我正在尝试使用 pycharm 中的 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
我尝试像这样安装 python3-tk
sudo apt-get install python3-tk
但后来我得到了一个错误install-info
ronem:::ronem:~$ sudo apt-get install python3-tk

打开终端并输入：
cat /etc/environment
检查 中是否有一行包含不属于 的/etc/environment字符串。您应该注释掉 中的所有内容，除了第一行（ 的设置以 开头），方法是在每行前面添加一个字符。使用以下命令在 nano 文本编辑器中打开文件进行编辑：CLASSPATH/etc/environment/etc/environmentPATHPATH=#/etc/environment
sudo nano /etc/environment
Nano 编辑器键盘快捷键
使用键盘组合键Ctrl+O然后按 将Enter文件保存到当前位置。
使用键盘组合键Ctrl+X退出 nano。
