Question

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

此错误似乎已经出现在其他人（Python pip install fails: invalid command egg_info）之前，但是他们使用的是Python 2.7，而我使用的是2.6（默认使用我的Mac OS 10.6）。我也试过easy_install -U setuptools和pip install --upgrade setuptools但是都没有用。

这是我安装pandas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：

Exception:

有关该怎么做的任何想法？

更新：

当我做sudo pip安装pandas（我无法安装的另一个模块）时，我会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

并且追溯（大约100行的样本）如下所示：

Traceback (most recent call last):

Answer 1

权限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的发行版中，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到它并键入bin / activate以进入此虚拟环境。从那里再次尝试pip install命令。

可能会有帮助

更新：您可以尝试使用建议的解决方案here

总结一下，尝试在export ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future

中添加~/.bash_profile
