无法在我的 ubuntu 机器 16.04 中安装 python3-tk

  • 772

我正在尝试像这样在 pycharm 中使用 tkinter 制作第一个桌面应用程序。

from tkinter import *

root = Tk()
mLabel = Label(root, text="This is Header")
mLabel.pack
mLabel.mainloop()

但我有一个例外说

ImportError: No module named '_tkinter', please install the python3-tk package

我试着像这样安装python3-tk

sudo apt-get install python3-tk

但后来我得到了一个关于install-info

ronem:::ronem:~$ sudo apt-get install python3-tk

    打开终端并输入：

    cat /etc/environment

    检查 in 中是否有一行/etc/environment包含CLASSPATH不属于 in的字符串/etc/environment。您应该注释/etc/environment除第一行（其设置以PATH开头）以外的所有内容，方法是在每行之前用一个字符PATH=注释掉。使用以下命令在 nano 文本编辑器中#打开文件进行编辑：/etc/environment

    sudo nano /etc/environment

    Nano 编辑器键盘快捷键
    使用键盘组合Ctrl+ O，然后按下Enter将文件保存到当前位置。
    使用键盘组合Ctrl+X退出 nano。
