在 mac 上安裝 mysqlclient 遇到了一些問題，查找資料很多人都遇到了同樣的問題。通過資料和試驗，成功了。這里記錄一下，希望幫到遇到同樣問題的人。
本人使用python3， 安裝步驟如下：
brew install mysql-connector-c pip3 install mysqlclient
當執行 pip3 install mysqlclient 是出現錯誤：
➜ /usr/local/Cellar/mysql-connector-c/6.1.11/bin >pip3 install mysqlclient Collecting mysqlclient Using cached mysqlclient-1.3.12.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/2w/56bgkvqd1xldl56fx_gx_fg00000gn/T/pip-build-f9admsgv/mysqlclient/setup.py", line 17, in <module> metadata, options = get_config() File "/private/var/folders/2w/56bgkvqd1xldl56fx_gx_fg00000gn/T/pip-build-f9admsgv/mysqlclient/setup_posix.py", line 54, in get_config libraries = [dequote(i[2:]) for i in libs if i.startswith('-l')] File "/private/var/folders/2w/56bgkvqd1xldl56fx_gx_fg00000gn/T/pip-build-f9admsgv/mysqlclient/setup_posix.py", line 54, in <listcomp> libraries = [dequote(i[2:]) for i in libs if i.startswith('-l')] File "/private/var/folders/2w/56bgkvqd1xldl56fx_gx_fg00000gn/T/pip-build-f9admsgv/mysqlclient/setup_posix.py", line 12, in dequote if s[0] in "\"'" and s[0] == s[-1]: IndexError: string index out of range ----------------------------------------
解決方案：mysql_config
執行：vim mysql_config，搜索 libs，或者114行，替換為115行即可
112 # Create options 113 libs="-L$pkglibdir" 114 #libs="$libs -l " ##源代碼 115 libs="$libs -lmysqlclient -lssl -lcrypto " ##修改成這樣
再次執行pip3 install mysqlclient，成功了。如下所示：
➜ /usr/local/Cellar/mysql-connector-c/6.1.11/bin >pip3 install mysqlclient Collecting mysqlclient Using cached mysqlclient-1.3.12.tar.gz Building wheels for collected packages: mysqlclient Running setup.py bdist_wheel for mysqlclient ... done Stored in directory: /Users/kk/Library/Caches/pip/wheels/df/bb/60/bf7c315cbe163515db1c846e4ffa5557dd785c82e82f3492e8 Successfully built mysqlclient Installing collected packages: mysqlclient Successfully installed mysqlclient-1.3.12
