Symptoms:
- When trying to enter Play mode, I receive the error "All compiler errors have to be fixed before entering playmode!".
Cause:
If any of the scripts in your Unity project have errors that do not allow Unity to compile the scripts, this error will be displayed. You will not be able to enter Play mode until all script errors are fixed.
You are importing assets made for different Unity versions.
You are opening a sample project on a different version of Unity than the original.
Resolution:
Any compiler error will prevent you from entering Play mode. You need to look at all errors showing in the console and fix them. Double-clicking the error in the console should show you the line of code with the issue. In most cases, you can search the error message online for related solutions.
Importing assets that contain scripts can result in the above error. Check the compatible Unity versions for the asset. The code may be outdated and no longer valid for more recent versions of Unity. In that case, you must manually fix all errors or download a more recent version of the asset.
If you're opening some of Unity's sample projects, please ensure that you open these in the original Unity version. This should prevent undesired behaviors like the error in question.
If the script is not being used, you could comment on the sections where the errors appear.
If you see the error, "All compiler errors have to be fixed before entering playmode!" on a fresh project without any changes or code, please consider updating to the most recent Unity version.
After all scripts are free of errors, Unity can compile the scripts and enter Play mode.

Might I be getting this error or a similar error if I had misspelled a key name in "input.GetKeyDown()"? Or maybe it's all-caps and it's supposed to be all lower-case?

I'm making a Roll a ball game using the video tutorials and I literally did everything he said to do, copied and corrected the codes and all, but it still says it. I'm crappy at coding myself, so I honestly have no idea what part I coded wrong....
I was able to find a fix for this 4 blank errors issues. See my post here:
https://forum.unity.com/threads/four-blank-errors-in-each-new-project.599980/
I was having the same issue with the four compiler errors showing up on all my projects out of the blue, even new ones. The solution for me was to update my assets package (remove the old one and download the new one). I was using an outdated one and when Unity updated the old sample assets were not compatible.
I cant get the PlayerController to goto Player in the Camera Script.
If thats not the problem, it says this in the errors.

Alternatively, if you believe that this may be a bug, please feel free to follow the process outlined at https://unity3d.com/unity/qa/bug-reporting for details on how to submit a bug report.
You are saying fix the problems I already know I have to do that not helpful
What worked for me in the 2d game tutorial which I found on another thread was to go to Edit > Project Settings > Player tab > Expand "Other Settings" and change the "Scripting Runtime Version*" from ".NET 3.5 equivalent (Deprecated)" to ".NET 4.x Equivalent" .
The original answer I found asked to do the reverse of this, but this is what worked on my iMac running Unity 2018.3.4. Hope it helps someone else.
Unity isn't even giving me any errors. I was able to enter playmode earlier and it suddenly stopped working right when I needed it to work for my school assignment. I attempted Jude McAuley Cotter's solution to no avail. (My game is also 3D)
go to Edit > Project Settings > Player tab > Expand "Other Settings" and change the "Scripting Runtime Version*" from NET 4.x Equivalent" to ".NET 3.5 "
this happens to me, by only opening Unity, why does this happens? it's because of my computer?
Hi Eduardo,
I've had a look into this and from what I can see, the error you are getting is part of a bug with the particular version of Unity that you are using.
If you upgrade to a patch higher than what you have now, the error should disappear. In the event that it does not, please do not hesitate to come back to me.
I think you didnt installed all the standard assets check in console what is the problem and then I also had a problem of this same That was I didnt installed crossplatform . Sorry for my english.
Hi,
Everything was working perfect, and then I changed the build settings from PC, Mac and Linux to mobile. Suddenly it didn't work. Changed back to PC, Mac and Linux, and still. It says I have to resolve all compiler errors, but there are none. I also can't see my console anymore for some reason.
I had problem in windows 7, so I found how to fix 4 blank error problem, you need only update the windows and then all wil lwork correct without errors..
And addition I want to say when you install unity on unityhub after installation you can see that writing sentence about update windows kb231345( numbers not real I forgot ) so this is your problem, I think most users made dismiss and not see this, and this is problem blank error,thanks all, hope this will help more users.
OOH THANKS MARUU <3 <3 i love you
Unity is showing this error in every script even when i am using standard assets or any asset this error cames (unity 2019.1)
ok this is a problem why is this code wrong?:
using UnityEngine;
public class MovementScript : MonoBehaviour
{
public Rigidbody rb;
public float ForwardForce = 2000f;
// Update is called once per frame
void FixedUpdate()
{
rb.AddForce(0, 0, ForwardForce * Time.deltaTime);
if (Input.GetKey("d"))
{
rb.AddForce(
500, *Time.deltaTime, 0, 0);
}
}
}
For Linux Ubuntu the fix is:

The Ubuntu fix worked for me.
Thnx Dorin for Ubuntu solution.
it is very easy at the first time do with me step by step
go to control panel > Region > Administrative > change System local > change to English unites state and restart windows
you will not get any error when you create new c# script
thanks

Is it possible to turn off this feature? I am trying to make an intentionally broken game and I would like to be able to run with programming errors
I was getting this error for the empty project.
@Dorin GRIGORE. Thanks your fix worked perfectly for,
Unity 2019.2.17f

Kubuntu 19.04
Same as everyone else. All I have is some basic terrain and I get this error
Library\PackageCache\com.unity.render-pipelines.universal@7.1.8\Editor\UniversalRenderPipelineCameraEditor.cs(1049,57): error CS0535: 'UniversalRenderPipelineCameraContextualMenu' does not implement interface member 'IRemoveAdditionalDataContextualMenu<Camera>.RemoveComponent(Camera, IEnumerable<Component>)'
I literally have not touched a piece of code, what do I do? I would love to actually do this tutorial.
This is a link to the exact tutorial that I am doing
