When I go ahead the import that library in python. 当我继续使用python导入该库时。 python says it could not find the modulus. python表示找不到模数。 

python3.5 -c 'import matplotlib; print(matplotlib.__version__, matplotlib.__file__)'

Traceback (most recent call last): File "", line 1, in ImportError: No module named 'matplotlib' 追溯（最近一次调用）：文件“”，ImportError中的第1行：没有名为'matplotlib'的模块

How can I fix this? 我怎样才能解决这个问题？

You need to install those libraries for the same version of python that you are using later to execute your code. 您需要为以后要用于执行代码的相同版本的python安装这些库。

So if you want to use Python 2.7 you have to call 因此，如果您想使用Python 2.7，则必须调用 

sudo pip2 install matplotlib

When using python 3.5 use it in a similar way 使用python 3.5时，以类似的方式使用它 

sudo pip3 install matplotlib
