我在安装过程中看到Django代码中的语法错误。

修改

修复easy_install问题后，我看到同样的错误，

目前使用pip3方法并安装了django

问题：

这种语法错误会被忽略吗？

Answer 1

使用apt-get在Ubuntu上安装pip

对于python3

sudo apt-get install python3-pip

然后安装django不会没问题

在python3中安装django

pip3 install django

如果你已经有py3.6那么

wget https://bootstrap.pypa.io/get-pip.py
sudo python3.6 get-pip.py
sudo ln -s /usr/bin/python3.6 /usr/local/bin/python3
sudo ln -s /usr/local/bin/pip /usr/local/bin/pip3

然后用py3.6安装Django

python3.6 -m pip install django

Django安装 - 语法错误
