Question

我使用Mac（OS X 10.11.5）。我想为python安装模块pymssql。在Terminal.app，我输入了sudo -H pip install pymssql，pip install pymssql，sudo pip install pymssql。但是错误发生了。

目录/Users/janghyunsoo/Library/Caches/pip/http或其父目录不属于当前用户，并且已禁用缓存。请检查该目录的权限和所有者。如果使用pip执行sudo，您可能需要sudo -H标记。

        You can install FreeTDS with Homebrew or MacPorts, or by downloading
        and compiling it yourself.

Answer 1

最高投票解决方案对我不起作用，因为brew没有自己链接旧版本的freetds。我这样做是为了解决这个问题：

brew unlink freetds; 
brew install freetds@0.91;
brew link --force freetds@0.91

Answer 2

我能够通过在运行pip安装之前通过Homebrew恢复到旧版本的FreeTDS来解决这个问题。

brew unlink freetds; brew install homebrew/versions/freetds091

解决方案是由andrewmwhite在： https://github.com/pymssql/pymssql/issues/432

Answer 3

在http://gree2.github.io/python/setup/2017/04/19/python-instal-pymssql-on-mac上逐步安装pymssql，找到详细而简单的答案。

brew unlink freetds; brew install homebrew/core/freetds091
brew link --force freetds@0.91
pip install pymssql

Answer 4

＆＃34; brew install homebrew / python / pymssql＆＃34;也工作，但将安装旧版2.1.1。

Answer 5

找到了pip / python2和pip3 / python3的解决方案

问题：

在@siva和@himanshu解决方法适用于python2但不适用于python3之后，我无法从pip3获得成功的构建。

pip3 install pymssql

    ..._mssql.c:21155:15: error: use of undeclared identifier 'DBVERSION_80'
        __pyx_r = DBVERSION_80;
                  ^
    1 error generated.
    error: command 'clang' failed with exit status 1

您的问题不是许可问题，而是与pymssql相关代码的代码编译问题。

Here's the discussion，我在哪里找到Solution on github.

这已经有一段时间了，只是放在这里以提高知名度。

只需使用gitub中最新的pymssql版本：

    pip3 install git+https://github.com/pymssql/pymssql

也适用于python2

    pip install git+https://github.com/pymssql/pymssql

OR

    pip2 install git+https://github.com/pymssql/pymssql

我在Mac OS X (10.13.6) & Homebrew (1.7.1-62-gddbefee)上进行了多次测试。该命令适用于两种版本的freetds（0.91）或（1.00.94）

Answer 6

这在Mac上对我有用：

pip install cython

然后

pip install git+https://github.com/pymssql/pymssql.git

Answer 7

以上所有解决方案都可以正常工作。提醒您一点，pymssql pip install的setup.py希望Homebrew在/ sw安装了Freetds

if sys.platform == 'darwin':
    fink = '/sw'

这不是我机器上的情况，所以我不得不在这里使用工作：

手动下载pymssql的.tar文件
在setup.py文件中将其更改为将 fink 指向freetds位置
然后运行python setup.py install
