I keep getting this error when trying to install mediasoup. I’m using macOS btw.

Thanks,  
Philip

Please, specify at least which version of mediasoup you are installing. And also type `python --version` output, OSX version, etc.

macOS: 10.14.5  
mediasoup: 3.0.12  
node: 10.15.0  
python: 3.6.6 (I also have python2 with version 2.7.15)  
yarn: 1.16.0

It works for me with:

- macOS: 10.14.4
- mediasoup: 3.0.12
- node: 10.15.0
- python: 3.7.2
- yarn: 1.16.0

Please, try two different approaches:

### 1. Install mediasoup with Python 2

Assuming you have `python2` command:

```bash
$ PYTHON=python2 yarn add mediasoup

```

### 2. Upgrade Python 3 to 3.7.2

Or newer. AFAIS I’ve got it via Homebrew. And try again.

And since this looks a bug, please let’s continue in GitHub (I’ve reopened the corresponding issue):

</div>

I’ve tried the following and unfortunately all of them failed:

- PYTHON=python2 yarn add mediasoup (2.7.15)
- yarn add mediasoup (upgraded to 3.7.3)
- PYTHON=/usr/local/Cellar/python@2/2.7.16/bin/python yarn add mediasoup (tried using homebrew’s python)

I also tried disabling nvm and manually installing node 10.16.0 and it’s still failing for me.

I’m not sure if it matters but I also use pyenv.

</div>

Definitely no idea. Can you experiment without `yarn`? I mean, clone the mediasoup repo, enter into the `worker` directory and run:

- `make`
- `PYTHON=xxxxxx make`
- etc

Also, are you sure that when you have tested `yarn add mediasoup (upgraded to 3.7.3)` you have used python 3.7.3?

Okay I’ve tried what you’ve suggested and added some print statements in mac-tool.py

Does this help?

```auto
for line in err.splitlines():
    print("Line:", line, "\n")
    if not libtool_re.match(line) and not libtool_re5.match(line):
        print(line, file=sys.stderr)

Modifying mac\_tool.py works!

```auto
for line in err.splitlines():
      decoded_line = line.decode("utf-8") 
      if not libtool_re.match(decoded_line) and not libtool_re5.match(decoded_line):

I’ve added that path in mediasoup v3 branch and also made a change to prefer `python2` if available:

> <https://github.com/versatica/mediasoup/commit/3d09304a639984f7d01e73a567ac10da598b5ec7?ts=2>

Can you please try with v3 branch to see if it works? Note that it would now choose `python2` by default, so in order to test python 3 just do `PYTHON=python3 make` as you know 🙂

Let’s make this question as resolved and let’s continue in the gyp issue in chromium.
