我在安装matplotlib软件包后无法将matplotlib.pyplot作为plt导入.任何建议都将非常感激.

>>> import matplotlib.pyplot as plt

长话短说:pythonw.exe什么都不做,python.exe什么都不接受(我应该使用哪一个？)

test.py:

print "a"

CMD窗口:

C:\path>pythonw.exe test.py
<BLANK LINE>
C:\path>

C:\path>python.exe test.py
  File "C:\path\test.py", line 7
    print "a"
            ^
SyntaxError: invalid syntax

C:\path>

请告诉我,我做错了什么.

我正在虚拟环境中使用flask.我能够用pip安装matplotlib,我可以import matplotlib在Python会话中.但是,当我导入它时

matplotlib.pyplot as plt

我收到以下错误:

>>> import matplotlib.pyplot as plt

之前已经问过这个问题,在这里,也在这里.但是,解决方案并没有解决我的问题.

最初的错误是,当我尝试时import matplotlib.pyplot,我得到:

回溯(最近一次调用最后一次):文件"",第1行,文件"/Users/XX/anaconda/lib/python2.7/site-packages/matplotlib/pyplot.py",第114行,在_backend_mod,new_figure_manager中, draw_if_interactive,_show = pylab_setup()文件"/Users/XX/anaconda/lib/python2.7/site-packages/matplotlib/backends/ INIT py"为32行,在pylab_setup全局(),当地人(),[backend_name ],0)文件"/Users/XX/anaconda/lib/python2.7/site-packages/matplotlib/backends/backend_macosx.py",第24行,来自matplotlib.backends import _macosx RuntimeError:Python未安装为框架.如果未将Python安装为框架,则Mac OS X后端将无法正常运行.有关在Mac OS X上安装Python作为框架的更多信息,请参阅Python文档.请重新安装Python作为框架,或尝试其他后端之一.如果您在虚拟环境中使用Matplotlib,请参阅Matplotlib中的"在虚拟环境中使用Matplotlib"常见问题解答

我按照解决方案添加了一个~/.matplotlib/matplotlibrc包含以下代码的文件:backend: TkAgg.这样做之后,我的错误变为:

/Users/XX/anaconda/lib/python2.7/site-packages/matplotlib/font_manager.py:273:UserWarning:Matplotlib正在使用fc-list构建字体缓存.这可能需要一点时间.warnings.warn('Matplotlib正在使用fc-list构建字体缓存.这可能需要一些时间.')objc [25120]:类TKApplication在/Users/XX/anaconda/lib/libtk8.5.dylib和/ /System/Library/Frameworks/Tk.framework/Versions/8.5/Tk.将使用两者之一.哪一个未定义.objc [25120]:类TKMenu在/Users/XX/anaconda/lib/libtk8.5.dylib和/System/Library/Frameworks/Tk.framework/Versions/8.5/Tk中实现.将使用两者之一.哪一个未定义.objc [25120]:类TKContentView在/Users/XX/anaconda/lib/libtk8.5.dylib和/System/Library/Frameworks/Tk.framework/Versions/8.5/Tk中实现.将使用两者之一.哪一个未定义.objc [25120]:类TKWindow在/Users/XX/anaconda/lib/libtk8.5.dylib和/System/Library/Frameworks/Tk.framework/Versions/8.5/Tk中实现.将使用两者之一.哪一个未定义.

我不知道如何解决这个问题.我没有使用虚拟机.你可以帮帮我吗？谢谢!

PS:我发现通过添加:

import matplotlib
matplotlib.use('TkAgg')

之前import matplotlib.pyplot,它似乎工作.但每次添加这两行代码都很烦人...有谁知道发生了什么以及如何解决它？谢谢!

我用pkg安装程序安装了Anaconda:

但是当我尝试使用matplotlib中的任何东西时,即:

 from matplotlib import pyplot as plt

我明白了

matplotlib与 MacOS 一起使用的问题是一个棘手的问题，已经通过许多讨论（见下文）进行了彻底审查。问题如下：

• 使用 MacOS Mojave 10.14.3
• 在 conda 环境中使用 python 3.7.2
• 使用 matplotlib 3.0.3

这是我想出的最简单的代码片段，它允许重现问题：

from matplotlib import pyplot as plt

x = [1, 2, 3]
y = [1, 2, 3]

plt.plot(x, y)
plt.show()

这会引发以下错误：

2019-03-22 12:25:43.429 python3.7[22209:554135] -[NSApplication _setup:]: unrecognized selector sent to instance 0x7f85866b9de0

我可以通过终端运行代码并使用图表弹出matplotlib窗口但不通过Pycharm.我得到的只是一个错误说:

See the Python documentation for more information on installing Python as a framework on Mac OS X. Please either reinstall Python as a framework, or try one of the other backends.
