python - 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 上的权限被拒绝。它曾经工作，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 但它抛出此错误。任何信息都会有用。我认为它可能会在安装虚拟环境后崩溃(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

which python ->/usr/bin/python

更新 2 我发现一些 egg 文件有不同的权限。 当我将权限更改为 rw r r (644) 时，由于某种原因它们会返回到 600。

umask -> 0022

Answer 1

我设法解决了它。

1. 我发现 1 个特定的 egg (python_dateutil-2.1-py3.3.egg) 对于非 linux 用户有不正确的权限 (600) 这意味着只有管理员可以阅读文件。
2. 我更改了权限(到 644)并重新添加了解释器。权限自动返回到 600。 Umask 很好(022) 所以我假设 pycharm 改变了它。
3. 我执行了 sudo pip install --upgrade python-dateutil 并将权限再次更改为 644。
4. 然后成功了。我假设 pycharm 不喜欢 pkg 的某些内容。

点输出:

sudo   pip install --upgrade python-dateutil
