SyntaxError：AOSP 代码中 repo init 的语法无效

Question

I have tried to repo init the source code Ubuntu build machine and it is successfully able to clone the code.

repo init -u git@github.com:xxx/xx_manifest.git -b xxx

Now I am trying repo init the source code in VM Ubuntu machine.

In between getting the error like below:

Traceback (most recent call last):
 File "/xxx/.repo/repo/main.py", line 56, in <module>
from subcmds.version import Version
 File "/xxx/.repo/repo/subcmds/__init__.py", line 38, in <module>
['%s' % name])
 File "/xxx/.repo/repo/subcmds/upload.py", line 27, in <module>
from hooks import RepoHook
File "/xxx/.repo/repo/hooks.py", line 472
file=sys.stderr)
    ^
 SyntaxError: invalid syntax

python version is same in build machine and vm machine 2.7.17.

Answer 1

try these commands

curl https://storage.googleapis.com/git-repo-downloads/repo-1 > ~/bin/repo
chmod a+x ~/bin/repo
python3 ~/bin/repo init -u git@....

Answer 2

I just had the same issue and this resolved it for me:

• Download last version of repo: curl https://storage.googleapis.com/git-repo-downloads/repo-1 > repo
• Change right to make it executable: chmod a+x repo
• Run your repo init with python3 and the "repo" you just download: python3 repo init -u git@github.com:xxx/xx_manifest.git -b xxx

I have experienced the same issue on Ubuntu 18.04 during the installation of the OpenSTLinux Yocto layer with the following command:

repo init -u https://github.com/STMicroelectronics/oe-manifest.git -b refs/tags/openstlinux-5.4-dunfell-mp1-20-11-12

Returns:

This issue goes away with using Python3 instead of Python (2.7). You can do this:

sudo rm /usr/bin/python
sudo ln -s /usr/bin/python3 /usr/bin/python

Answer 4

Try below command to make it will work 100%, tried & suggested

mkdir -p ~/.bin
PATH="${HOME}/.bin:${PATH}"
curl https://storage.googleapis.com/git-repo-downloads/repo > ~/.bin/repo
chmod a+rx ~/.bin/repo

Answer 5

One solution is to modify the first line of /usr/bin/repo and change it from

#!/usr/bin/python

to

#!/usr/bin/python3

This asks the system to use Python3 instead of the default Python.

Answer 6

If the system you are running on doesn't have python3, like in my case, and you don't have the option to install python3, or installing it breaks other parts, the option is the degrade repo to a version that uses python2.7:

- git clone https://gerrit.googlesource.com/git-repo
- cd git-repo
- git reset --hard v1.13.11
- mkdir -p ~/.bin
- PATH="${HOME}/.bin:${PATH}"
- cp repo ~/.bin/repo
- chmod a+rx ~/.bin/repo

This will use v1.13.11 of repo, which works with python2.7

Answer 7

As seen in a similar error in arvestad/alv issue 1 , that would be consistent with running the process with Python 2.7 instead of Python3

Double-check you Python version between:

• your Ubuntu build machine (where the repo init works)
• your VM Ubuntu machine (where the repo init fails)

Same error here , with the error suggesting you are executing python2 with a PYTHONPATH that's only appropriate for python3 .

Answer 8

I don't know exactly how this works, but i just had the same issue and this resolved it for me it seems.

https://source.android.com/setup/develop#installing-repo Dont use the legacy one, use the first one to resolve it.

Edit: It seems you also need to have python 3.6 installed on you system to have this work. You can still have update-alternatives point to python 2.7, you simply need 3.6 or newer installed.

Answer 9

Just install python3 and the latest repo.

I encountered the problem too, but on Mac OS. The log is exactly the same as yours. Definitely python2 caused this problem. repo is try to run python3 files in python2 environment.

I found the this from repo docs https://gerrit.googlesource.com/git-repo/+/refs/heads/master/docs/python-support.md

So I update my repo (which located in depot_tools). Since I already have python3 installed, everything is ok now.

Hope my experience may help you.
