python - IPython 控制台找不到 "backports.shutil_get_terminal_size"并且不会加载

Question

我在 Windows 10 上运行 Python2.7，使用 Anaconda 进行 env 和大多数 pkg 管理。升级了许多软件包后，我的 ipython 控制台现在无法在任何 IDE 或控制台中启动。当我尝试在控制台上运行它时，出现此错误:

Traceback (most recent call last):
File "C:\Anaconda3\Scripts\ipython-script.py", line 3, in <module>
import IPython
File "C:\Anaconda3\lib\site-packages\IPython\__init__.py", line 48, in  <module>

File "C:\Anaconda3\lib\site-packages\IPython\utils\terminal.py", line 27, in <module>
import backports.shutil_get_terminal_size
ImportError: No module named backports.shutil_get_terminal_size

我尝试做的第一件事是:

pip install --upgrade backports.shutil_get_terminal_size

输出:

Requirement already up-to-date: backports.shutil_get_terminal_size in c:\anaconda3\lib\site-packages

我已经卸载并重新安装了两个 ipython

conda uninstall ipython
conda install ipython

和

pip uninstall ipython
pip install ipython

还是不行。请帮忙!

试试这个

conda config --add channels conda-forge
conda install backports.shutil_get_terminal_size
