Question

我正在尝试像这样导入matplotlib：

import matplotlib.pyplot as plt

为此我已经安装了matplotlib。

python -m pip install -U pip setuptools
python -m pip install matplotlib

虽然来自the examples的basic_example.py工作，但它突然停止与matplotlib的所有其他文件一起运行，给出了以下错误：

File "matplotlib.py", line 2, in <module>
  import matplotlib.pyplot as plt # pyplot module.
ImportError: No module named pyplot`

我试图检查模块是否仍在那里，似乎是。什么可能是错的？

Requirement already satisfied: matplotlib in c:\python27\lib\site-packages
Requirement already satisfied: numpy>=1.6 in c:\python27\lib\site-packages (from matplotlib)
Requirement already satisfied: python-dateutil in c:\python27\lib\site-packages (from matplotlib)
Requirement already satisfied: cycler in c:\python27\lib\site-packages (from matplotlib)
Requirement already satisfied: pyparsing!=2.0.4,!=2.1.2,>=1.5.6 in c:\python27\lib\site-packages (from matplotlib)
Requirement already satisfied: pytz in c:\python27\lib\site-packages (from matplotlib)
Requirement already satisfied: six>=1.5 in c:\python27\lib\site-packages (from python-dateutil->matplotlib)`

我使用的是Windows和Python 2.7。

Python 2.7在进入已安装的软件包之前首先尝试在当前工作目录中查找模块，因为您将测试文件命名为＃34; matplotlib.py＆＃34;，它会将其解释为matplotlib软件包。将您的测试文件重命名为其他内容，它应该没问题

ImportError：没有名为pyplot的模块（即使在安装matplotlib之后）
