Carol.Kar's questions

我在 VirtualBox 上运行Ubuntu 18.04.5 LTS。我正在跑步Python 3.6.9。

尝试创建虚拟环境时，sudo python3 -m venv env我得到：

admin@admin-VirtualBox:~/Desktop/project$ sudo python3 -m venv .venv
The virtual environment was not created successfully because ensurepip is not
available.  On Debian/Ubuntu systems, you need to install the python3-venv
package using the following command.

    apt-get install python3-venv

You may need to use sudo with that command.  After installing the python3-venv
package, recreate your virtual environment.

Failing command: ['/home/admin/Desktop/project/.venv/bin/python3', '-Im', 'ensurepip', '--upgrade', '--default-pip']

admin@admin-VirtualBox:~/Desktop/project$ python3 --version
Python 3.6.9
admin@admin-VirtualBox:~/Desktop/project$ sudo apt-get install python3.6-venv

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 python3.6-venv : Depends: python3.6 (= 3.6.5-3) but 3.6.9-1~18.04ubuntu1.1 is to be installed
E: Unable to correct problems, you have held broken packages.
admin@admin-VirtualBox:~/Desktop/project$ 

我研究并发现python3已经venv预装了。我相信有一些破碎的依赖关系。

我试过了：

admin@admin-VirtualBox:~/Desktop/project$ sudo apt-cache policy python3.6-venv python3.6 python3
python3.6-venv:

任何建议如何解决这个问题？问题是什么？

感谢您的回复！

我正在使用Ubuntu 18.04.5 LTS.

我创建了以下脚本来将文件夹中的文件拆分为不同的子文件夹：

#!/bin/bash

dir_size=850
dir_name="images"
n=$((`find . -maxdepth 1 -type f | wc -l`/$dir_size+1))
for i in `seq 1 $n`;
do
    mkdir -p "$dir_name$i";
    find . -maxdepth 1 -type f | head -n $dir_size | xargs -i mv "{}" "$dir_name$i"
done

但是，我想zip在创建后每个子文件夹，这样我只能在我的最终目录中获得压缩的子文件夹。

任何建议如何做到这一点？

感谢您的回复！

我在我的 VPSUbuntu 20.04.1 LTS和本地运行Ubuntu 18.04.3 LTS，我想创建一个 ssh 隧道来连接到我的数据库以SELECT在我的应用程序中运行以进行报告laravel 6。

我的生产数据库在我的服务器上具有以下凭据：

DB_HOST_PROD=127.0.0.1
DB_PORT_PROD=3306
DB_DATABASE_PROD=test_db
DB_USERNAME_PROD=root
DB_PASSWORD_PROD=prod_pwd

运行时我ssh-command得到：

我在本地运行我的开发数据库：

DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=test_db
DB_USERNAME=root
DB_PASSWORD=local_pwd

为什么我会收到消息bind: Address already in use？

有什么建议我做错了吗？

我正在使用Ubuntu 18.04.3 LTS并且已经安装dbeaver：

sudo add-apt-repository ppa:serge-rider/dbeaver-ce
sudo apt-get install dbeaver-ce

我有一个setupDevEnvironment脚本，我想从控制台启动 dbeaver，但还没有找到方法。

任何建议如何做到这一点？

感谢您的回复！

我正在使用Ubuntu 18.04.3 LTS.

目前要启动我的开发环境，我必须在终端中运行以下每个命令：

sudo systemctl stop apache2

sudo /opt/lampp/manager-linux-x64.run

sudo /opt/PhpStorm-193.6015.48/bin/phpstorm.sh 

sudo chmod -R 777 Desktop/Code/testProject

我想双击我桌面上的脚本并自动生成需要在后台运行的两个终端lampp和phpstorm

但是，当当前执行脚本时，它只启动lampp-server。

有什么建议我做错了吗？

感谢您的回复！

我正在使用Ubuntu 18.04.3 LTS和。xamppphp 7.4

我正在尝试更改> php路径变量。

我试过了：

admin@admin:/opt/lampp/bin$ sudo ln -s /opt/lampp/bin/php /usr/bin/php
admin@admin:/opt/lampp/bin$ which php
/usr/bin/php

如您所见，我的路径变量似乎在/usr/bin/php.

1. 如何检查当前路径变量php？
2. 如何将xampp'sphp 可执行文件设置为PATH变量？

感谢您的回复！
