Pip: 点子列表断言错误

使用http://python-distribute.org/distribute_setup.py脚本安装分发时会发生这种情况。 运行pip install -U distribute可解决此问题。 该错误仅在pip==1.4复制。 这是此行失败的原因：

ipdb> specs
[]

好的，可以解决该问题，但是现在无论何时尝试安装软件包或升级过时的软件包，我都遇到问题。

我已经升级了分发版，也升级了setuptools。

升级分发工作，谢谢！

遇到同样的问题，升级分发版对我也很有效。

pip安装的更多内容-U Distribution

在遇到pip list的AssertionError ，建议的修复pip install -U distribute错误并显示消息“需要dist-info支持的setuptools> = 0.8”。 用法和日志如下。 pip install -U setuptools是否合适？ 我担心自己尝试一下，因为我对pip和依赖项管理的经验不足。 谢谢！

只需运行pip list就可以在最新的Linux Mint（16）上使用pip（1.4.1）的打包版本。 该问题似乎已经很老了，似乎没有尝试修复它。 这个对吗？ 如果是这样，如果我有一些空闲时间，我可能会对此有所了解。

我也在Lubuntu（14.04 LTS）上使用pip == 1.5.4遇到了这个问题。 但是升级分发对我有用！

@jetheurer您能说出遇到错误时使用的发行版吗？

这应该是您应该使用http://packages.ubuntu.com/trusty/python-setuptools的最新setuptools软件包，希望没有任何本身称为分发的软件包（分发已由setuptools替换）。

@Ivoz我目前正在使用Python 2.7.6使用distribute == 0.7.3。 看来我也安装了setuptools == 0.6c11

@jetheurer我不确定使用14.04时如何获得这样的旧版本。 我怀疑旧版本可能会导致您出错。 值得信赖的通常是

不久前，Distribute已合并到setuptools中。 因此，您通常希望使用最新版本的setuptools（几乎所有高于1.0版的东西都可以使用！）。 您可以在这里看到最新版本。

尝试卸载所有发行版/ setuptools（仔细检查！），然后重新安装较新版本是我建议的操作方法。

我已经将pip和sudo apt-get install python-pip ，但是即使是最新的pip ， distribute和setuptools我仍然有AssertionError当使用pip list或pip freeze在Ubuntu 14.10。 命令sudo apt-get install python-pip还会安装依赖项： python-colorama ， python-distlib ， python-html5lib ， python-requests和python-wheel 。 我认为其中一些模块给了我AssertionError ，因此我已将pip的所有依赖项与sudo apt-get remove --auto-remove python-pip卸载，然后仅将pip与sudo easy_install pip一起卸载pip sudo easy_install pip 。 只有这种方式对我有效。

我遵循@arktrin的评论，此问题已解决。
下面是日志。

_Ubuntu 15.04，pip 1.5.6，distribution-0.7.3_中仍然存在此问题（“ pip”或“ distribute”的pip升级不起作用，因为该问题似乎是Ubuntu特有的。请参见下文）。

修复它：

• 删除ubuntu软件包： sudo apt-get remove --auto-remove python-pip
• 下载官方pip安装程序： wget https://bootstrap.pypa.io/get-pip.py
• 通过运行下载的安装程序来安装pip： sudo python get-pip.py
• 添加符号链接以使其在没有完整路径的情况下运行： sudo ln -s /usr/local/bin/pip /usr/bin/pip

做完了！

@UzLA谢谢！ 这在Kubuntu 15.04上也对我有效。 我为此建立了一个盐状态。

@UzLA +1。 删除ubuntu软件包后，我使用easy_install而不是下载官方安装程序，但效果相同：)

@UzLA谢谢，在Lubuntu 15.04 / pip 7.1.0 / python 2.7.9上也帮了我

@UzLA ，只想确认这对我

问题似乎来自过时的发行版和旧的pip版本。
它当然可以关闭。

另外，AssertionError现在在最新版本中更加清晰，因为它现在可以打印出有问题的dist（https://github.com/pypa/pip/blob/develop/pip/__init__.py#L262-L264）
与＃1346相关。

FWIW：我修补了本地安装的点pip 1.5.6 from /usr/lib/python2.7/dist-packages (python 2.7) ，向我展示了令人讨厌的dist。

@arktrin的方法在Ubuntu 15.04中对我

@arktrin的方法也对我

通过apt-get进行pip install将安装一个非常旧的版本。 如果您使用easy_install安装较新版本的pip，则不会收到此错误。

sudo easy_install pip将我的点子版本从1.5.4更新到7.1.2，现在点子对我来说工作正常。

您可能还想更新setuptools sudo pip install setuptools==7.0

这对我有用

@kumardadi也为我工作。

pip软件包的维护者应该确实将一个新版本添加到Ubuntu和Debian软件包存储库中。

我们无法控制发行什么版本的pip Ubuntu和Debian。 如果您想要这些存储库中的较新版本，则需要联系Ubuntu和Debian并要求他们提供。

@dstufft有我可以用来联系他们的任何链接或邮件列表吗？

https://lists.debian.org/debian-python/是他们的邮件列表，但我实际上并不怀疑他们会升级已经发布的Debian / Ubuntu版本。 不幸的是，我们无能为力:(

在Ubuntu的启动板中已提交了有关升级pip的中等优先级错误报告： https :

该错误发布于2015-04-19，但尚未分配...如果幸运的话，我们可能会在Ubuntu 16.04中得到它。

我收到以下错误：

接下来做什么？

@ shruti927

我收到以下错误：

做什么 ？

这似乎与该问题完全无关，所以打开一个新的？
但这看起来像一个简单的权限问题？ 也许您应该使用--user或sudo ？

运行'sudo pip list'
权限被拒绝，因为您没有以root用户身份运行命令

@kumardadi我尝试运行您告诉的命令，然后收到此错误：

当前用户不拥有目录“ /home/shrutika/.cache/pip/http”或其父目录，并且缓存已被禁用。 请检查该目录的权限和所有者。 如果使用sudo执行pip，则可能需要sudo的-H标志

sudo的-H标志是什么，下一步我该怎么做？

运行'sudo -H pip list'，这将解决
-H用于覆盖缓存权限

@ shruti927您使用的是什么版本的pip？

pip-7.1.2和python 2.7.6

谢谢@UzLA ，您的解决方案对我有用！

@UzLA谢谢，对我

好。
