我使用的是Ubuntu 14.04和Python 3.5;我使用<?php
$files = glob("images/*.png");
$current = file_get_contents("current.txt");
if (count($files) <= $current) {
$current = 1;
} else {
$current++;
}
$im = imagecreatefrompng("images/".$current.".png");
header('Content-Type: image/png');
imagepng($im);
imagedestroy($im);
file_put_contents("current.txt", $current);
?>
来安装quandl包。我看到下面的错误。
另一方面，我尝试了两种方法：
下载.whl包并提供.whl文件所在的路径。我看到同样的错误如下。
pip install quandl我试过的其他方法是使用Processing ./Documents/Quandl-3.2.0-py2.py3-none-any.whl

。使用此方法时，我看到下面的错误
sudo -apt get install python -3 quandl对于方法1：我无法理解为什么我收到权限被拒绝错误消息。
对于方法2：为什么无法找到包？
我将非常感谢您对这些错误消息的任何建议以及在ubuntu 14.04中在python 3.5上安装此软件包的任何帮助。
