Question

我在系统上安装了熊猫，但它无法正常工作并发送错误 ModuleNotFoundError：在ipython中没有名为“ pandas”的模块。

当我尝试在ipython中导入熊猫时收到错误消息：

    In [1]: import pandas
---------------------------------------------------------------------------
ModuleNotFoundError                       Traceback (most recent call last)
<ipython-input-1-38d4b0363d82> in <module>
----> 1 import pandas

ModuleNotFoundError: No module named 'pandas'

当我尝试在jupyter笔记本中导入熊猫时收到错误消息：

--------------------------------------------------------------------------

我尝试卸载并重新安装熊猫，但是没有运气

Answer 1

在您的iPython Notebook中，您可以尝试运行以下内容吗？

!pip install pandas

然后重新启动您的iPython Notebook内核？

您很可能已将熊猫安装到其他虚拟环境中。

Answer 2

如果您尝试使用其他解释器来运行代码（例如Visual Studio Code）或从终端运行，有时解释器的模块目录可能与使用pip的模块安装目录不同。
