我正在尝试将qutebrowser与Tox一起安装，并按照this页上的说明进行操作。 但是，这没有用。当我跑步时
python3 -m qutebrowser
我收到一条错误消息
Fatal error: jinja2 is required to run qutebrowser but could not be imported! Maybe it's not installed?
The error encountered was:
No module named 'jinja2'
Please search for the python3 version of jinja2 in your distributions packages, or see https://github.com/qutebrowser/qutebrowser/blob/master/doc/install.asciidoc
If you installed a qutebrowser package for your distribution, please report this as a bug.
，或者用PyYAML/yaml代替jinja2。
但是，如果我跑步
sudo pip install jinja2
sudo pip install pyyaml
我明白了
Requirement already satisfied: jinja2 in /usr/local/lib/python2.7/dist-packages (2.10.1)
Requirement already satisfied: MarkupSafe>=0.23 in /usr/lib/python2.7/dist-packages (from jinja2) (0.23)
Requirement already satisfied: pyyaml in /usr/local/lib/python2.7/dist-packages (5.1)
我想问题可能是安装的版本是针对python2.7的，但是我遵循了these的说明而未做任何更改。
答案 0 :(得分：0)
您对那些指令进行了更改：您运行python3而不是python。
如果同时安装了Python 2.7和Python 3来安装Python 3软件包，则需要运行pip3 install或python3 -m pip install。
