我打开终端时看到此错误。它发生在我在我的计算机上安装 open cv 和 pandas 失败之后。

在这张图片中，错误是

/home/ujjwal/anaconda3/bin/python: Error while finding module specification for 'virtualenvwrapper.hook_loader' (ModuleNotFoundError: No module named 'virtualenvwrapper')
virtualenvwrapper.sh: There was a problem running the initialization hooks.

If Python could not import the module virtualenvwrapper.hook_loader,check that virtualenvwrapper has been installed for      VIRTUALENVWRAPPER_PYTHON=/home/ujjwal/anaconda3/bin/python and that PATH is set properly.

我如何解决这个问题？

我全新安装了 Ubuntu 16.04.6，在安装了一些 python 包（如下所列）并输入 Python3 并键入import pandas后，我收到此错误：

如何解决此问题或避免此错误？
上次我发这个的时候，我以为是因为我升级了 Ubuntu。升级不是问题。这些是我安装的其他软件包。

pip3 install pygame
pip3 install pymunk
pip3 install numpy
pip3 install matplotlib==3.0.3 #installed older version because new version requires python3.6
pip3 install scipy
pip3 install PyQt5
sudo pip3 install pyqtgraph
sudo apt-get install openmpi-bin
pip3 install cntk
pip3 install h5py
sudo pip3 install keras
pip3 install visvis --user
pip3 install seaborn --user
pip3 install pandas
python 16.04 pandas

我想在我的 ubuntu 18.04 上为 python2 安装 pandas。

当我尝试使用安装熊猫时

pip install pandas

我得到：

Requirement already satisfied: pandas in /home/apoorv/anaconda3/lib/python3.6/site-packages (0.24.1)
Requirement already satisfied: python-dateutil>=2.5.0 in /home/apoorv/anaconda3/lib/python3.6/site-packages (from pandas) (2.6.0)

Requirement already satisfied: six>=1.5 in /home/apoorv/anaconda3/lib/python3.6/site-packages (from python-dateutil>=2.5.0->pandas) (1.12.0)

我得到的错误：

今天我通过安装另一个包

pip3 install seaborn

这样做之后，我的熊猫包似乎坏了，我不知道如何修复它。我试图卸载并重新安装 pandas、numpy 和 seaborn，但总是得到同样的错误。

"Missing required dependencies {0}".format(missing_dependencies))
ImportError: Missing required dependencies ['numpy']

我怎样才能解决这个问题？

python3 numpy pandas
