  • 出了什么问题:评估根项目“ android”时发生问题。

    找不到安装的构建工具。 请安装Android构建工具版本19.1.0或更高版本。

我看到很多关于写入SD卡的帖子,但我相信我的问题是不同的。 在构建AVD的过程中,我无法创建SD卡。

我最初尝试使用Android SDK和AVD Manager来执行此操作,选择
姓名 :my_avd
目标 :Android 2.2 – API级别8
SD卡 :尺寸:1024 MiB
皮肤 :内置:默认(HVGA)
硬件 :属性:抽象LCD密度,值:160



[email protected]:~$ android create avd -n my_avd -t 1 -c 1024M
Android 2.2 is a basic Android platform.
Do you wish to create a custom hardware profile [no]no
Error: Failed to create the SD card.

试图遵循使用mksdcard的说明同样没有效果; 我认为我基本缺乏linux经验可能​​会让我在这里遇到问题。 当我尝试使用mksdcard时,它只是报告它找不到文件或目录。 mksdcard工具是否可以在linux中以这种方式使用?

[email protected]:~$ mksdcard 1024M ./sdcard.iso
bash: /home/alex/android-sdk-linux_x86/tools/mksdcard: No such file or directory
[email protected]:~$ sudo android create avd -n my_avd -t 1 -c 1024M

我已经将android工具目录添加到我的PATH变量中,但我觉得显然还有其他一些我不知道的东西。 也许某种访问权限?

我甚至尝试安装Eclipse和ADT插件并从那里运行管理器无济于事。 任何提示将非常感激。 高级警告,我有点像新手Linux用户,所以即使看起来像是一个明智的事情要检查,我仍然可能错过了它。

I see a lot of posts about writing to the SD card, but I believe my problem is different.I am unable to create the SD card during the process of building an AVD.I initially tried to use the Android SDK and AVD Manager to do this, selectingName : my_avdTarget : Android 2.2 – API Level 8SD Card : Size: 1024 MiBSkin : Built-In: Default (HVGA)Hardware : Property: Abstracted LCD Density, Value: 160This pops up a window with the message:”Result of creating AVD ‘my_avd’:Error: Failed to create the SD card.”I tried to repeat the process from the command line, receiving a similar error:Attempting to follow instructions for using mksdcard was equally unproductive;I think my basic lack of linux experience may be causing me a problem here.When I try to use mksdcard, it just reports that it cannot find the file or directory.Is the mksdcard tool available for use this way in linux?I’ve added the android tools directory to my PATH variable, but I feel like there is obviously something else I’m missing.Perhaps some kind of access rights?Attempting to run the android command with sudo did not seem to help either:I even tried installing Eclipse and the ADT plugin and running the manager from there to no avail.Any tips would be most appreciated.Advanced warning that I am somewhat of a novice Linux user, so even if it seems like a no-brainer obvious thing to check, I could still have missed it.


按照我在这里找到的说明,我一直在使用Docker来运行Quantum GIS: docker-qgis-desktop-运行QGIS桌面的简单docker容器


来自守护程序的错误响应:冲突。 容器235566ae17b8已使用名称“ qgis-desktop-2-4”。 您必须删除(或重命名)该容器才能重用该名称。

尽管在此站点上寻找了线索,但我不确定是什么意思。 在此之前,我没有做任何更改,并且已经使用以下命令成功启动了容器:

sudo docker run --rm --name="qgis-desktop-2-4"     -i -t     -v ${HOME}:/home/${USER}     -v /tmp/.X11-unix:/tmp/.X11-unix     -e DISPLAY=unix$DISPLAY     kartoza/qgis-desktop:latest


I’ve been using Docker on my to run Quantum GIS following instructions I found here: docker-qgis-desktop – A simple docker container that runs QGIS desktopEverything has been running fine until last week when I started to get this error message:Error response from daemon: Conflict.The name “qgis-desktop-2-4” is already in use by container 235566ae17b8.You have to delete (or rename) that container to be able to reuse that name.I’m not entirely sure what this means despite searching for clues on this site.I hadn’t changed anything prior to this happening and have been successfully launching the container with this command:How can I fix this?



  • 新鲜的Ubuntu 16.04
  • 用PHP 7
  • 安装MySQL 5.7

     sudo apt-get install mysql-common mysql-server 


mysql -u root -p



ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock'




ERROR 1698 (28000): Access denied for user 'root'@'localhost'.

可能的问题? “root”用户的密码错误!

解决方案: 使用本教程重置root密码



mysql "ERROR 1524 (HY000): Plugin 'unix_socket' is not loaded"


My local environment is:fresh Ubuntu 16.04with PHP 7with installed MySQL 5.7When I tried to login to MySQL (via CLI):I came across an cyclic issue with 3 steps.1) First was some socket issueSolution: restarting PC.Which led to another error:2) With access deniedPossible issue?Wrong password for “root” user!Solution: reset root password with this tutorial .With correct password and working socket, there comes last error.3) Incorrect auth pluginHere I stopped or somehow got to 1) again.
