安装 Django-channels 错误

Question

I'm trying to develop a chat application in Django on mac OS. I've tried to install Django-Channels in virtualenv, with this commands:

pip install channels

pip install django-channels

but this error occurred:

Command "python setup.py egg_info" failed with error code 1 in /private/var/folders/4c/xy3rtg_165l0650j4tq7fvrh0000gn/T/pip-install-7anqvzhg/twisted/

Python version = 3.5.2,
Django version = 1.11,
pip is already up-tp-date

Answer 1

当我安装 Visual C++ 构建工具时，问题解决了。

Answer 2

this worked for me if you are using mac

xcode-select --install

Answer 3

我认为如果您更新了 pip，您的问题将得到解决

Answer 4

Had similar problem, and this fixed it.

Inside of virtual environment,

pip install incremental then pip install channels

you can check that it worked by running

python3 -c 'import channels; print(channels.__version__)'

Answer 5

Looks like you have outdated version of setup tools. try:

pip install --upgrade setuptools
