更新2：
我用pip卸载并重新安装，现在发生这种情况。似乎tk没有正确安装。

当我导入pyplot时，我得到了一个与Tkinter相关的错误。这只是一个渐渐消失的信息。

当我制作一个情节时，我得到一个奇怪的时间戳和没有情节的白色窗口，以及TclError。为什么会这样？我正在使用brew python（使用--use-brewed-tk标志安装）和pip matplotlib。

TclError
这看起来可能是一个conda错误。我永远不应该触及这些东西。
我卸载了anaconda软件包
conda uninstall Tk
conda uninstalal matplotlib
然后我得到了dupes tk并重新安装了python（based on this github issue）
brew install homebrew/dupes/tcl-tk
brew uninstall python
brew install python --with-brewed-tk
我现在可以毫无问题地导入pyplot
In [1]: from matplotlib import pyplot as plt
但我得到了同样奇怪的错误。如何正确安装tkinter？

This probably means that tk wasn't installed properly.
答案 0 :(得分：4)
我在10个小时前面临同样的问题。在我遵循How to import matplotlib in virtual env
中的说明后，问题得以实现我发现我已经在anacode和system中安装了tk。但我不知道Tk回调的原因。所以我所做的就是改变matplotlib的后端。
cd ~/.matplotlib
vi matplotlibrc
然后改变
backend : TkAgg
到
backend : Qt4Agg
它对我有用！
答案 1 :(得分：0)
我也必须安装PyQt。 因此，我为解决此问题所做的事情：
pip install pyqt5
~/.matplotlib/matplotlibrc vi ~/.matplotlib/matplotlibrc
更改
backend : TkAgg
到
backend : Qt5Agg
