I want to install the mediasoup but after the “npm install mediasoup” command I get this error:

```auto
98 info run mediasoup@3.9.1 postinstall node_modules/mediasoup node npm-scripts.js postinstall
99 info run mediasoup@3.9.1 postinstall { code: 1, signal: null }

```

How can I fix?

Thank you

Did you follow all of the latest Windows installation instructions?: [mediasoup :: Installation](https://mediasoup.org/documentation/v3/mediasoup/installation/)  
I don’t see what is wrong in your snippet, it just failed for no apparent reason it seems.

Yes, I did. I think it supposed to success, but failed . Maybe I did some wrong Installation ？  
I don’t know every command to check out my Installation .  
Like this:

```auto
gcc --version

```

```auto
PS H:\workspace\test> gcc --version
gcc.exe (MinGW.org GCC-6.3.0-1) 6.3.0

or:

```auto
vcvars64

```

```auto
PS H:\workspace\test> vcvars64

```

would you tell me?  
Thanks!

GCC is irrelevant here, you are supposed to use MSVC. What is the `make` that is available there? It must be GNU Make from MSYS.

It seem to be right.

As I already said, it is important to make sure correct make version is used, while you provided all information except make version.

Sorry，I have provided the path:

```auto
C:\MinGW\msys\1.0\bin\make.exe

```

I just don’t konw how to get the make version…

```auto
PS H:\workspace> make --version
PS H:\workspace> make -v
PS H:\workspace> make --help
PS H:\workspace>

```

What command shuld I use?  
Is this can provide something userful:

`make -v` should provide you an output saying it is GNU Make from MSYS. If it doesn’t, you likely didn’t follow all instructions and didn’t add `C:\MinGW\msys\1.0\bin\` to `Path`.

I did…

I run the command make -v using Command Prompt get this:

 ![{CEC449AC-5F36-4FD1-B969-1403E77A2CA8}](https://global.discourse-cdn.com/free1/uploads/mediasoup/original/2X/7/78c6d01093a88ab99f6940fbcd9f5ab10a9b7f35.png)  
It means：

```auto
Code execution cannot continue because msys-1.0.dll cannot be found. A new installation may solve the problem

```

This could be the reason why I failed.

After I tried reinstall again many times…

```auto

check the environment find :

In fact, I have updated visual studio a few hours ago（try to fix something?） :  
C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.29.30133\bin\Hostx64\x64

I thought I should succeed this time:

There is also a note in the instructions about Python errors too. Just read and follow everything top to bottom without skipping and without diverting from instructions or you are on your own.

Thanks a lot ! Feel at ease with your help.  
I will try install Microsoft Visual Studio 2017 to handle the ERROR: Compiler cl can not compile programs.  
At least the problem is obvious。  
Thank you again!
