此方法 可能對你不可行，我也是嘗試了網(wǎng)上N種方法才解決好的，至于是哪種方法解決的我也不清楚

1、執(zhí)行xcode-select --install
會彈出一個窗口，點(diǎn)擊安裝等待安裝完成

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

2、執(zhí)行pip install MySQL-python

3、使用brew 安裝mysql

4、執(zhí)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.

按照要求執(zhí)行brew unlink mysql-connector-c
5、再次執(zhí)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、重新執(zhí)行 pip install MySQL-python

7、終于執(zhí)行成功，??

我使用的是mac 系統(tǒng)， ubuntu系統(tǒng)應(yīng)該更這個步驟差不多，如果有問題可以留言討論?；蛘吣阌懈玫姆椒ǎ蛘吒玫慕忉屵@個問題的方式，可以告訴我，謝謝。
