Command "python setup.py egg_info" failed with error code

解决pip install MySQL-python 报Command "python setup.py egg_info" failed with error code 问题解决方法

此方法 可能对你不可行，我也是尝试了网上N种方法才解决好的，至于是哪种方法解决的我也不清楚

1、执行xcode-select --install
会弹出一个窗口，点击安装等待安装完成

(py2env) DsHdeMacBook-Pro:bin dsh$ xcode-select --install
xcode-select: note: install requested for command line developer tools

2、执行pip install MySQL-python

3、使用brew 安装mysql

4、执行brew install mysql

Error: Cannot install mysql because conflicting formulae are installed.
  mysql-connector-c: because both install MySQL client libraries

Please `brew unlink mysql-connector-c` before continuing.

Unlinking removes a formula's symlinks from /usr/local. You can
link the formula again after the install finishes. You can --force this
install, but the build may fail or cause obscure side-effects in the
resulting software.

按照要求执行brew unlink mysql-connector-c
5、再次执行brew install mysql

==> Downloading https://homebrew.bintray.com/bottles/mysql-5.7.19.sierra.bottle.
Already downloaded: /Users/dsh/Library/Caches/Homebrew/mysql-5.7.19.sierra.bottle.tar.gz
==> Pouring mysql-5.7.19.sierra.bottle.tar.gz
==> Caveats
We've installed your MySQL database without a root password. To secure it run:
    mysql_secure_installation

MySQL is configured to only allow connections from localhost by default

To connect run:
    mysql -uroot

To have launchd start mysql now and restart at login:
  brew services start mysql
Or, if you don't want/need a background service you can just run:
  mysql.server start
==> Summary
  /usr/local/Cellar/mysql/5.7.19: 322 files, 233MB

6、重新执行 pip install MySQL-python

7、终于执行成功，

我使用的是mac 系统， ubuntu系统应该更这个步骤差不多，如果有问题可以留言讨论。或者你有更好的方法，或者更好的解释这个问题的方式，可以告诉我，谢谢。
