我是Python的新手,并且一直在尝试安装一些软件包pip.

但是pip install unroll给了我

命令"python setup.py egg_info"失败,错误代码1在C:\ Users\MARKAN~1\AppData\Local\Temp\pip-build-wa7uco0k\unroll \

我怎么解决这个问题？

当我尝试通过其中的任何一个或通过从他们的站点下载包并运行来安装Python 的Cryptography包时,我收到以下错误:pip install cryptographypython setup.py

无论我正在尝试安装哪个软件包,我都会收到此错误:

error: invalid command 'egg_info'

----------------------------------------
Cleaning up...
Command python setup.py egg_info failed with error code 1 in c:\users\zorpix\appdata\local\temp\pip-build-Zorpix\virtualenv
Storing complete log in C:\Users\Zorpix\pip\pip.log

我看到了这个问题,但答案对我不起作用.我可以安装分发包,到目前为止是我可以安装的唯一软件包,但它不能解决问题,因为我尝试安装另一个软件包后会立即返回egg_info错误.我对此感到非常沮丧,因为我在任何地方都找不到任何有用的东西.我也有django和pip以及之前安装的所有东西,但我不得不重新安装所有,现在它不能正常工作......任何帮助都将不胜感激.

这是它存储的日志:

我试图为教程安装postgres,但是pip给了我错误:

pip install psycopg

我得到一个错误:

Error: pg_config executable not found.

Please add the directory containing pg_config to the PATH

or specify the full executable path with the option:

    python setup.py build_ext --pg-config /path/to/pg_config build ...

or with the pg_config option in 'setup.cfg'.

pg_config我的virtualenv 在哪里？如何配置？我正在使用virtualenv,因为我不想在系统范围内安装postgres.

pip install Twisted在Mac osx 10.9.4上使用virtualenv时,我得到了这个结果:

我不知道该如何解决.我使用了easy_install,但是我遇到了SSL验证问题.有人有类似的问题吗？其余的错误消息如下.

我正在使用python3,我正在尝试在Ubuntu上安装" cairocffi ".为此,我已成功安装:

1. 蟒蛇-dev的
2. libffi-dev的
3. CFFI

但是当我试图安装"cairocffi"时pip install cairocffi,我得到了:

每次我尝试部署到Heroku时,我都会收到一个类似于这个问题的错误(Python pip安装失败:无效命令egg_info)如何解决此问题？它刚刚开始是一个恼人的事情,它会在第二次推动时消失,但现在我根本无法推动.

我的requirements.txt文件.注意:我已经尝试过尝试放入'setuptools'并将其删除,但它没有改变任何东西.

我正在使用Centos 7和Python 2.7.5.问题是当我安装Pandas时,我收到此错误消息

SystemError: Cannot compile 'Python.h'. Perhaps you need to install python-dev|python-devel.

我已经尝试了很多解决方案但是没有成功yum -y update.

• 由于egg_info错误,无法通过pip安装
• Python pip安装失败:命令egg_info无效
• https://www.digitalocean.com/community/tutorials/how-to-set-up-python-2-7-6-and-3-3-3-on-centos-6-4
• pip无法安装任何东西,错误:无效命令'egg_info'

yolk -U最近运行我注意到pip需要从1.2.1升级到1.4.1并且尽职尽责地尝试升级它

pip install --upgrade pip

虽然yolk -U再次运行似乎确认升级成功(pip不再列为过时),但这会生成错误消息
