Shaun Overton's questions

我正在尝试使用 pip 在我的 virtualenv 中安装各种要求，但我无法绕过错误Segementation fault (core dumped)。该错误似乎表明内存访问问题，但我不明白在 venv 中如何或为什么会发生这种情况。

我的问题是我无法通过以太网连接连接到互联网。当我运行时wget http://google.com，我收到错误...failed: Name or service not known.Chrome 和 Firefox 无法加载任何引用连接问题的站点。

当我插入其他计算机时，以太网工作正常。是这台特定的机器无法正常工作。

这显然是一个 DNS 查找问题。

我在另一台机器上找到了 google.com 的 IP 地址。

ping -c3 172.217.11.142 

适用于 40 毫秒左右的 ping。

当我跑步时nslookup google.com，我得到;; connection timed ou; no servers could be reached

我在这里和这里尝试了使用 DHCP 和静态的解决方案，但没有任何好处。

我首先尝试使用 DHCP，然后是静态的

我昨晚从 16.04 升级到 17.10。甚至在重新启动之前，以太网就停止了工作。当我转到网络管理器并单击“自动以太网”时，我看到一个像这样的图像弹出：

它立即断开连接，类似于此图像

我已经挖掘了许多相关的帖子，但没有一个解决方案对我有用。

sudo nano /etc/NetworkManager/NetworkManager.conf

编辑为

[ifupdown] 托管=真

sudo service network-manager restart  #issue not resolved

显示我的托管/非托管连接

nmcli d

DEVICE TYPE STATE CONNECTION

sudo nano /etc/network/interfaces

编辑为

auto lo
iface lo inet loopback

重启网络管理器，还是不行

ifconfig

lsb_release -a确认我正在运行 17.10

我最近安装并安装了第二个硬盘驱动器。第二个硬盘使用 VMPlayer 来运行 Windows。我能够运行 VMPlayer，但前提是我使用gksudo vmplayer.

这显然是一个权限问题，阻止我从菜单图标运行它。我尝试/media/ssd通过切换root用户并应用chown来修改文件夹权限。出现错误Operation not allowed。

我也尝试过使用gksudo nautilus，它（毫不奇怪）给了我同样的错误信息。

我不相信它是相关的，但我在启动 nautilus 时收到了这些错误消息。

如果甚至不允许 root 更改目录权限，我该如何更改它？

编辑

我尝试按照外部硬盘驱动器不允许权限的建议进行操作。当我跑线时

sudo chattr +i immutable

我得到错误

chattr: Inappropriate ioctl for device while reading flags on immutable

这意味着什么？

这不是 NTFS/FAT32 问题的重复。我的分区类型是 vfat。

我正在尝试安装熊猫。当我这样做时，它会自动安装到 v 2.7 的 python 安装中。

如何强制 pandas 安装到 python 3.5 安装？
