| 100 | IPython requires Python version 3 or above |
|
|||
| 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 | ... |
|
|||
| 148 | install_requires=install_req |
|
|||
| 149 | ) |
