Python安裝Mysql驅動出錯解決最新出爐

python中最連線mysql常用的驅動是

mysql-python ：mysql的c語言的驅動 mysql-connector：msql官方的驅動

pymysql：python語言的驅動

我這裡安裝的是 mysql-python

終端中執行

pip install mysql-python

運氣好的的話，直接就成功了，我遇到了一下問題，最終找到了解決方案，原因及解決方案如下，供參考

終端列印出：

collecting mysql-python downloading mysql-python-1.2.5.zip (108kb) 100% |████████████████████████████████| 110kb 30kb/s complete output from command python setup.py egg_info: sh: mysql_config: command not found traceback (most recent call last): file "", line 20, in file "/private/tmp/pip-build-np8j3v/mysql-python/ setup.py", line 17, in metadata, options = get_config() file "setup_posix.py", line 43, in get_config libs = mysql_config("libs_r") file "setup_posix.py", line 25, in mysql_config raise environmenterror("%s not found" % (mysql_config.path,)) environmenterror: mysql_config not found ----------------------------------------

command "python setup.py egg_info" failed with error code 1 in /private/tmp/pip-build-np8j3v/mysql-python

解決方法，執行：

ln -s /usr/local/mysql/bin/mysql_config /usr/local/bin/mysql_config

原因

找不到mysql_config一般是由於通過lnmp.org或者其他方式安裝mysql以後mysql_config是在/usr/local/mysql/bin/裡面，這裡面的檔案不是在任意位置都可以訪問的，而指令是

將mysql_config鏈結到/usr/local/bin目錄下

參考一條命令解決mysql_config not found

出錯資訊為：

traceback (most recent call last):
file "manage.py", line 4, in from  models import user
file "/users/tengfei/pycharmprojects/mysql/models.py", line 1, in import  mysqldb
file "/library/python/2.7/site-packages/mysqldb/__init__.py", line 19, in import _mysql
importerror: dlopen(/library/python/2.7/site-packages/_mysql.so, 2): library not loaded: libmysqlclient.18.dylib
referenced from: /library/python/2.7/site-packages/_mysql.so
reason: image not found

解決：

pip install --upgrade pip

修改 os x 環境變數：開啟終端，在終端中使用 vim 開啟「~/.bash_profile」，如果沒有安裝 vim，那就顯示隱藏檔案用文字編輯器開啟，具體操作這裡就不複述了。在 .bash_profile 中新增以下內容

path="/usr/local/mysql/bin:$" export path export dyld_library_path=/usr/local/mysql/lib/ export versioner_python_prefer_64_bit=no

export versioner_python_prefer_32_bit=yes

其中 versioner_python_prefer_64_bit 和 versioner_python_prefer_64_bit 根據自己安裝的 mysql 進行選擇。

參考：mysqldb（即 mysql-python 包）在 os x 中安裝指南

solving library not loaded: libmysqlclient.18.dylib when importing mysqldb on lion

mac os + mysql-python-1.2.3: importerror | library not loaded | libmysqlclient.16.dylib

執行pip install mysql-python後的出錯資訊如下：

這是在虛擬環境中見到的

^compilation terminated.

error: command 'x86_64-linux-gnu-gcc' failed with exit status 1

----------------------------------------
command "/home/tengfei/api01/test/testto/todo-orm/venv/bin/python -u -c "import setuptools, tokenize;__file__='/tmp/pip-build-w6mp1w/mysql-python/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /tmp/pip-jg7ekf-record/install-record.txt --single-version-externally-managed --compile --install-headers /home/tengfei/api01/test/testto/todo-orm/venv/include/site/python2.7/mysql-python" failed with error code 1 in /tmp/pip-build-w6mp1w/mysql-python/

原因是：一些依賴包沒有安裝，注意這也是很多實用pip執行安裝擴充套件的時候，常見的錯誤

apt-get build-dep python-lxml sudo pip install lxml --upgrade

pip install mysql-python
