Consider using the `--user` option or check the permissions.
You are using pip version 10.0.1, however version 18.0 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.所以我试着升级pip ..。
sudo pip install --upgrade pip

from pip import main
ImportError: cannot import name main显然，我的电脑上有一些旧的python 2.7。我不会用它的。如果解决方案涉及卸载它，我可以接受。提前谢谢。
我刚刚尝试了sudo pip3，因为我读了一些说明。这就是我现在得到的..。
sudo pip3 install beautifulSoup

好的，首先让我们修复您的Pip安装：
sudo apt-get install --reinstall python3-pip现在，您应该能够运行pip3 --version来检查Pip是否已安装并正常工作。如果没有，请在尝试任何其他操作之前让我知道。
要注意的要点：
- 在virtualenv外部运行Pip时，您需要使用
pip3，否则系统将尝试使用Python2的Pip。 - 如果您需要以根用户身份运行Pip，最好使用
sudo -H而不只是sudo-这将修复有关Pip的警告
如果你想安装Pip 18，我建议你在一个虚拟环境中安装--升级系统Pip充满了可能出错的东西。
例如：
# Create a new virtualenv:
python3 -m venv my_virtual_environment
# "Activate" it (you need to do this once per shell)
source my_virtual_environment/bin/activate
# Now you can use `pip`, `python` etc. and the changes will be kept in the `my_virtual_environment` directory
pip install -U pip setuptools wheel此外，要安装BeautifulSoup，您需要beautifulsoup4包- beautifulSoup很旧，不能与Python3一起使用：
