Question

尝试使用pipenv时有点麻烦。我运行了以下命令

pipenv安装bs4

它出来了：

���������������������������������Requirement already satisfied: bs4 in /home/sam/.local/share/virtualenvs/ICOtools-kKWO0fqD/lib/python2.7/site-packages
Requirement already satisfied: beautifulsoup4 in /home/sam/.local/share/virtualenvs/ICOtools-kKWO0fqD/lib/python2.7/site-packages (from bs4)

Adding bs4 to Pipfile's [packages]���
Locking [dev-packages] dependencies���
Locking [packages] dependencies���
Updated Pipfile.lock (5de6ca)!

然后当我运行我的脚本时，我仍然得到

'ImportError: No module named bs4'

我脚本的第二行是

'from bs4 import BeautifulSoup'

我正在使用crouton在chromebook上运行Ubuntu（xenial），不确定是否会影响它。

Answer 1

而不是pipenv install bs4

尝试pipenv install beautifulsoup4

Answer 2

我相信你没有激活你的虚拟环境。默认情况下，当您运行pipenv install bs4时，会创建virtualenv。您可以从同一目录运行pipenv shell以激活它（并exit停用）。 EX：

ubuntu@ubuntu-zesty:~$ pipenv install bs4
Installing bs4…
Collecting bs4
Collecting beautifulsoup4 (from bs4)
  Using cached beautifulsoup4-4.6.0-py2-none-any.whl
Installing collected packages: beautifulsoup4, bs4
Successfully installed beautifulsoup4-4.6.0 bs4-0.0.1

Adding bs4 to Pipfile's [packages]…

Locking [packages] dependencies…
Updated Pipfile.lock (9e60b9)!
ubuntu@ubuntu-zesty:~$ pipenv shell
Spawning environment shell (/bin/bash). Use 'exit' to leave.

>>> import bs4
