由于 python 路径，命令行工具授予权限被拒绝

Question

我使用的是 Ubuntu，并通过文档中记录的命令安装了 bigquery 命令行工具：“easy_install bigquery”（不带引号 - 另请参阅 https://developers.google.com/bigquery/bq-command-line-tool#installation） - 因为对python2.7路径，我不得不将命令更改为“sudo easy_install bigquery”。

现在每次我尝试从命令行运行命令“bq”时，都会收到以下错误：“IOError: [Errno 13] Permission denied: '/usr/local/lib/python2.7/dist-packages/ bigquery-2.0.14-py2.7.egg/EGG-INFO/requires.txt'"

如果我使用命令“sudo bq”运行它，它运行良好，但我想运行 bigquery 而不必将它作为 sudo 运行。我确定我做错了什么，但我不知道是什么。有什么建议吗？

这是完整的跟踪：

谢谢，

检查/usr/local/lib/python2.7/dist-packages/bigquery-2.0.14-py2.7.egg 和子文件夹的权限。

我知道这可能晚了一年，但我找到了解决方案；基本上，您必须以“root”管理员身份登录才能访问可以在 Linux 操作系统中编辑任何内容的点。为此，您必须在您的 vps 帐户（您的普通帐户）上登录您的终端，然后发出命令

“sudo passwd root”。

这将提示您使用密码创建一个 root 帐户（在其他 ubuntu 版本上可能会有所不同）。然后要访问您创建的这个“root”帐户，您需要重新启动 PC，打开终端，然后发出命令

“su”

以 root 用户身份登录；使用“sudo”来执行命令。
