错误：无法为 pymssql 构建轮子，这是在 Mac M1 中安装基于 pyproject.toml 的项目所必需的

Question

我正在使用带有 M1 芯片的 MacBook，似乎很多东西都没有针对它进行优化。
pyodbc对我不起作用，所以我想使用pymssql 。
不过，当我尝试运行pip install pymssql时遇到了这个问题。

错误如下。

  Using cached pymssql-2.2.2.tar.gz (170 kB)

Answer 1

在尝试大量解决此问题的解决方案时，似乎对我有用。
我提供下面的代码来解决这个问题。

注意：根据您的系统更改路径。

1. brew install freetds
2. brew install openssl
3. export LDFLAGS="-L/opt/homebrew/Cellar/freetds/1.3.3/lib -L/opt/homebrew/Cellar/openssl@1.1/1.1.1l_1/lib"
4. export CFLAGS="-I/opt/homebrew/Cellar/freetds/1.3.3/include" 
5. pip install pymssql

只需运行上述命令，它应该可以解决您的问题，因为它对我有用。

Answer 2

运行以下命令解决了我的问题

$ brew install freetds openssl
$ echo 'export LDFLAGS="-L/opt/homebrew/opt/freetds/lib -L/opt/homebrew/opt/openssl@3/lib"' >> ~/.zshrc
$ echo 'export CFLAGS="-I/opt/homebrew/opt/freetds/include"' >> ~/.zshrc
$ echo 'export CPPFLAGS="-I/opt/homebrew/opt/openssl@3/include"' >> ~/.zshrc
$ source ~/.zshrc
$ pip3 install pymssql
