Ipython打破:没有开始,说缺少'pathlib2'分布

Question

当我在终端执行ipython时,我看到以下错误

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

就在我跟随之前

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

我尝试使用apt-get卸载和安装,但它仍然无法工作并丢失分发错误.

我安装了pathlib2

sudo pip install pathlib2

但是在访问ipython时我又看到了另一个错误

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
