Question

我尝试安装BeautifulSoup 4

在我输入我的mac终端

后输入了

$ easy_install beautifulsoup4
$ pip install beautifulsoup4

但是当我在我的python中导入它时，

from bs4 import BeautifulSoup

屏幕始终显示错误：

ImportError: cannot import name 'HTMLParseError'

然后我用google搜索错误，通过在终端输入以下代码找到可以解决问题

pip install --upgrade beautifulsoup4

但是在我输入后，它显示出来了例外：

Traceback (most recent call last):
  File "//anaconda/lib/python3.5/site-packages/pip/basecommand.py", line 215, in main
    status = self.run(options, args)

    with open(dst, 'wb') as fdst:
PermissionError: [Errno 13] Permission denied: '//anaconda/lib/python3.5/site-packages/bs4/__init__.py'

我不知道如何修复它。谢谢你的帮助

Answer 1

解决这个问题的最简单方法是使用Sudo。

    sudo pip install --upgrade beautifulsoup4

但是并不总是建议sudo这样做，不应该以root用户身份安装任意代码。

我的建议是创建一个virtualenv，在使用sudo以root身份安装它们之前安装包。

您可以使用virtualenvwrapper

sudo pip install virtualenvwrapper
mkvirtualenv
workon
python setup.py install

通过输入pip install --upgrade beautifulsoup4安装ErrorSoup 4安装错误
