Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.
Alternatively, you may set the environment variables LIBEVENT_CFLAGS
and LIBEVENT_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
pg--12版本
难道pgbouncer ,libevent 的版本和pg-12 不兼容吗？
The error message "No package 'libevent' found" typically occurs when you're trying to compile or install software that requires the libevent library, but it is not installed on your system. Here's how you can resolve it based on your operating system:
On Ubuntu/Debian-based systems:
- Open a terminal and run the following command to install the
libeventdevelopment package:bashCopy Code
sudo apt-get update sudo apt-get install libevent-dev复制
On Fedora/RHEL/CentOS-based systems:
- Use the
dnforyumpackage manager to install the library:
Or for older versions of CentOS/RHEL:bashCopy Code
sudo dnf install libevent-devel复制bashCopy Code
sudo yum install libevent-devel复制
On macOS (using Homebrew):
- If you don't have Homebrew installed, install it first. Otherwise, you can directly install
libeventusing the following:bashCopy Code
brew install libevent复制
On Windows:
You may need to manually download and install
libeventfor Windows. Alternatively, if you are using a package manager like MSYS2 or vcpkg, you can installlibeventthrough them:For MSYS2:
bashCopy Code
pacman -S mingw-w64-x86_64-libevent复制For vcpkg:
bashCopy Code
vcpkg install libevent复制
After installing the required package, you can try the installation or compilation again, and the error should no longer appear.
