The information isn't sufficient to reproduce the problem yet. Please include how exactly you create the package (with all the arguments you used as well as potential other edits of the manifest file). Also please post the content of your environment variables (the output of set).

You could also edit the source file where the exception is happening and try to add some debug output in that case to see what the variable line contains in that case.

My guess here would be that UTF-8 does not contain the Chinese character set. I'm not sure where the UTF-8 requirement is held.

calvertdw commented on June 20, 2024 1

The python decode method will require the correct encoding to be passed in, as it defaults to utf-8.

File "c:\python37\lib\site-packages\colcon_core\shell_init_.py", line 273, in get_environment_variables
parts = line.decode().split('=', 1)

It would be easy to patch the code to ignore environment variable which do contain characters which can't be decoded. Though I noticed that e.g. PATH contained chinese characters in your case and just skipping PATH wouldn't work. So it would be good to figure out how to make it work...

Can you please try the following command and post the output - it is trying to decode one of the problematic lines using your default encoding:

python -c "line=b'adb=D:\workInNingbo\appSource\\xb8\xbd\xbc\xfe\xcb\xc4\xa3\xba\xc1\xe9\xd4\xc6\xc2\xf3\xbf\xcb\xb7\xe7\xd5\xf3\xc1\xd0\xb5\xf7\xca\xd4\xc8\xed\xbc\xfe\adb\xbb\xb7\xbe\xb3\xb4\xee\xbd\xa8\xb9\xa4\xbe\xdf\xb0\xfc\platform-tools';line = line.decode('cp963'); print(line)"

HI,I made it.
The reason why it can't decode the string is that There are three lost "\" in the string

appSource\xb8 should be appSource\\\xb8

xfe\adb should be xfe\\adb

And It can work. I don't konw how it transforms between UTF-8 and cp936.
But fact is that something lost.

Here are command and result:
D:\dev\packages\helloworld>python -c "line=b'adb=D:\workInNingbo\appSource\\\xb8\xbd\xbc\xfe\xcb\xc4\xa3\xba\xc1\xe9\xd4\xc6\xc2\xf3\xbf\xcb\xb7\xe7\xd5\xf3\xc1\xd0\xb5\xf7\xca\xd4\xc8\xed\xbc\xfe\\adb\xbb\xb7\xbe\xb3\xb4\xee\xbd\xa8\xb9\xa4\xbe\xdf\xb0\xfc\platform-tools';line = line.decode('cp936'); print(line)"

I think the Result tow is what you want.

No, result 2 is not valid since you can't use non-ASCII characters in bytes.

Anyway I think using locale.getpreferredencoding() for decoding the lines (rather than using the default utf-8) seems to solve the problem for you. I created #95 which should fix the problem.

It would be great if you could try the proposed patch locally and confirm if it works afterwards (using the environment for which it fails currently). To install the modified version of colcon-core you can run:

pip install -U git+https://github.com/colcon/colcon-core.git@use_encoding_for_env

Please post any kind of output as text - images are not searchable.

Please also provide exact steps to reproduce the problem. In this case the content of your workspace as well as the locate you have set in your environment.

Thanks for your answer.
First I created a ROS2 package by using ros2 pkg create then I try to build it but failed.
I just Installed Binary packages in C:\dev\ros2 and didn't change anything about the loacte.
All location is same as the https://github.com/ros2/ros2/wiki/Windows-Install-Binary.
And my package location is C:\dev\ros2\mySource
Here is my error output. I'm sorry for that don't know how to correctly ask question.

And thank you for your patience.

I will try to debug to see if I can find out the reason.
PS: I tried to build a same package in my workmate computer and it worked.now I am so upset.

dzxsll commented on June 20, 2024

I find the problem in the Python37\Lib\site-packages\colcon_core\shell_init_.py and in the function get_environment_variables .

the code is here:

async def get_environment_variables(cmd, *, cwd=None, shell=True):
"""
Get the environment variables from the output of the command.
:param args: the sequence of program arguments
:param cwd: the working directory for the subprocess
:param shell: whether to use the shell as the program to execute
:rtype: dict
"""
output = await check_output(cmd, cwd=cwd, shell=shell)
env = {}
for line in output.splitlines():
print(line.rstrip())
line = line.rstrip()
if not line:
continue
parts = line.decode().split('=', 1)
if len(parts) != 2:
# skip lines which don't contain an equal sign
continue
env[parts[0]] = parts[1]
assert len(env) > 0, "The environment shouldn't be empty"
return env

I print out the variable "line" and result is that " b'adb=D:\workInNingbo\appSource\\xb8\xbd\xbc\xfe\xcb\xc4\xa3\xba\xc1\xe9\xd4\xc6\xc2\xf3\xbf\xcb\xb7\xe7\xd5\xf3\xc1\xd0\xb5\xf7\xca\xd4\xc8\xed\xbc\xfe\adb\xbb\xb7\xbe\xb3\xb4\xee\xbd\xa8\xb9\xa4\xbe\xdf\xb0\xfc\platform-tools' "

So what does that mean? what I can do ?

dirk-thomas commented on June 20, 2024

Can you please share information about your locale settings (by posting the output of the following commands):

python -c "import locale; print(locale.getlocale())"
python -c "import locale; print(locale.getdefaultlocale())"
python -c "import locale; print(locale.getpreferredencoding())"

from colcon-core.

dzxsll commented on June 20, 2024

Thank you for both answer. My win10 is the Chinese version but all location are named without any Chinese character. Should I change the os character set?

the output :
d:\dev\packages\1.helloworld>python -c "import locale; print(locale.getlocale())"
(None, None)

d:\dev\packages\1.helloworld>python -c "import locale; print(locale.getdefaultlocale())"
('zh_CN', 'cp936')

d:\dev\packages\1.helloworld>python -c "import locale; print(locale.getpreferredencoding())"
cp936

Let me try to change the character set and see what will happen.

from colcon-core.

dzxsll commented on June 20, 2024

oh, I get it. I see where have the Chinese characters.
when the colcon build a package, every environment variable will be sent to check.
However anyone chinese character can cause the question.
Now I deleted the variable and it can work!!!
I so appreciate your answer and patience.

dzxsll commented on June 20, 2024

The command doesn't work , I am sorry.
the cmd said LookupError:unkonwn encoding: cp963.
But I can show you the string which contains chinese characters.

dirk-thomas commented on June 20, 2024

That is weird that is can't even decode the string with the default locale of your system. If you can figure out what locale is required to decode the string correctly on your system I would be happy to work on a patch.

from colcon-core.

dirk-thomas commented on June 20, 2024

And if you run the same command with utf-8 (or no argument) instead of cp936? Does it raise a UnicodeDecodeError again?

I think the Result tow is what you want.
