I am using sagemath -9.2 and I have recently wanted to add the package "**plantri**" to my packages. I found a link to a similar question before. (
The link cannot be attached because:**Could not post, because your karma is insufficient to publish links**)

```
sage: !sage -i plantri
```

An error occurred during the installation process that prevented it from proceeding.

```
make[3345]: Entering directory '/opt/sagemath-9.2'

make[3345]: *** [Makefile:31: bootstrap] Error 127
```

My computer is windows10 64-bit system. I don't know how to solve this problem of installation.

In fact, the graph theory problem I encountered is as follows.

I 'd like to generate all **25-vertex 4 regular planar graphs that size of maximum face is 4**.
Of course it may not exist.

With the help of this computer software, I think there should be no problem, because I saw the following link, which contains such a paragraph.

Additionally, using plantri it has been established that there exist

no 4-regular planar graphs with 28vertices and similarly there are no 3-regular planar graphs with diameter 4 with between 20 and 30 vertices.

If there is someone who has successfully installed it, can you help me see if there is such a graph? Thanks in advance！
