【问题描述】：
我正在尝试将 unixODBC 添加为供应商应用程序依赖项，按照此处概述的注释：https://github.com/cloudfoundry/python-buildpack/issues/34，但我仍然遇到致命错误：
sql.h: 没有这样的文件或目录。
我在下面创建了一个最小的、可验证的、完整的脚本，以方便读者重现我的问题：
mkdir new_app
cd new_app
cat <<EOF>requirements.txt
pyodbc==4.0.17
EOF
cat <<EOF>manifest.yml
applications:
- name: pyodbc-test
memory: 128M
EOF
cat <<EOF>.profile
export LD_LIBRARY_PATH=\$LD_LIBRARY_PATH:/app/vendor/unixodbc/lib
EOF
sudo docker run -it --rm -v ${PWD}:/app cloudfoundry/cflinuxfs2 bash -c \
"wget ftp://ftp.unixodbc.org/pub/unixODBC/unixODBC-2.3.4.tar.gz; tar xzf unixODBC-2.3.4.tar.gz; cd unixODBC-2.3.4; ./configure --prefix=/app/vendor/unixodbc; make; make install;"
接着是：
sudo chown -R ${USER}:${USER} vendor/
pip3 download -r requirements.txt -d vendor/
cf push
cf push 输出：
...

这里有一个类似的问题：pyodbc install on IBM Bluemix server error，但是这个问题与这个问题的不同之处在于它非常通用，而这个问题是关于同一主题但涉及一组非常具体的构建步骤。
更新：这是基于接受的答案的更新脚本：
mkdir new_app
cd new_app
cat <<EOF>environment.yml
name: pyodbc-test
dependencies:
- pyodbc
EOF
cat <<EOF>manifest.yml
applications:
- name: pyodbc-test
memory: 128M
EOF
cf push
