I'm trying (for hours now) to install the cargo crate diesel_cli for postgres. However, every time I run the recommended cargo command:
cargo install diesel_cli --no-default-features --features postgres
I wait a few minutes just to see the same build fail -> abort error, with this message:
note: LINK : fatal error LNK1181: cannot open input file 'libpq.lib'
error: aborting due to previous error
error: failed to compile `diesel_cli v1.4.1`, intermediate artifacts can be found at `C:\Users\<user name here>\AppData\Local\Temp\cargo-installUU2DtT`
Caused by:
could not compile `diesel_cli`.
I'm running postgres in a docker container and have the binaries on my C:\pgsql with the lib and bin directories both on the PATH so I can't figure out why it's not linking. What else could be required they didn't mention in the docs?
In my case the installation was successful but when I tried to run it this error occured. maybe this would work for others who have the same problem:
setx PQ_LIB_DIR "C:\Program Files\PostgreSQL\13\lib" (or any other path to your PostgreSQL lib)I had the same issue with WSL, if you're on Linux probably you could find PostgreSQL lib location and add it to your environment variables.
Adding the folder to the PATH variable didn't help, at least in my case, as by some reason it is not used in the /LIBPATH parameter passed to link.exe.
In my case it was C:\Users\<username>\.rustup\toolchains\stable-x86_64-pc-windows-msvc\lib\rustlib\x86_64-pc-windows-msvc\lib
You can see it in the beginning of the error message.
Copy libpq.lib in there and it will be used from there.
After installation diesel would require some other assemblies. Copy libcrypto-1_1-x64.dll, libiconv-2.dll and libssl-1_1-x64.dll into the folder showed after where diesel command execution
I had the same error on Ubuntu and for me the following install fixed the issue:
sudo apt install libpq-dev
