你好，

在virtualenv中，使用python v2.7.1，我无法通过setuptools / distribute的install_requires指令安装numpy。

from setuptools import setup
setup(...
      install_requires=['numpy'],
      ...)

python setup.py install提供了以下回溯：

最有用的评论

作为遇到此问题的任何人的FYI，使用最新版本的setuptools ，一种解决方法是将NumPy添加到setup_requires 。我仍然将其保存在install_requires ，因此我的setup.py看起来像：

setup(
...
    setup_requires=["numpy"],
    install_requires=["numpy"],
)

此方法有效，并且仅在Mac OS X和Linux（未在Windows上测试）上安装NumPy一次。

至于为什么我不知道。

我不确定到底是什么问题，但是可以通过运行先安装numpy然后安装软件包的安装脚本来解决此问题吗？如果可以避免的话，依靠这些不良记录的setuptools功能不是一个好主意。

如果我不得不猜测，我会说第一次调用setuptools.setup（）会调用一堆魔术，为numpy.distutils搞砸了，因此：

Running from numpy source directory.Warning: distutils distribution has been
initialized, it may be too late to add a subpackage commandWarning: distutils
distribution has been initialized, it may be too late to add a subpackage

该警告来自distutils / misc_util.py。

我只是遇到了同样的错误，对我来说，它似乎是由某些依赖关系问题引起的。如果我将easy_install与其他模块一起重试，则它们将第二次运行。我最好的猜测是，easy_install会话结束后，某些依赖项才是“可见的”。

是否有可能在某个时候解决此问题？这会导致应有非IHMO的解决方法。我真的很想达到可以在setup.py的install_requires选项中指定numpy的地步。

prologic 于 2013-11-28

当然，如果有人花时间真正理解问题并提交干净的解决方案，这是可能的。就我个人而言，这不是一件容易的事-应该避免install_requires恕我直言（至少直到pip和easy_install至少在升级软件包时停止升级依赖项为止）。

我刚刚尝试通过在创建的2.7 virtualenv中安装pandas（使用install_requires ）来重现此代码，如下所示：

$ virtualenv --no-site-packages nonumpy
$ source nonumpy/bin/activate
$ cd $PANDAS_DIR
$ pip install cython # needed for pandas
$ python setup.py install

如果有人可以提供一种简单的方法来重现此内容，那将会有所帮助。

我一直试图找出类似的问题，当Numpy的构建通过setup_requires=['Numpy']在Astropy中运行，而Astropy本身作为setup_requires的另一个包装安装时，有时会发生（我称此为“ setupception”）。

我已经将其追溯到这个古老的代码了（但原则上还是有意义的，至少是稍微吗？）： https :

在大多数情况下，运行Numpy的setup.py时，它将configuration的函数推入numpy.distutils.core.setup的kwarg中。 numpy.distutils.core.setup依次将'configuration'键从设置小程序中弹出，然后在distutils.core设置一些“魔术”全局变量，然后递归调用_itself_ 。此递归调用的目的是使用distutils机制检查命令行参数中的错误/-帮助。

然后，它调用configuration函数，该setup()函数，现在所有软件包都已完全配置。

这一切都是在肮脏的地方发生的，是Configuration经理偶尔需要调用get_distribution实用程序，以便将内容附加到Distribution对象。对此的需求是有争议的。事实上，虽然有代码的某些部分Configuration是认为它应该是能够做到这一点，也有认为，如果已经有一个其他地方Distribution例如连接到distutils.core._setup_distribution则可能出了点问题（因此“有人已在该线程中报告了“ distutils发行版已初始化，现在添加子包可能为时已晚”）。

稍作备份并希望澄清一下-从distutils（或setuptools）运行setup()函数时，它将从setup() kwargs初始化Distribution对象，然后分配结果Distribution到全局变量distutils.core._setup_distribution 。实际上，它实际上不会清除此变量，因为它假定将在当前Python解释器中运行的是_only_设置。它不是为设置接收而设计的。（pip通过从自己的子进程安装每个软件包来安装多个软件包时解决了这个问题和类似问题）。但是，在其他情况下，例如setup_requires ，根包中可能已经有一个Distribution实例挂在distutils.core._setup_distribution 。因此，当Numpy的Configuration类试图将_Numpy本身_附加到Distribution对象时，在某些情况下，它可能最终会弄错错误的Distribution 。由于缺少一些位，这会导致Numpy构建混乱。

从setuptools端和/或Numpy端都有许多可能的解决方法。我还没有决定最好的方法是什么，但是整个事情绝对是一团糟:)

embray 于 2015-03-09

值得一提的是，setuptools结束时可能采取的一种解决方法是使用setuptools.sandbox.run_setup ，setuptools用于实现setupception的功能，用于在运行安装程序之前/之后保存/恢复所有distutils.core全局变量有问题的脚本。

碰巧的是，我相信当前版本的setuptools可能已经通过在调用子setup.py脚本之前隐藏了原始的distutils.core （将其从sys.modules删除）来解决此问题。 _应该_照顾它。但是我没有仔细检查。

更新：确认，我上面描述的问题已在大于等于10.0的setuptools中解决（某种程度上是偶然的意外）。

embray 于 2015-03-09

@embray ，这是侦探工作的好地方！（这有点伤了我的头：））

您说对了easy_install -因此我认为get_distribution() -仍然足够相关，以至于我们不应该破坏它。

rgommers 于 2015-03-09

@rgommers事实是，

@embray听起来不错。如果您准备好补丁，并且在约2周内未得到审查，请（认真地）踢我一下

rgommers 于 2015-03-09

setup_requires = [“ numpy”]对我不起作用。我收到此错误消息：

AttributeError：“模块”对象没有属性“ get_include”。

但是第二次运行“ python setup.py install”解决了该问题。另请参见http://stackoverflow.com/questions/21605927/why-doesnt-setup-requires-work-properly-for-numpy

就其价值而言，我从未忘记解决此问题的想法，而现在只需要专注于其他事情。如果有人想偷偷摸摸，我就他们可能去的地方提出了一些高级建议，在此提出了一些意见。

embray 于 2015-07-20

因此，此问题是由于设置了__builtins__.__NUMPY_SETUP__ = True
当您安装需要numpy作为依赖项的依赖项时，setuptools不会重置__NUMPY_SETUP__ 。
看起来您正在尝试在此处设置__NUMPY_SETUP__ = False
https://github.com/numpy/numpy/blob/055056a3108ab19883e50ac125ab9974823498c7/numpy/distutils/misc_util.py#L2195
但此代码从未到达，因为前一行的返回值...

实际上，我相信整个isbootstrapping函数在这里滥用/滥用__builtins__的方式会在您将numpy作为依赖项并且具有以numpy作为依赖项的依赖项时中断。

JensTimmerman 于 2016-08-17

@JensTimmerman我怀疑这也与https://github.com/matplotlib/matplotlib/issues/6928有关，

charris 于 2016-08-19

@rgommers有何想法？

但此代码从未到达，因为前一行的返回值...

is_bootstrapping函数不会在看起来像的任何地方使用，因此无关紧要。

rgommers 于 2016-08-21

实际上，我相信整个isbootstrapping函数在这里滥用/滥用内置函数，这种方式在您将numpy作为依赖项并且具有以numpy作为依赖项的依赖项时会中断。

__builtins__的唯一用途是在此处的主要setup.py 。

这很丑陋，但也很难以更强大的方式编写。我目前的猜测是，如果存在问题，在某些情况下只会以setup_requires='numpy' ，而不会以install_requires 。它们之间的区别在于前者调用setuptools因为pip尚不知道如何处理它。在Scipy中，我们确实使用setup_requires='numpy' ，并且从未遇到过此问题。因此，可能还有matplotlib安装脚本中的时髦功能。

rgommers 于 2016-08-21

通过https://github.com/numpy/numpy/issues/2434#issuecomment -77898051再次阅读，这似乎很好地描述了问题的原因，我认为这与__NUMPY_SETUP__没有任何关系。

编辑：或者也许在某些情况下可以，但是很难用另一种方式来处理。通常，这里没有问题，因为pip设法以一种完全隔离的方式来构建/安装东西。

rgommers 于 2016-08-21

通过在setup.py的末尾使用del builtins.__NUMPY_SETUP__来证明这个理论是对还是错都不应该太难。

万一https://github.com/numpy/numpy/issues/2434#issuecomment -49156521中的要点在某个时候消失了，这里有一个复制此问题的方法：

cd /tmp

cat > ./setup.py <<DELIM
#!/usr/bin/env python

# Author: "Chris Ward" <[email protected]>

from setuptools import setup

default_setup = dict(

    install_requires=['pandas'],
    requires=['pandas'],
    license='GPLv3',

setup(**default_setup)

DELIM


virtualenv --no-site-packages ~/virtenvs/nonumpy

任何帮助，将不胜感激，谢谢

请分享您的requirements.txt

mattip 于 2019-07-02

需求文件包含：

烧瓶== 1.0.2
flask-jwt == 0.3.2
flask-script == 2.0.6
flask-scrypt == 0.1.3.6
PyJWT <1.5.0
眨眼== 1.4
电话号码== 8.9.12
侧翼== 0.9.0
bugsnag == 3.4.3
pickledb == 0.7.2
要求== 2.19.1
python-dateutil == 2.8.0
gunicorn == 19.9.0
gevent == 1.3.6
webargs == 4.0.0
ply == 3.10
bson == 0.5.7
芹菜== 4.2.1
redis == 3.2.1
雷迪斯
numpy == 1.16.4

最后管理它以将numpy保留在需求文件中，并在以后安装熊猫

在Docker中运行命令：

运行pip安装https://github.com/pydata/pandas/releases/download/v0.24.2/pandas-0.24.2.tar.gz

但是，现在编译存在另一个问题，即您需要安装cython来编译熊猫。

错误：

例外：找不到Cython生成的文件'pandas / io / sas / sas.c'。
Cython需要从开发分支编译熊猫。
请安装Cython或下载熊猫发布包。

任何想法？

omeryounus 于 2019-07-02

与此问题无关，该问题与在setup.py使用install_requires setup.py 。请打开新一期。您真的需要从源代码安装熊猫吗？为什么不pip install pandas==0.24.2呢？

mattip 于 2019-07-02

是的，我将在pandas库中打开此问题。但是，由于您无法直接安装熊猫numPy，因此我之前提到的与numPy有关的帖子已正确安装在docker env下的Python2.7上。
为什么不pip install pandas == 0.24.2？因为当我在docker下运行它时会说。

例外：找不到Cython生成的文件“ pandas / msgpack.c”。
Cython需要从开发分支编译熊猫。
请安装Cython或下载熊猫发布包。

所以我需要使用要从tarball安装的熊猫发行版

omeryounus 于 2019-07-02

闭幕。我认为python世界正从setup_requires移到requirements.txt或pyproject.toml 。下面的变通办法是针对仍想使用setup_requires 。

setup(
...
    setup_requires=["numpy"],
    install_requires=["numpy"],
)

至于试图在python2上安装numpy的@omeryounus ，这是一个与此问题无关的单独问题。一些用户报告说，将pip和setuptools升级到最新版本可以解决该问题。

如果还有更多要讨论的地方，请重新打开setup_requires 。
