Python Pip 安装“Egg”错误（Pandas 和其他模块）

Question

安装某些 python 模块（例如 pandas）时遇到问题，安装 ipython 笔记本时也遇到一些问题。

其他人似乎以前也出现过此错误（Python pip install 失败：无效命令 Egg_info），但他们使用的是 Python 2.7，而我使用的是 2.6（默认情况下我的 Mac OS 10.6）。我还尝试了 easy_install -U setuptools 和 pip install --upgrade setuptools 但都不起作用。

这是我安装 pandas 时遇到的错误：

Command python setup.py egg_info failed with error code 1 in /private/var/folders/Wm/WmmbYincEnuCrAMtGBudAk+++TM/-Tmp-/pip_build_AWal/pandas
Storing debug log for failure in /Users/AWal/Library/Logs/pip.log

安装 iPython 时，这是我收到的错误：

有什么想法要做什么吗？

更新：

当我执行 sudo pip install pandas （另一个我无法安装的模块）时，我收到一条很长的回溯，并带有最终错误消息：

RuntimeError: Broken toolchain: cannot link a simple C program

回溯（大约 100 行的样本）如下所示：

Traceback (most recent call last):

Answer 1

权限被拒绝消息会建议您按照 Hackaholic 的建议以 root 身份运行命令。 试试

sudo pip install YOUR_PACKAGE

您可能还想查看

virtualenv

以使用更隔离的环境。 在基于 debian 的发行版下，您可以使用

apt-get install python-virtualenv

安装 python-virtualenv 软件包。

然后通过键入

virtualenv whatever

创建一个虚拟环境名称（这将在当前文件夹中创建一个文件夹

whatever

）。 然后

cd

并输入 bin/activate 进入这个虚拟环境。 从那里再次尝试您的

pip install

命令。

可能有帮助

更新： 您可以尝试使用此处

提供的建议解决方案

总而言之，尝试在

export ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future

 中添加 

~/.bash_profile

Answer 2

这个问题在谷歌中排在第一位，但第二个实际上有效：

pip install -U setuptools

pip install ez_setup
