Python 从 Jupyter Notebook 中安装 pip 包不起作用

Installing a pip package from within a Jupyter Notebook not working

提问by Mikhail Janowski

When I run !pip install geocoderin Jupyter Notebook I get the same output as running pip install geocoderin the terminal but the geocoder package is not available when I try to import it.

当我!pip install geocoder在 Jupyter Notebook 中运行时，我得到的输出与pip install geocoder在终端中运行时的输出相同，但是当我尝试导入地理编码器包时，它不可用。

I'm using Ubuntu 14.04, Anaconda 4.0.0 and pip 8.1.2

我使用的是 Ubuntu 14.04、Anaconda 4.0.0 和 pip 8.1.2

Installing geocoder:

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.

Then try to import it:

然后尝试导入它：

import geocoder

----> 1 import geocoder

ImportError: No module named geocoder

I also tried shutting down the notebook and restarting it without any luck.

我还尝试关闭笔记本并重新启动它，但没有任何运气。

Edit:I found that using the terminal installs the geocoder package in /home/ubuntu/.local/lib/python2.7/site-packagesand using a notebook installs it in /usr/local/lib/python2.7/dist-packageswhich is not in the path. sys.path.append('/usr/local/lib/python2.7/dist-packages')solves the problem for the current session.

编辑：我发现使用终端安装地理编码器包/home/ubuntu/.local/lib/python2.7/site-packages并使用笔记本安装它/usr/local/lib/python2.7/dist-packages不在路径中。sys.path.append('/usr/local/lib/python2.7/dist-packages')解决了当前会话的问题。

So how can I permanently modify the path or tell pip where to install geocoder?

那么如何永久修改路径或告诉 pip 在哪里安装地理编码器？

! pip install --user <package>

The !tells the notebook to execute the cell as a shell command.

该!通知笔记本执行单元作为shell命令。

In IPython (jupyter) 7.3 and later, there is a magic %pipand %condacommand that will install into the current kernel (rather than into the instance of Python that launched the notebook).

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

%pip install geocoder

In earlier versions, you need to use sys to fix the problem like in the answer by FlyingZebra1

在早期版本中，您需要使用 sys 来解决问题，就像FlyingZebra1 的答案一样

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

%pip install fedex    #fedex = package name

in 2019.

在 2019 年。

In older versions of conda:

在旧版本的 conda 中：

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

*note - you do need to import sys

*注意 - 您确实需要导入 sys

In jupyter notebook under python 3.6, the following line works:

在 python 3.6 下的 jupyter notebook 中，以下行有效：

!source activate py36;pip install <...>

The problem is that pyarrowis saved by pipinto dist-packages(in your case /usr/local/lib/python2.7/dist-packages). This path is skipped by Jupyter so pipwon't help.

问题是它pyarrow被保存pip到dist-packages（在你的情况下/usr/local/lib/python2.7/dist-packages）。Jupyter 跳过了此路径，因此pip无济于事。

As a solution I suggest adding in the first block

作为解决方案，我建议在第一个块中添加

import sys
sys.path.append('/usr/local/lib/python2.7/dist-packages')

or whatever is path or python version. In case of Python 3.5 this is

或任何路径或python版本。在 Python 3.5 的情况下，这是

import sys
sys.path.append("/usr/local/lib/python3.5/dist-packages")

Alternative option : you can also create a bash cell in jupyter using bash kernel and then pip install geocoder. That should work

替代选项：您还可以使用 bash 内核在 jupyter 中创建一个 bash 单元，然后pip install geocoder. 那应该工作

Try using some shell magic: %%sh %%sh pip install geocoderlet me know if it works, thanks

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
