添加解释器时Pycharm错误，权限被拒绝

Question

在添加解释器时，我在 pycharm 上获得了权限被拒绝。它曾经工作过，突然坏了，不知道发生了什么变化。它在 pycharm 2.7.3 上坏了，我升级到 3.0 但仍然坏了。添加了 interpeted 但它会引发此错误。任何信息都会很有用。我认为安装虚拟环境后它可能会损坏（不确定）

路径没问题，但是包是空的，安装按钮是灰色的。通常我通过终端安装，但无论如何让 ide 完全工作会很好。

更新

哪个python->/usr/bin/python

更新 2 我发现有些egg文件有不同的权限。 当我将权限更改为 rw r r (644) 时，由于某种原因，它们又回到了 600。

umask -> 0022

Answer 1

我设法解决了。

1. 我发现 1 个特定的 egg (python_dateutil-2.1-py3.3.egg) 对于非 linux 用户的权限不正确 (600)，这意味着只有管理员才能读取该文件。
2. 我更改了权限（改为644）并重新添加了解释器。权限自动返回到600。 Umask 很好(022) 所以我认为 pycharm 改变了它。
3. 我做了sudo pip install --upgrade python-dateutil 并再次将权限更改为644。
4. 然后它起作用了。我认为 pycharm 不喜欢 pkg 的某些内容。

点输出：

sudo   pip install --upgrade python-dateutil

Answer 2

我在安装 Java Development Kit 和 Eclipse 后遇到了这个问题。我修复它的方法是从控制面板卸载 jdk 并重新安装 Python 3.2 确保我添加了新的路径名。我还删除了以前链接的 PATH 变量到 Python。
