我在/ usr / bin / python中有原始的Python 2.7.5，我通过在/ usr / local / bin / python3下载Python 3.5.1软件包安装了Python3，然后按如下方式安装了BeautifulSoup4：
sudo easy_install BeautifulSoup4
Searching for BeautifulSoup4
Best match: beautifulsoup4 4.4.1
Processing beautifulsoup4-4.4.1-py2.7.egg
beautifulsoup4 4.4.1 is already the active version in easy-install.pth
Using /Library/Python/2.7/site-packages/beautifulsoup4-4.4.1-py2.7.egg
Processing dependencies for BeautifulSoup4
Finished processing dependencies for BeautifulSoup4
这样我就无法在python3中使用bs4，如何在python3上安装bs4？
答案 0 :(得分：5)
您应该使用pip3可执行文件：
sudo pip3 install beautifulsoup4
如果您没有安装pip3：
curl bootstrap.pypa.io/get-pip.py | python3
