我正在从头开始构建Arch Linux系统,目前系统中没有Python.我可以使用以下命令安装Python2.7:

pacman -S python2

但是当我尝试为python安装一些软件包时:

pacman -S python-numpy

Pacman只显示下载Python3.x的选项和Python3.x的numpy.没有其他选择.我如何确保在搜索Python内容时,它只根据我安装的Python版本进行搜索？我的系统中没有Python3,我根本不需要它.在我的Ubuntu系统中,我没有指定Python版本,但总是要处理它.我不知道如何在Arch Linux中处理这个问题.

提前致谢!

我在机器上的轨道上设置ruby时遇到了麻烦.我一直在关注"使用Rails进行敏捷Web开发"一书,直到现在一切都很顺利.

我遇到的问题是当我输入时

rails server

我收到以下错误:

如今设置网络接口指标的正确方法是什么？

我正在寻找命令行方式来做到这一点.我目前正在使用Arch Linux,但是首选的是不依赖于发行版的方法.

这是我失败的尝试:

$ sudo ifconfig wlan0 metric 1
SIOCSIFMETRIC: Operation not supported

我正在使用Arch Linux与Gnome.

我通过桌面项打开Android Studio.代码编辑器工作正常,设备管理器正常启动,应用程序像魅力一样运行,但当我尝试打开设备监视器时,我收到此错误:

必须提供Java运行时环境(JRE)或Java Development Kit(JDK)才能运行Monitor.搜索以下位置后找不到Java虚拟机:/ home/gram/Android/Sdk/tools/lib/monitor-x86_64/jre/bin/java java当前PATH当我从命令行运行android studion时,设备监视器工作.

这是.desktop内容

#!/usr/bin/env xdg-open

我的JRE和JDK变量正在/ etc/profile上添加.当我在命令行上运行Android Studio时,不会发生此错误.也许这是Gnome发射器的问题？

我在我的机器上运行 Docker Compose 时遇到这个问题。我换了机器，问题依然存在。

错误信息：

[40335] Error loading Python lib '/tmp/_MEIR5kRcn/libpython3.7m.so.1.0': dlopen: libcrypt.so.1: cannot open shared object file: No such file or directory

我的操作系统已完全更新。

我已经尝试过此处、此处和此处列出的解决方案。

这是 的输出ldd --version。

ldd (GNU libc) 2.35

Docker 本身正在按预期运行。然而 Docker-compose 却不是。尝试docker-compose up或docker-compose --version会导致错误。

嗨,有Stackoverflow黑客!

我有一个非常小的问题,或者我和C syslog()函数之间的误解.

代码编译得很好,我可以看到它正在做它的"虚拟工作"(ping 8.8.8.8),但是定义的日志不会附加.我对此完全感到困惑,并且不知道可能出现什么问题.已经SMAO(搜索我的屁股 - 尝试推广它),但只是无法让它正常工作.

代码在这里:

#include <sys/types.h>
#include <sys/stat.h>
#include <stdio.h>
#include <stdlib.h>
#include <fcntl.h>
#include <errno.h>
#include <unistd.h>
#include <syslog.h>
#include <string.h>

// Application settings # TODO: import these from a .ini file

#define WORKDIR   "/var/run/management"
#define LOGDIR    "/var/log/management"
#define LOGFILE   "/var/log/management.log"
#define SCRIPTDIR "/var/spool/management"
#define PIDFILE   "/var/run/management/daemon.pid"

int main(void) {
  printf("Management Daemon\nInitializing...");
  pid_t pid, sid;

  setlogmask(LOG_UPTO (LOG_NOTICE));
  openlog(LOGFILE, LOG_CONS | LOG_PID | LOG_NDELAY, LOG_LOCAL1);
  syslog(LOG_NOTICE, "Management Daemon started by User %d", getuid());
  closelog();

  printf("Done.\nForking...\n");

  pid …

Arch Linux 在安装新软件包之前更新软件包的命令是什么？

例如,我知道在Ubuntu中,我这样做:

$ sudo apt-get update
$ sudo apt-get <pkg-name>

Arch怎么样？

我遇到了几个版本,但他们似乎并不认同对方.我看不出那里的一致性.

例如1.(对我来说这看起来很乏味):

$ sudo pacman -Syy
$ sudo pacman -Su

例如.2:

$ sudo pacman -Sy

例如.3:

总是使用"-Sy"和"u"即"pacman -Syu"然后"pacman -S",而不是"pacman -Sy".

我只是困惑!

有任何想法吗？

我刚刚将我的arch linux系统更新到包含gcc 7.1.1的最新版本.试图建立这个:

#include <functional>

int main(int argc, char** argv) {
    return 1;
}

使用命令

clang++ main.cpp -std=c++1z

导致错误:

我是 docker 新手，我尝试创建一个自定义图像，我可以在其中简单地运行，pacman -Syu --noconfirm但出现以下错误：

error: failed to initialize alpm library
(could not find or read directory: /var/lib/pacman/)
The command '/bin/sh -c pacman -Syu --noconfirm' returned a non-zero code: 255

我的 dockerfile 是：

#This is a sample Image 
FROM archlinux

RUN pacman -Syu --noconfirm 
CMD [“echo”,”Image created”] 

在Archlinux上安装docker时，出现以下错误：

error: runc: signature from "Frederik Schwan <frederik.schwan@linux.com>" is unknown trust
:: File /var/cache/pacman/pkg/runc-1.0.3-1-x86_64.pkg.tar.zst is corrupted (invalid or corrupted package (PGP signature)).

有人可以帮我解决这个问题，因为它阻止我安装 docker 吗？
