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

Question

我尝试安装 BeautifulSoup 4

我在我的 mac 终端中输入以下内容后它起作用了

$ easy_install beautifulsoup4
$ pip install beautifulsoup4

但是当我将其导入 python 时，

from bs4 import BeautifulSoup

屏幕总是显示错误：

ImportError: cannot import name 'HTMLParseError'

然后我用谷歌搜索错误，发现在终端输入以下代码可以解决问题

pip install --upgrade beautifulsoup4

但是我输入之后，显示出来了异常：

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。感谢有人帮助

解决此问题的最简单方法是使用 Sudo。

    sudo pip install --upgrade beautifulsoup4

然而，sudo 并不总是被推荐这样做，你不应该以 root 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所玩的包。

您可以使用 virtualenvwrapper

sudo pip install virtualenvwrapper
mkvirtualenv
workon
python setup.py install
