运行'pip install -r requirements.txt --upgrade'时出错 [英] Error when running 'pip install -r requirements.txt --upgrade'

问题描述

当我在Django项目中运行以下命令时:

When i run following command in my Django project:

pip install -r requirements.txt --upgrade

pip install -r requirements.txt --upgrade

我收到以下错误:

检测到一个无法安装的distutils安装项目("argparse"). distutils提供的元数据不包含 已安装文件的列表，因此pip不知道哪个 要卸载的文件.

Detected a distutils installed project ('argparse') which we cannot uninstall. The metadata provided by distutils does not contain a list of files which have been installed, so pip does not know which files to uninstall.

我的requirements.txt文件如下:

My requirements.txt file is as follow:

Django==1.8.1

pycrypto==2.6.1
Pillow==2.4.0

我的点子版本是点子8.0.0，我正在使用ubuntu.任何人都可以帮助解决问题吗?

My pip version is pip 8.0.0 and I am using ubuntu. Can any one help to resolve issue?

推荐答案

如果您使用的是virtualenv，则不应该这样做，如果确实如此，那么这与您的问题类似.

If you're using a virtualenv, this shouldn't happen,if it does, then here is a similar question to your problem.

OS X卸载distutils已安装项目

如果您确实删除了argparse软件包，则可以使用pip再次安装它.

If you do remove the argparse package, it can be installed again using pip.
