求助，通过 Homebrew 无法编译 mpv 0.21.0

[steveshi]

mpv 出 0.21.0 版本的时候用 brew upgrade 更新就一直无法通过，索性拆卸重装，但一直出错…… Python 和 docutils 之类的也都重装过，出错的原因都是同一个。

系统版本

macOS 10.12.1

Homebrew 1.0.8

Python 3.5.2

错误显示

[helloSwift]

brew install mpv --with-bundle
brew linkapps mpv

[JackBlack2006]

lua 不是默认装的么，还加个命令干嘛

[steveshi]

@helloSwift 这样安装也是同样出错

[steveshi]

@JackBlack2006 之前命令是直接网上教程里的，不加 lua 也是同样错误

[JackBlack2006]

@steveshi 教程过时太快，你打 brew info mpv 一看就明白了

[Shared]

> ImportError: No module named docutils.core

需要安装 python-docutils 这个库

[steveshi]

@Shared 装了，还是提示这个，无论是用 brew 装还是 pip 装都还是这个错误。

[hackpro]

pip install docutils

[steveshi]

@hackpro Requirement already satisfied (use --upgrade to upgrade): docutils in /usr/local/Cellar/pyenv/1.0.2_1/versions/3.5.2/lib/python3.5/site-packages/docutils-0.12-py3.5.egg

[Shared]

pip 还是 pip3 安装的？ Python 2 和 3 都安装下试试

[steveshi]

@Shared 用 pip3 装的， python2 我直接是系统默认环境下的，没额外装，用 pyenv 指定了全局用 python3

[Shared]

@steveshi 你看这一句

> /usr/local/opt/docutils/bin/rst2man.py

不是 /usr/loca/Cellar 里的，应该还是 PATH 问题

[oxoxoxox]

brew link --overwrite docutils
你之前执行 brew upgrade -a 的时候里面其实有提示的，你肯定没注意看

[steveshi]

@Shared 我是怀疑 path 有问题，确实是识别不出 docutils ，但是这个路径上的文件都是存在的，我也晕了。

[steveshi]

@oxoxoxox 确实是 link 一下就好了……非常感谢
