python - BeautifulSoup 导入错误

Question

我正在尝试编写一个简单的本地 python 脚本来进行一些 html 解析。我安装了 beautifulsoup4 并使用

导入了它

from bs4 import BeautifulSoup

但是我得到了错误:

Traceback (most recent call last):
  File "scrape_descriptions.py", line 1, in <module>
    from bs4 import BeautifulSoup
ImportError: No module named 'bs4'

我几乎尝试过以各种方式安装 BS4。我先做了

sudo pip install BeautifulSoup4

然后我尝试从网站下载实际文件并运行

sudo python setup.py install

最后我试过了

sudo su
easy_install BeautifulSoup4

所有这些操作似乎都已成功完成。但我仍然收到此错误。我搜索了其他帖子，但几乎所有帖子都只是安装说明，我已经完成了。

打字

pip freeze

显示 bs4 已安装但正在运行

$ python3 -i
>>> help('modules')

似乎没有列出 bs4。

编辑 1:运行 sudo pip3 install BeautifulSoup 出现此错误:

编辑 2:已解决! pip3 失败的原因是因为我正在使用

sudo pip3 install BeautifulSoup

代替

sudo pip3 install BeautifulSoup4

有效。谢谢!
