使用命令“pip3 install --upgrade pip”升级 pip 后出错

Question

My python library pandas,numpy, matplotlib are worked earlier, now I use command pip3 install --upgrade pip for upgrade pip and next " import pandas command is not working".

Traceback (most recent call last):
  File "<pyshell#0>", line 1, in <module>
    import pandas
  File "/home/desktop/.local/lib/python3.5/site-packages/pandas/__init__.py", line 17, in <module>
    "Unable to import required dependencies:\n" + "\n".join(missing_dependencies)
ImportError: Unable to import required dependencies:
numpy: Something is wrong with the numpy installation. While importing we detected an older version of numpy in ['/home/desktop/.local/lib/python3.5/site-packages/numpy']. One method of fixing this is to repeatedly uninstall numpy until none is found, then reinstall this version.

接下来我尝试使用命令 sudo pip3 install pandas 安装 pandas，我收到以下错误

desktop@desktop-All-Series:~$ sudo pip3 install pandas

    from pip import main

我正在使用 ubuntu 16.04 如何解决此问题？

Answer 1

它说 pip3 不支持。 您可以使用此命令。 试试看嘛，

conda install pandas

也试试这个 cmd

pip3 install --upgrade setuptools pip

Answer 2

使用命令后它现在正在工作

python3 -m pip install pandas --user

desktop@desktop-All-Series:~$ python3 -m pip install pandas --user
