python - 在Docker容器上运行Tkinter

Question

我是使用docker的新手，目前正在学习如何构建和运行docker镜像。我成功地构建了docker镜像，但是，运行该镜像时出现此错误:

Traceback (most recent call last):
  File "gui.py", line 1, in <module>
    import tkinter as tk
  File "/usr/local/lib/python3.7/tkinter/__init__.py", line 36, in <module>
    import _tkinter # If this fails your Python may not be configured for Tk
ImportError: Error loading shared library libtk8.6.so: No such file or directory (needed by /usr/local/lib/python3.7/lib-dynload/_tkinter.cpython-37m-x86_64-linux-gnu.so)

Dockerfile:

FROM python:alpine3.8 
COPY . /app
WORKDIR /app
RUN pip3 install -r requirements.txt 
ENTRYPOINT [ "python3" ] 
CMD [ "gui.py" ] 

Requirements.txt:

gspread
oauth2client
fpdf
networkx

我正在尝试在docker中运行Tkinter应用程序。我该如何解决？任何帮助将非常感激。谢谢!

好像package tk丢失了，希望可以解决您的问题。从Dockerfile安装tk的alpine软件包。修改您的dockerfile以如下所示安装它，

FROM python:alpine3.8 
COPY . /app
WORKDIR /app
RUN apk update && apk add tk
RUN pip3 install -r requirements.txt 
ENTRYPOINT [ "python3" ] 
CMD [ "gui.py" ] 

如果仍然有任何缺少的软件包，只需使用RUN apk add <package1> <package2>添加它们
