我正在尝试使用matplotlib运行一个简单的脚本
import matplotlib.pyplot as plt
plt.figure(1) # the first figure
plt.subplot(211) # the first subplot in the first figure
plt.plot([1, 2, 3])
plt.subplot(212) # the second subplot in the first figure
plt.plot([4, 5, 6])
plt.figure(2) # a second figure
plt.plot([4, 5, 6]) # creates a subplot(111) by default
plt.figure(1) # figure 1 current; subplot(212) still current
plt.subplot(211) # make subplot(211) in figure1 current
plt.title('Easy as 1, 2, 3') # subplot 211 title
但是即使程序包显示在列表中，我也遇到以下错误
import matplotlib.pyplot as plt
ModuleNotFoundError: No module named 'matplotlib'
实际上，一切正常，直到我做了
conda update all
和 我还安装了QGIS3（仅适用于python 3.6，如果需要也可以安装GDAL），但我将其卸载以防引起问题。 现在，我无法让它在新的MG环境中再次工作。我遇到了更多错误，这是我尝试创建一个全新的新环境的第三次尝试，但是matplotlib仍然有问题。
答案 0 :(得分：0)
对于像我一样在Google上遇到这个问题的任何人，我只是删除并重新创建了conda环境：
conda env remove name_of_your_env
conda env create --name the_yml_defining_your_env
有关如何创建上述yml的信息，请查阅conda文档，因为相关部分位于here。链接的段落以及以下内容取决于您的用例。
