解决方案

您可以放心的忽略警告然而，这个错误：

错误：无法创建'/usr/local/lib/python2.7/dist-packages/flask'：权限被拒绝

告诉我，您正试图将其安装到您的全局系统Python中。没有错，但如果你想这样做，你需要用提升的权限运行命令（使用 sudo ）。

最好使用虚拟环境，以免污染系统范围的Python安装。

使用虚拟环境：

  $ virtualenv flask_env 
 $ source flask_env / bin / activate 
（flask_env）$ pip install Flask 
  

你应该安装virtualenv二进制文件先用 sudo apt-get install python-virtualenv

I'm trying ot install Flask, but I'm betting all these warnings and errors:

Any suggestions to solve this problem?

解决方案

The warnings you can safely ignore; however this error:

error: could not create '/usr/local/lib/python2.7/dist-packages/flask': Permission denied

Tells me that you are trying to install this in to your global system Python. Nothing wrong with that, but if you want to do that you need to run the command with elevated privileges (using sudo).

It is better to use a virtual environment so that you don't pollute the system-wide Python install.

Using a virtual environment:

$ virtualenv flask_env
$ source flask_env/bin/activate
(flask_env) $ pip install Flask

You should probably install the virtualenv binaries first with sudo apt-get install python-virtualenv
