Question

我正在尝试在AWS EC2计算机上使用名为csvkit的Python包。我可以在一些打嗝之后安装它，这可能是相关的 - 运行pip install csvkit引发错误

with open(path, 'rb') as stream:
    IOERROR: [Errno 13] Permission denied: '/usr/local/lib/python2.7/site-packages/python_dateutil-2.2-py2.7.egg/EGG-INFO/requires.txt'

但我可以用其他命令安装它。

现在解决原始问题 - 当我尝试在csvkit包中运行一个简单的函数，如cavstat时，这是完整的错误输出：

[username ~]$ csvstat

    return yield_lines(self.get_metadata(name))
  File "/usr/lib/python2.7/dist-packages/pkg_resources/__init__.py", line 1581, in get_metadata
    return self._get(self._fn(self.egg_info, name))
  File "/usr/lib/python2.7/dist-packages/pkg_resources/__init__.py", line 1692, in _get
    with open(path, 'rb') as stream:
IOError: [Errno 13] Permission denied: '/usr/local/lib/python2.7/site-packages/python_dateutil-2.2-py2.7.egg/EGG-INFO/requires.txt'

我不确定甚至可以搜索什么来查看问题。这与date-utils有关吗？我对Linux世界还不熟悉，所以编辑配置文件对我来说有点困难。

如果您通过'pip install csvkit'进行系统范围的安装，那么您将需要为当前用户提供sudo权限，这就是为什么安装过程已经开始修改/ usr / local / lib / python2 .7结构。

如果您使用的是自己创建的AWS实例，则可以非常简单地为当前用户设置sudo权限。

如果您正在寻找更多包含的替代方案，您可以安装virtualenv并设置一个隔离的virtualenv（https://virtualenv.pypa.io/en/latest/installation.html），但virtualenv对于一次性服务器可能过度。

这有帮助吗？
