|
|
101 | ========================================== | |
|
|
102 | ||
|
|
103 | Starting with version 6.0, IPython does not support Python 2.7, 3.0, 3.1, or | |
|
|
104 | 3.2. | |
|
|
105 | ||
|
|
106 | For a version compatible with Python 2.7, please install the 5.x LTS Long Term | |
|
|
107 | Support version. | |
|
|
108 | ||
|
|
109 | If you are encountering this error message you are likely trying to install or | |
|
|
110 | use IPython from source. You need to checkout the remote 5.x branch. If you are | |
|
|
111 | using git the following should work:: | |
|
|
112 | ||
|
|
113 | $ git fetch origin | |
|
|
114 | $ git checkout 5.x | |
|
|
115 | ||
|
|
116 | If you encounter this error message with a regular install of IPython, then you | |
|
|
117 | likely need to update your package manager, for example if you are using `pip` | |
|
|
118 | check the version of pip with:: | |
|
|
119 | ||
|
|
120 | $ pip --version | |
|
|
121 | ||
|
|
122 | You will need to update pip to the version 9.0.1 or greater. If you are not using | |
|
|
123 | pip, please inquiry with the maintainers of the package for your package | |
|
|
124 | manager. | |

134 | This error does also occur if you are invoking ``setup.py`` directly – which you | |
|
|
135 | should not – or are using ``easy_install`` If this is the case, use ``pip | |
|
|
136 | install .`` instead of ``setup.py install`` , and ``pip install -e .`` instead | |
|
|
137 | of ``setup.py develop`` If you are depending on IPython as a dependency you may | |
|
|
138 | also want to have a conditional dependency on IPython depending on the Python | |
|
|
139 | version:: | |
|
|
140 | ||
|
|
141 | install_req = ['ipython'] | |
|
|
142 | if sys.version_info[0] < 3 and 'bdist_wheel' not in sys.argv: | |
|
|
143 | install_req.remove('ipython') | |
|
|
144 | install_req.append('ipython<6') | |
|
|
145 | ||
|
|
146 | setup( | |
|
|
147 | ... | |
|
