可以正确导入。然后我继续安装了一些额外的包，Anaconda首先没有包含pip：
$ sudo pip install BeautifulSoup mrjob pattern
安装似乎很完美，但是当我尝试在ipython中导入它们时，事情变得令人沮丧：
Python 2.7.6 |Anaconda 1.8.0 (64-bit)| (default, Nov 11 2013, 10:47:18)
Type "copyright", "credits" or "license" for more information.

help -> Python's own help system.
object? -> Details about 'object', use 'object??' for extra details.

有趣的是，当我没有运行Anaconda的python包时，这些包可以很好地导入，删除后
# added by Anaconda 1.8.0 installer
export PATH="/home/username/anaconda/bin:$PATH"
来自.bashrc：

在我运行的任何安装过程中，我是否遗漏了任何内容？我应该手动将这些包链接到Anaconda，以便它知道在哪里找到它们吗？
答案 0 :(得分：20)
在评论中，确定使用的pip为/usr/bin/pip;换句话说，系统pip。系统pip将安装到系统site-packages中，而不是Anaconda的site-packages。
解决方案是确保在安装与Anaconda一起使用的软件包时使用Anaconda的pip。
