I install youcompleteme with some problems. My system is ubuntu 14.04LTS,vim version is 7.4.273, as I went to the last step ./install.py --clang-completer there would be error as follow. I tried many times, the problems were all the same. Looking forward to your help, thx a lot.

Which version of CMake are you using? Did you install the Python headers as instructed in the documentation:

sudo apt-get install python-dev

?

[hoseahsu]

It's the python's problem,it works,thx very much!

[MagnusBrzenk]

I found that cmake installed for a user with python3.8 (default installation) did not work on Ubuntu 20.04. When I removed it and ran sudo apt install cmake I was able to compile python3 install.py --all without further issue.

[bstaletic]

And what was the error? I have tried 20.04 when it was in beta and it worked.

[MagnusBrzenk]

@bstaletic The error was the same as given in this title, a highly non-descript "ERROR: The build failed"

[puremourning]

That is printed _after_ the actual error

Even the OP included the _actual_ error.

What what the _actual_ error ?

@bstaletic The following is copy/pasted directly from my terminal ssh-ed into a fresh install of Ubuntu Server 20.04 LTS Arm (on RPi4). I was given no cmake error.

The following seuqence fixed it though:

pip3 uninstall cmake
sudo apt install cmake
python3 install.py --all

[bstaletic]

You were supposed to install cmake with apt. I have no idea what cmake from pip is.
