Anaconda没有找到我用`pip`安装的软件包

Question

我是Anaconda版Python的新手,我已经遇到了令人不快的问题.

我按照这里的说明安装了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.然后我继续安装一些Anaconda首先没有包含的额外包装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.

有趣的是,这些包装可以很好地导入,当我没有运行Anaconda捆绑的python,删除后

# added by Anaconda 1.8.0 installer
export PATH="/home/username/anaconda/bin:$PATH"

来自我.bashrc:

在我运行的任何这些安装过程中,我是否遗漏了什么？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？

Answer 1

在评论中,确定pip使用的是/usr/bin/pip; 换句话说,系统pip.系统pip将安装到系统中site-packages,而不是Anaconda的site-packages.

解决方案是确保pip在安装与Anaconda一起使用的软件包时使用Anaconda.
