Question

我尝试通过pip安装python软件包，这会在setup.py中引发SyntaxError：

$ /usr/bin/pip install dash --user
DEPRECATION: Python 2.6 is no longer supported by the Python core team, please upgrade your Python. A future version of pip will drop support for Python 2.6

    Complete output from command python setup.py egg_info:

    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-ysGuJO/dash/
You are using pip version 7.1.0, however version 18.0 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

我在这里做错了什么？我想它与一个过旧的python版本有关：

$ python --version
Python 2.6.6

因为响应类似于this, more specific question on stackoverflow和

pip install urllib3

工作正常，只需要> = Python 2.6。

Answer 1

这是一个问题，因为python版本较旧。您可能需要升级python。升级后，您将不会遇到任何问题。下面是升级步骤。在您的终端中编写步骤。

a = ['Fri, 19 Aug 2011 19:28:17 -0000',....., 'Wed, 05 Feb 2012 11:00:00 -0000']

Answer 2

apt-get update
apt-get install python python-pip
python -m pip install --no-cache-dir setuptools==20.7.0
python -m pip install xxx

为什么“ pip install”会在setup.py中引发SyntaxError？
