On Windows : :Go build is failing with error ./go-python.h:4:10: fatal error: Python.h: No such file or directory #include "Python.h"
The error message you encountered, fatal error: Python.h: No such file or directory
, indicates that the Go build process cannot find the required Python.h
header file. This issue commonly occurs when the Go build environment is not properly configured with the necessary dependencies for building Go code that interacts with Python.
To resolve this error, you need to ensure that the Go build environment can locate the Python.h
header file. Here are the steps you can follow:
Install Python development headers: Make sure you have the Python development headers installed on your system. The exact package name may vary depending on your Python version and distribution. For example, on Ubuntu, you can install the headers with the following command:
bashsudo apt-get install python3-dev
Set CGO_ENABLED environment variable: Set the
CGO_ENABLED
environment variable to1
. This enables the Go build process to use CGo (C compiler-based Go bindings).bashexport CGO_ENABLED=1
Set CGO_CFLAGS environment variable: Set the
CGO_CFLAGS
environment variable to the path where thePython.h
header file is located. You need to provide the include directory path. The location can vary depending on your system and Python installation. For example, if you are using Python 3 on Ubuntu, the command could be:bashexport CGO_CFLAGS="-I/usr/include/python3.8"
Replace
/usr/include/python3.8
with the appropriate include directory path for your Python installation.Rebuild your Go code: After setting the environment variables, try rebuilding your Go code using the
go build
command or any other relevant Go build command. This should allow the Go build process to locate thePython.h
header file successfully.
Ensure that you have the necessary permissions to install packages and modify environment variables on your system.
By following these steps, you should be able to resolve the fatal error: Python.h: No such file or directory
error and successfully build your Go code that interacts with Python.
