我在Python方面只有非常基础的经验。 我正在尝试安装包pyslim
(请参见这里的pypi网站)。 我已经...
$ pip install pyslim
Requirement already satisfied: pyslim in ./Library/Python/2.7/lib/python/site-packages/pyslim-0.1-py2.7.egg (0.1)
Requirement already satisfied: msprime in /usr/local/lib/python2.7/site-packages (from pyslim) (0.6.1)
Requirement already satisfied: attrs in /usr/local/lib/python2.7/site-packages (from pyslim) (16.3.0)
Requirement already satisfied: svgwrite in /usr/local/lib/python2.7/site-packages (from msprime->pyslim) (1.1.12)
Requirement already satisfied: jsonschema in /usr/local/lib/python2.7/site-packages (from msprime->pyslim) (2.6.0)
Requirement already satisfied: six in /usr/local/lib/python2.7/site-packages (from msprime->pyslim) (1.10.0)
Requirement already satisfied: numpy>=1.7.0 in /usr/local/lib/python2.7/site-packages/numpy-1.10.4-py2.7-macosx-10.11-x86_64.egg (from msprime->pyslim) (1.10.4)
Requirement already satisfied: h5py in /usr/local/lib/python2.7/site-packages (from msprime->pyslim) (2.8.0)
Requirement already satisfied: pyparsing>=2.0.1 in /usr/local/lib/python2.7/site-packages (from svgwrite->msprime->pyslim) (2.2.0)
Requirement already satisfied: functools32; python_version == "2.7" in /usr/local/lib/python2.7/site-packages (from jsonschema->msprime->pyslim) (3.2.3.post2)
但是当我打开python并尝试导入pyslim
时,它失败了。
> import pyslim
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/Users/remi/Library/Python/2.7/lib/python/site-packages/pyslim-0.1-py2.7.egg/pyslim/__init__.py", line 4, in <module>
from pyslim.slim_metadata import * # NOQA
File "/Users/remi/Library/Python/2.7/lib/python/site-packages/pyslim-0.1-py2.7.egg/pyslim/slim_metadata.py", line 1, in <module>
import attr
ImportError: No module named attr
所以,我做了。
$ pip install attr
Requirement already satisfied: attr in /usr/local/lib/python2.7/site-packages (0.3.1)
and$ pip install attrs
Requirement already satisfied: attrs in /usr/local/lib/python2.7/site-packages (16.3.0)
我重新启动了Python并尝试再次导入pyslim
,但仍然收到相同的错误消息。我还尝试通过执行从github下载和安装文件的操作来解决问题。
$ git clone https://github.com/tskit-dev/pyslim.git
$ cd pyslim
$ python setup.py install --user
如此处在pypi网站上所示。在这段代码的最后一行,我得到了以
结尾的一长串输出。Download error on https://pypi.python.org/simple/: [SSL: TLSV1_ALERT_PROTOCOL_VERSION] tlsv1 alert protocol version (_ssl.c:590) -- Some packages may not be found!
No local packages or download links found for attrs
error: Could not find suitable distribution for Requirement.parse('attrs')
我正在使用MAC OSX 10.11.6上的Python 2.7.10。不确定是否重要,但我通常使用homebrew安装东西。我使用的是pip 18.1自/usr/local/lib/python2.7/site-packages/pip(python 2.7)。$ which python
/usr/bin/python
$ which pip
/usr/local/bin/pip
which python
和which pip
。 - deadvoidexport PYTHONPATH=$PYTHONPATH:/usr/local/lib/python2.7/site-packages
- Swagga Tingpip uninstall attr && pip uninstall attrs
pip install attrs
