Question

使用setuptools == 27.2.0，我们的picca软件包（https://github.com/igmhub/picca）的travis测试效果很好。使用最新版本的setuptools == 41.0.0：https://github.com/igmhub/picca/issues/591不再是这种情况。

该问题似乎与setuptools尝试读取脚本的位置有关。我收到以下错误：

Traceback (most recent call last):
  File "/home/travis/virtualenv/python3.6.3/bin/picca_deltas.py", line 4, in <module>
    __import__('pkg_resources').run_script('picca==4.0', 'picca_deltas.py')
  File "/home/travis/virtualenv/python3.6.3/lib/python3.6/site-packages/pkg_resources/__init__.py", line 666, in run_script
    self.require(requires)[0].run_script(script_name, ns)
  File "/home/travis/virtualenv/python3.6.3/lib/python3.6/site-packages/pkg_resources/__init__.py", line 1437, in run_script
    .format(**locals()),
pkg_resources.ResolutionError: Script 'scripts/picca_deltas.py' not found in metadata at '/home/travis/build/igmhub/picca/py/picca.egg-info'

当寻找路径/home/travis/build/igmhub/picca/py/picca.egg-info/时，实际上没有scripts文件夹。我们的python设置如下，我们应该更改一些内容，以便设置工具知道在哪里找到脚本？

#!/usr/bin/env python

import glob

from setuptools import setup

scripts = glob.glob('bin/*')

description = "Package for Igm Cosmological-Correlations Analyses"

version="4.0"
setup(name="picca",
    version=version,
    description=description,
    url="https://github.com/igmhub/picca",
    author="<***>",
    author_email="<***>",
    packages=['picca','picca.fitter2'],
    package_dir = {'': 'py'},
    package_data = {'picca': ['fitter2/models/*/*.fits']},
    install_requires=['numpy','scipy','iminuit','healpy','fitsio',
        'llvmlite','numba','h5py','future','setuptools'],
    test_suite='picca.test.test_cor',
    scripts = scripts
)

命令/home/travis/virtualenv/python3.6.3/bin/picca_deltas.py在我的计算机上如下所示：

#!<where is python>/python/3.6.3/bin/python
# EASY-INSTALL-SCRIPT: 'picca==4.0','picca_deltas.py'
__requires__ = 'picca==4.0'
__import__('pkg_resources').run_script('picca==4.0', 'picca_deltas.py')

感谢您的帮助。

这是一个疯狂的镜头，但我只是遇到了同样的问题。

看看/home/travis/build/igmhub/picca/py/picca.egg-info看起来像您的构建文件夹。它不应该查看build文件夹中的egg-info信息，而是要查看您安装的那个信息。

只需更改目录，就可以了：

cd .. # or cd anywhere outside your build folder
picca_deltas.py

应该工作正常。

我找到了一个修复程序，现在我使用pytest而不是python setup.py test运行测试。 https://github.com/igmhub/picca/pull/698/files。线索在以下消息中；

WARNING: Testing via this command is deprecated and will be removed in a future version. Users looking for a generic test entry point independent of test runner are encouraged to use tox.

python setup.py安装不适用于最新的setuptools：'<*>。egg-info'
