当我在终端中执行ipython时，我看到以下错误

aman@ebex-MacBookPro:~/ipython_work$ ipython

pkg_resources.DistributionNotFound: The 'pathlib2' distribution was not found and is required by ipython

就在此之前我跟着

 $ git clone --recursive https://github.com/ipython/ipython.git
 $ cd ipython
 $ pip install -e ".[notebook]"

从[如何自动保存ipython notebook]链接

http://stackoverflow.com/questions/21517296/how-to-autosave-ipython-notebook

我尝试使用apt-get卸载和安装，但它仍然无法正常运行并丢失分发错误。

我安装了pathlib2

sudo pip install pathlib2

但是在访问ipython时又是一次我看到了另一个错误

pkg_resources.DistributionNotFound: The 'backports.shutil_get_terminal_size' distribution was not found and is required by ipython

Answer 1

您需要手动安装一些软件包，如下所示：

pip install pathlib2
pip install backports.shutil_get_terminal_size
pip install enum34

Answer 2

对我来说，我也必须pip install enum34，但int32bit的回答是有效的。

pip install pathlib2 backports.shutil_get_terminal_size enum34

Answer 3

当我执行ipython interminal时，我看到同样的错误。通过安装有关异常的库来解决问题。

Answer 4

我从Anaconda“ Environments” 启动了Jupyter笔记本，并且打开了dos Windows，其中出现了所有有问题的启动包。

然后，我只需要在您的环境中逐个安装此窗口中缺少和提及的软件包。您可以根据需要多次重试同一过程。

Ipython打破：没有开始，说缺少'pathlib2'分布
