在 Mac OS X Sierra 上为 Django Python 安装 mysqlclient

Question

我已经安装了

• Python 2.7.13
• Django 1.11
• MySQL 5.7.17

我想在 Django 中使用 MySQL，但在安装 mysql 连接器后，我尝试在 $ pip install mysqlclient 上安装 mysqlclient for Python，但我遇到了这个问题：

Collecting mysqlclient
  Using cached mysqlclient-1.3.10.tar.gz
    Complete output from command python setup.py egg_info:
    Traceback (most recent call last):
      File "<string>", line 1, in <module>
      File "/private/var/folders/y_/c31n_1v12v169zfv829p_v_80000gn/T/pip-build-f51KhW/mysqlclient/setup.py", line 17, in <module>
        metadata, options = get_config()
      File "setup_posix.py", line 54, in get_config
        libraries = [dequote(i[2:]) for i in libs if i.startswith('-l')]
      File "setup_posix.py", line 12, in dequote
        if s[0] in "\"'" and s[0] == s[-1]:
    IndexError: string index out of range

    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /private/var/folders/y_/c31n_1v12v169zfv829p_v_80000gn/T/pip-build-f51KhW/mysqlclient/

Answer 1

今天这对我有用，在使用 brew install mysql 使用 Homebrew 安装 MySQL 服务器之后：

MYSQLCLIENT_CFLAGS=`pkg-config mysqlclient --cflags` \
  MYSQLCLIENT_LDFLAGS=`pkg-config mysqlclient --libs` \
  pip install mysqlclient

brew install/upgrade/reinstall mysql
brew install mysql-client
export PATH="/usr/local/opt/openssl/bin:$PATH"
export LDFLAGS="-L/usr/local/opt/openssl/lib"
export CPPFLAGS="-I/usr/local/opt/openssl/include"
pip install mysqlclient
works perfectly

Answer 3

如果您不打算在您的计算机中安装 mysql，请安装 mysql-client 而不是 mysql

brew install mysql-client

echo 'export PATH="/usr/local/opt/mysql-client/bin:$PATH"' >> ~/.bash_profile

source ~/.bash_profile

pip install mysqlclient

导出 LDFLAGS="-L/usr/local/opt/openssl/lib"

export CPPFLAGS="-I/usr/local/opt/openssl/include"

Answer 4

我需要以下内容来构建/安装mysqlclient

brew install mysql-client
# mysql-client is not on the `PATH` by default
export PATH="/usr/local/opt/mysql-client/bin:$PATH"
# openssl is not on the link path by default
export LIBRARY_PATH="$LIBRARY_PATH:/usr/local/opt/openssl/lib/"

那我可以pip wheel mysqlclient / pip install mysqlclient 成功

对于 Mac： 首先从 App Store 下载 Xcode，从 https://dev.mysql.com/downloads/workbench/ 下载 MySqlWorkbench

在终端中运行以下命令，

$ brew install mysql

$ export PATH=$PATH:/Applications/MySQLWorkbench.app/Contents/MacOS

$ xcode-select --install

$ pip install mysqlclient

Answer 6

使用brew安装mysql并将其添加到路径中：

$ brew install mysql

$ export PATH=/usr/local/mysql/bin:$PATH

$ sudo ln -s /usr/local/mysql/lib/libmysqlclient.18.dylib /usr/local/lib/libmysqlclient.18.dylib

$ pip install mysqlclient

Answer 7

我也遇到过这个问题，下面是我的步骤：

1.brew install mysql-connector-c

2.pip install mysqlclient

然后遇到这个错误，我已经跟踪了源代码，但是解决了这个然后又出现了另一个错误。

所以我改变了安装mysqlclient的方式，只是：

1.brew install mysql

2.pip install mysqlclient

这对我有用，没有发生任何错误。
