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 fatal error :
sql.h: No such file or directory.
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;"
其次是:
sudo chown -R ${USER}:${USER} vendor/
pip3 download -r requirements.txt -d vendor/
cf push
cf 推送输出:

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:这是基于已接受答案的更新脚本:
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
最佳答案
src/pyodbc.h:56:17: fatal error: sql.h: No such file or directory #include
您的设置通常看起来不错,但是当 pip
在暂存期间运行时,构建工具仍然无法找到库 header 。 header 在那里,因为您将它们包含在 vendor/
目录中,但它不知道它们在那里,因为 python 模块的构建脚本不会在该位置查找它们.
我不知道有什么方法可以让它在不修改构建包的情况下在非标准位置查找 header ,因为 you need to send additional arguments到 pip
。
一些人建议设置 CPATH
和/或 C_INCLUDE_PATH
环境变量,因为这些应该被 gcc
获取,但是在我的测试,这些都被忽略了。
最后,我认为最好的选择是使用 Conda 安装 pyodbc。以下是您的处理方式。
- 将
environment.yml
添加到项目的根目录。 - 在其中添加以下内容:
name: pyodbc-test
dependencies:
- pyodbc
- 运行
cf push
。
构建包应该在暂存期间运行,安装 miniconda,然后使用 conda 安装依赖项,特别是 pyodbc。
希望对您有所帮助!
