我在我的机器上安装了node.js(linux mint 15),当我运行时node example.js,它说:

The program 'node' can be found in the following packages:
 * node
 * nodejs-legacy
Try: sudo apt-get install <selected package>

那么node和nodejs之间有什么区别呢？我之前安装了node.js和node,但是当我运行时node example.js,Web服务器根本没有启动.所以我删除了节点并保留了node.js.

我在我的Linux Mint机器上安装了Postgresql 9.3和9.4.如何重新启动postgresql 9.4？一起重启两个版本的方法也没问题.

C++在Qt创建器中调试代码时,我收到以下错误

ptrace: Operation not permitted.

Could not attach to the process. Make sure no other debugger traces this process.
Check the settings of
/proc/sys/kernel/yama/ptrace_scope
For more details, see /etc/sysctl.d/10-ptrace.conf

这里找到了一个临时解决方案:尝试在QtProject中调试时收到错误

• 临时解决方案(无法重启):

  echo 0 | sudo tee /proc/sys/kernel/yama/ptrace_scope

但是每次启动PC使用Qt时,很难在终端中运行相同的代码.

What is the permanent solution for this?

我刚刚按照位于https://www.digitalocean.com/community/articles/how-to-install-linux-apache-mysql-php-lamp-stack-on-ubuntu的教程,同时修复了我来的其他多个错误一路走来,我遇到了最后一个错误.当我登录到phpMyAdmin时,底部有一个巨大的红色错误,说"缺少mcrypt扩展名.请检查你的PHP配置.".我通过putty安装了Ubuntu 13.10教程中列出的所有内容.

在Linux Mint 17.1 x86_64上,内核3.13.0-48-generic和OpenSSL版本1.0.1f-1ubuntu2.11; 每当我尝试执行任何docker命令(如docker login或docker run hello-world)时,我都会收到以下错误:

FATA[0000] Get http:///var/run/docker.sock/v1.18/info: dial unix /var/run/docker.sock: no such file or directory. Are you trying to connect to a TLS-enabled daemon without TLS? 

我做了一组名为docker使用sudo usermod -aG docker username,我试图同时运行的根和正常的命令,添加$(boot2docker shellinit 2> /dev/null)到~/.profile的指示在这里,重新开始我的电脑并重新安装OpenSSL的.

知道我错过了什么吗？这可能是硬件问题吗？

我使用Linux Mint的肉桂14.我已设置$JAVA_HOME和$PATH环境变量~/.profile如下:

export JAVA_HOME=/home/aqeel/development/jdk/jdk1.6.0_35
export PATH=/home/aqeel/development/jdk/jdk1.6.0_35/bin:$PATH

然后我source ~/.profile做了适当的改变.

当我执行java -version命令来检查活动的java版本时,它会显示默认的(已安装的open-jdk)java版本.如何用我下载的那个覆盖默认的open-jdk？

更新:

which java/usr/bin/java

$JAVA_HOME/bin/java -version 说'权限被拒绝'

sudo $JAVA_HOME/bin/java -version (请求密码,然后说)找不到命令

但是cd $JAVA_HOME/bin,并ls表明它是正确的目录.

我刚刚在我的Linux Mint 18.1 Cinnamon机器上更新到R(3.4.1"单烛"),我试图安装一个包.R返回以下内容:

> install.packages('ggplot2')
Installing package into ‘/usr/local/lib/R/site-library’
(as ‘lib’ is unspecified)
Warning in install.packages("ggplot2") :
  'lib = "/usr/local/lib/R/site-library"' is not writable
Would you like to use a personal library instead?  (y/n) y
Would you like to create a personal library
NA
to install packages into?  (y/n) y
Error in install.packages("ggplot2") : unable to create ‘NA’

我之前遇到过'lib not writable'输出,但通常它提供了类似这样的解决方案:

Would you like to create a personal library
~/R/x86_64-pc-linux-gnu-library/3.4
to install packages into?  (y/n) y 

个人图书馆建议NA的任何想法？有没有办法手动覆盖这个？

我想激活elasticsearch的日志.

当我运行elasticsearch二进制文件时,我意识到我的日志记录存在问题:配置无法加载!

这是输出:

按照此页面上的说明在 python2 https://linuxhint.com/installing_pip_linux_mint/上安装 pip

最后一步失败了 $ sudo python2 get-pip.py

出现这个错误，

Traceback (most recent call last):
  File "get-pip.py", line 24226, in <module>
    main()
  File "get-pip.py", line 199, in main

    sys.stderr.write(f"ERROR: {exc}")
                                   ^
SyntaxError: invalid syntax

我试图到处寻找解决方案，但找不到。我做错了什么？

我已经在网上坐了几个小时,已经尝试在Linux上的Clion上设置Google测试但是却找不到任何东西.

有人可以指导我设置吗？
