DistutilsOptionError：必须提供家庭或前缀/ exec-前缀 - 而不是两者 [英] DistutilsOptionError: must supply either home or prefix/exec-prefix -- not both

问题描述

对于Google App Engine，我需要将软件包安装到另一个目标目录。

我试过了：

pip install -I flask-restful --target ./lib

但它失败：

必须提供家庭或前缀/ exec-prefix - 不是两者都不是

我怎样才能使这工作？

解决方案

您是否使用OS X和Homebrew？ Homebrew python页面 https://github.com/Homebrew /brew/blob/master/docs/Homebrew-and-Python.md 使用pip和解决方法调用了一个已知问题。

为我工作。

你可以通过添加一个
〜/ .pydistutils.cfg文件来使这个空前缀成为默认值内容：

  [安装] 
前缀= 
   

编辑：不要使用这个Homebrew推荐选项，它会破坏正常的点操作 em>。

I've been usually installed python packages through pip.

For Google App Engine, I need to install packages to another target directory.

I've tried:

pip install -I flask-restful --target ./lib

but it fails with:

must supply either home or prefix/exec-prefix -- not both

How can I get this to work?

解决方案

Are you using OS X and Homebrew? The Homebrew python page https://github.com/Homebrew/brew/blob/master/docs/Homebrew-and-Python.md calls out a known issue with pip and a work around.

Worked for me.

You can make this "empty prefix" the default by adding a ~/.pydistutils.cfg file with the following contents:

[install]
prefix=

Edit: Do not use this Homebrew recommended option, it will break normal pip operations.
