From around Mar 16, after pulling the latest m-c, I can no longer build Firefox desktop on my Mac. I am getting the following message from |./mach build|:

I've tried the following and they don't appear to fix the problem, but only at (4):

1. Comment out the line pointed out by the error in modules/libmar/tests/moz.build; the same error will show up just with different moz.build name.
2. Upgrade all my local Python packages from pip.
3. |git clean -dfx .| and also remove my objdir.
4. Checkout old versions -- works, and |git bisect| points the first bad commit to bug 1203266 (at https://hg.mozilla.org/mozilla-central/rev/fd993badf8b7 ). The strange thing is the date of the commit (Mar 8) is not consistent to my work dir history.

Noted that I might have |brew upgrade| a dependent package between the last successful build and the first failure build. However |./mach bootstrap| checks out:

```
Looks like you have Homebrew installed. We will install all required packages via Homebrew.

Your version of Mercurial (3.7.2) is sufficiently modern.
Your version of Python (2.7.11) is new enough.
```

Per https://dxr.mozilla.org/mozilla-central/source/python/mozboot/mozboot/osx.py#307-324 I am listing some of the package versions (ask me for more):

$ gtar --version
tar (GNU tar) 1.28
$ git --version
git version 2.7.4
$ autoconf213 --version
Autoconf version 2.13
$ watchman --version
4.4.0
$ yasm --version
yasm 1.3.0

Unfortunately I don't know where the TypeError came from (there is no line # printed in the error). |reader.py| doesn't seem to have any extra, offending `folder=` call site.

I wonder if I am the only one blocked by this error? Chris, is this something you could help? Thanks!

BTW, I never mention I am on OS X 10.10 and is planning to upgrade to 10.11 soon. Should I keep the environment so we could keep debugging?

With try-and-error, I found an workaround of this bug:

I can now confirm the problem come from manifestparser v1.1 installed in my Python environment! The bug is fixed by removing that from it: |pip uninstall manifestparser|.

The `import` here needs to point the copy of manifestparser in the tree, instead of the one in the environment.

https://dxr.mozilla.org/mozilla-central/rev/b3006e4e09af81825badbad69fa3e8c546c7507c/python/mozbuild/mozbuild/testing.py#17

I can see plain `import manifestparser` elsewhere in the tree as well. I don't understand Python well enough, however, to know to reference the manifestparser in the tree (and how they ended up import the one in the tree when there isn't one installed).

BTW, manifestparser must have been installed globally when I installed something need it like mozregression I guess? Below is my `pip list` after uninstalling manifestparser:

Summary: "TypeError: __init__() got an unexpected keyword argument 'finder'" when running recent m-c build → Prefer referencing manifestparser in the tree (instead of in the installed package)
Interesting. The build system should be running inside m-c virtualenv right?

https://developer.mozilla.org/en-US/docs/Python/Virtualenv#The_Mozilla-Central_Virtualenv

I checked |obj-x86_64-apple-darwin14.5.0/_virtualenv/lib/python2.7/site-packages/manifestparser.pth| and it does output the correct path when the build errored:  ../../../../../testing/mozbase/manifestparser
Add a |print sys.path| in testing.py gives me this, which puts system path before local path:

I am a bit confused where the paths are being added, since there is a comment in mach_bootstrap.py on bug 794506, but that bug was marked as fixed.
I'm not sure exactly what went wrong here, but from comment 8, the problem appears to be paths in /usr/local/Cellar coming before those in the tree. :gps may have more background on how to avoid this.

Yes this is still an issue. Update to the latest m-c and try

$ pip install manifestparser==1.1
$ mach build

Still produce the same error in comment 0.
