从Jupyter笔记本中安装pip包不起作用

Question

当我!pip install geocoder在Jupyter Notebook中运行时,我获得与pip install geocoder在终端中运行相同的输出,但是当我尝试导入时,地理编码器包不可用.

我正在使用Ubuntu 14.04,Anaconda 4.0.0和pip 8.1.2

安装地理编码器:

!pip install geocoder

The directory '/home/ubuntu/.cache/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.

然后尝试导入它:

import geocoder

---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)
<ipython-input-4-603a981d39f2> in <module>()
----> 1 import geocoder

ImportError: No module named geocoder

我也尝试关闭笔记本电脑并重新启动它,没有任何运气.

编辑:我发现使用终端在/home/ubuntu/.local/lib/python2.7/site-packages中安装地理编码器包并使用笔记本将其安装在/usr/local/lib/python2.7/dist-中不在路径中的包.sys.path.append('/usr/local/lib/python2.7/dist-packages')解决了当前会话的问题.

那么如何永久修改路径或告诉pip安装地理编码器的位置？

Answer 1

! pip install --user <package>

该!通知笔记本执行单元作为shell命令.

Answer 2

在IPython（jupyter）7.3和更高版本中，有一个魔术%pip和%conda命令可以安装到当前内核中（而不是安装到启动笔记本的Python实例中）。

%pip install geocoder

在早期版本中，您需要使用sys来解决问题，例如FlyingZebra1的回答

import sys
!{sys.executable} -m pip install geocoder

Answer 3

%pip install fedex    #fedex = package name

在2019年。

在较旧版本的conda中：

import sys
!{sys.executable} -m pip install fedex     #fedex = package name

*注意-您确实需要导入sys

Answer 4

尝试使用一些 shell 魔法：%%sh %%sh pip install geocoder 让我知道它是否有效，谢谢
