aman@aman-HP-Pavilion-Notebook:~$ pip

The program 'pip' is currently not installed. You can install it by typing:
sudo apt-get install python-pip

aman@aman-HP-Pavilion-Notebook:~$ sudo pip

sudo: pip: command not found

aman@aman-HP-Pavilion-Notebook:~$

尝试使用以下命令：

import com.vaadin.contextmenu.GridContextMenu;
import com.vaadin.icons.VaadinIcons;
import com.vaadin.ui.Grid;
import com.vaadin.ui.Notification;
import com.vaadin.ui.UI;
import com.vaadin.ui.VerticalLayout;

public class MyUi extends UI {
    @Override
    protected void init(VaadinRequest request) {
        // basic grid setup
        Grid<Person> grid = new Grid<>(Person.class);
        grid.getColumns().forEach(column -> column.setHidable(true).setSortable(true));
        grid.setItems(
                new Person("Darth", "Vader"),
                new Person("Luke", "Skywalkaer"),
                new Person("Java", "De-Hut")
        );

        // grid context menu setup
        Random random = new Random();
        GridContextMenu<Person> contextMenu = new GridContextMenu<>(grid);
        // handle header right-click
        contextMenu.addGridHeaderContextMenuListener(event -> {
            contextMenu.removeItems();
            contextMenu.addItem("Hide", VaadinIcons.EYE_SLASH, selectedMenuItem -> {
                event.getColumn().setHidden(true);
            });
            contextMenu.addItem("Sort", VaadinIcons.LIST_OL, selectedMenuItem -> {
                grid.sort(event.getColumn().getId(), SortDirection.values()[random.nextInt(2)]);
            });
        });
        // handle item right-click
        contextMenu.addGridBodyContextMenuListener(event -> {
            contextMenu.removeItems();
            if (event.getItem() != null) {
                grid.select((Person) event.getItem());
                contextMenu.addItem("Info", VaadinIcons.INFO, selectedMenuItem -> {
                    Notification.show("Right-clicked item " + event.getItem());
                });
            }
        });

        // set UI content
        VerticalLayout content = new VerticalLayout();
        content.setSizeFull();
        content.addComponents(grid);
        setContent(content);
    }

    // basic bean
    public static class Person {
        private String firstName;
        private String lastName;

        public Person(String firstName, String lastName) {
            this.firstName = firstName;
            this.lastName = lastName;
        }

        public String getFirstName() {
            return firstName;
        }

        public void setFirstName(String firstName) {
            this.firstName = firstName;
        }

        public String getLastName() {
            return lastName;
        }

        public void setLastName(String lastName) {
            this.lastName = lastName;
        }

        @Override
        public String toString() {
            return "Person{" +
                    "firstName='" + firstName + '\'' +
                    ", lastName='" + lastName + '\'' +
                    '}';
        }
    }
}

验证

sudo apt-get purge --auto-remove python-pip

sudo apt-get update

sudo apt-get -y install python-pip

curl "https://bootstrap.pypa.io/get-pip.py" -o "get-pip.py"

python get-pip.py

问题可能是Ubuntu 14.04 Universe存储库中的软件包。

如果不起作用，请从此处下载.deb：

https://packages.ubuntu.com/trusty/all/python-pip/download

并右键单击.deb并安装

问题可能是你的PC在不同的位置安装了两个版本的python 2，其中一个python的pip以某种方式被删除了。因此，当您尝试为副本安装pip时，系统会说已经在另一个位置安装了一个pip，并且/ usr / local / bin文件夹也缺少用于安装pip的pip文件。

我刚刚解决了这个问题所以我会尝试以某种方式解释它，以便初学者也能正确理解它

将已安装的pip文件复制到丢失的位置，而不是通过命令安装它，因为命令将检测已安装的pip。

解决方案非常简单：

在Ubuntu的终端（命令提示符）中运行这些命令

哪个点子

＃获取已安装的pip文件的位置

cp位置由pip位置提供哪里复制pip文件

希望它有所帮助。

无法在ubuntu中安装pip？
