试图运行一个Python包权限被拒绝 [英] Permission Denied while trying to run a Python package

问题描述

我想要一个AWS EC2计算机上使用一个名为 csvkit Python包。我可以一些麻烦，这可能与后安装 - 运行 PIP在

I'm trying to use a Python package called csvkit on an AWS EC2 machine. I was able to install it after some hiccups, which might be related - running pip install csvkit threw an error at

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'

不过，我能够与其他一些命令来安装它。

But I was able to install it with some other command.

现在到了原来的问题 - 当我尝试运行 csvkit 包像在一个简单的功能cavstat ，这是完全错误输出：

Now onto the original problem - when I try to run a simple function within the csvkit package like cavstat, this is the full error output:

[username ~]$ csvstat

我不知道是什么，甚至搜索，看看有什么问题。这是关系到日期-utils的？ 我是相当新的Linux世界，所以编辑配置文件和诸如此类的东西是有点为难我。

I'm not sure what to even search to see what's the issue. Is this related to date-utils? I'm fairly new to the Linux world, so editing configuration files and whatnot is a bit difficult for me.

推荐答案

如果你正在做一个全系统通过PIP安装csvkit安装，你需要sudo的权限，为当前用户，这也是为什么安装过程borked上修改/usr/local/lib/python2.7结构。

If you're doing a system-wide install via 'pip install csvkit', you'll need sudo privileges for the current user, which is why the install process has borked on modifying the /usr/local/lib/python2.7 structure.

如果你在你已经创建了一个AWS实例，sudo的权限应该是pretty的简单的设置是当前的用户。

If you're on an AWS instance you've created, sudo privileges should be pretty straightforward to set up for your current user.

如果你正在寻找一个更包含的替代方案，你可以安装的virtualenv并成立一个独立的virtualenv（的 https://virtualenv.pypa.io/en/latest/installation.html ），但的virtualenv可能是矫枉过正暴殄天物服务器。

If you're looking for a more contained alternative, you could install virtualenv and set up an isolated virtualenv (https://virtualenv.pypa.io/en/latest/installation.html) but virtualenv might be overkill for a throwaway server.
