Python Pip 安装“Egg”错误（Pandas 和其他模块）

Question

在安装一些 python 模块（例如 pandas）时遇到问题，并且在安装 ipython notebook 时遇到了一些问题。

其他人 (Python pip install fails: invalid command egg_info) 之前似乎出现过此错误，但他们使用的是 Python 2.7，而我使用的是 2.6（默认使用我的 Mac OS 10.6）。我也尝试了 easy_install -U setuptools 和 pip install --upgrade setuptools 但都没有奏效。

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

对于安装 iPython，这是我得到的错误：

有什么想法吗？

更新：

当我执行 sudo pip install pandas（另一个我无法安装的模块）时，我得到一个很长的回溯，并带有结束错误消息：

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 以使用更加孤立的环境。 在基于 debian 的发行版下，您可以使用 apt-get install python-virtualenv 安装 python-virtualenv 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 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： 您可以尝试使用建议的解决方案here

总而言之，尝试在~/.bash_profile 中添加export ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future

这个问题首先出现在 Google 中，但 second 确实有效：

pip install -U setuptools

pip install ez_setup
