在openpyxl中工作。我已经尝试了Python 3和pip3安装方法＆amp;他们似乎工作得很好，但是当我打开python3解释器＆amp;输入"sudo apt-get install python3-openpyxl"，我仍然可以获得
ImportError：没有名为'openpyxl'的模块。
它在python2解释器中运行良好，但我无法安装"import openpyxl"＆amp;需要在python3中编写我的程序。
我正在使用python3＆amp; Python版本3.5.2。我试过卸载＆amp;重新安装Ubuntu 16.04 LTS Xenial Xerus模块但仍然出错。有任何帮助吗？

我在Mac上遇到了同样的问题并使用：
pip3 install openpyxl
为我工作。
这也适用于Ubuntu 16.04。
答案 1 :(得分：0)
由于没有人回答这个问题，我将分享我最终的工作。我备份了我的文件＆amp;从可启动USB安装Ubuntu 16.10操作系统。使用Synaptic Package Manager为Python3安装openpyxl＆amp;它现在正在运作。
不确定这是一个真正的解决方案，但它可以用于我的目的。
