烧瓶安装不能正常工作 [英] Flask installation doesn't work properly

问题描述

我正在使用Merverick OSX。我已经安装Python 3.3.3进入我的电脑，我想安装Flask

当我在终端中键入这个

  $ sudo easy_install virtualenv 
  

终端显示此错误我

 错误：无法创建或删除安装目录中的文件
 
发生以下错误试图添加或删除
安装目录中的文件：
 
 [Errno 13] Permission denied：'/Library/Python/2.7/site-packages/test-easy-install- 
 373.write-test'
 
您指定的安装目录（通过--install-dir，--prefix或
 distutils默认设置）为：
 
 /Library/Python/2.7/site-packages/ 
 
也许您的帐户没有对此目录的写入权限？如果
安装目录是系统拥有的目录，则可能需要以管理员或root帐户登录
。如果您没有管理员
访问此计算机，则可能希望选择不同的安装
目录，最好是您的PYTHONPATH环境
变量中列出的一个目录。 
 
有关其他选项的信息，您可以参考
文档：
 
 http://peak.telecommunity.com/EasyInstall.html 
 
请为您的系统进行相应的更改，然后重试。 
  

所以我以root用户身份访问，然后键入

  $ sudo easy_install virtualenv 
  

这个，但是有一个关于* .egg的警告是什么？出了什么问题？以及如何解决它？

解决方案

每当我们遇到任何事情时，我们都不能这样做，我们应该阅读讲解的细节
是否找到WARNING ，它告诉你这不是错误;和

 已安装/Library/Python/2.7/site-packages/virtualenv-1.10.1-py2.7.egg 
为virtualenv处理依赖关系
完成对virtualenv的处理依赖关系
  

说实话的是，已成功安装virtualenv。
现在你可以根据Flask给出的文档，学习Flask;

I'm using Merverick OSX. I have installed Python 3.3.3 Into my computer and I would like to install Flask

When I type this in terminal

$sudo easy_install virtualenv

terminal shows this error to me

error: can't create or remove files in install directory

The following error occurred while trying to add or remove files in the
installation directory:

[Errno 13] Permission denied: '/Library/Python/2.7/site-packages/test-easy-install-    
373.write-test'

The installation directory you specified (via --install-dir, --prefix, or
the distutils default setting) was:

/Library/Python/2.7/site-packages/

Perhaps your account does not have write access to this directory?  If the
installation directory is a system-owned directory, you may need to sign in
as the administrator or "root" account.  If you do not have administrative
access to this machine, you may wish to choose a different installation
directory, preferably one that is listed in your PYTHONPATH environment
variable.

For information on other options, you may wish to consult the
documentation at:

http://peak.telecommunity.com/EasyInstall.html

Please make the appropriate changes for your system and try again.

So I have access as root user and then type

$sudo easy_install virtualenv

and it says like this but there is a warning about *.egg what is that? something goes wrong? and how to fix it?

解决方案

Every time when we meet anything we cannot undestand like this, we should read the explainin detail。 did you find the "WARNING", it tell you it's not error; and

  Installed /Library/Python/2.7/site-packages/virtualenv-1.10.1-py2.7.egg    
  Processing dependencies for virtualenv
  Finished processing dependencies for virtualenv

tell the truth is that you have installed virtualenv successfully. Now you can according the docs given by Flask, learn Flask;
