安卓的回购工具在python2上失败了

Question

我的Dockerfile文件有python3，我得到：

RUN repo init -u https://android.googlesource.com/platform/manifest
 ---> Running in f3adc38c2aac
/usr/bin/env: 'python': No such file or directory

如果我安装了python，我会得到这样的错误：

Step 6/7 : RUN repo init -u https://android.googlesource.com/platform/manifest
 ---> Running in 9c03e1b95c0f
repo: warning: Python 2 is no longer supported; Please upgrade to Python 3.6+.

Repo的下载方式如下：

RUN mkdir -p /android_tools \
&& curl https://storage.googleapis.com/git-repo-downloads/repo > /android_tools/repo \
&& chmod a+x /android_tools/repo

Answer 1

https://storage.googleapis.com/git-repo-downloads/repo至少需要Python3.6。

要将python3与刚刚下载的repo一起使用，您需要修复shebang行：

sed -i '1s/python/python3/' /android_tools/repo
