+```
+
+### Reason
+
+It has nothing to do with skywalking.
+According to https://github.com/sass/node-sass/issues/1176, if you live in countries where requesting resources from `github` and `npmjs.org` is very slowly, some precompiled binaries for dependency `node-sass` will fail to be downloaded during `npm install`, then npm will try to compile them itself. That's why `python2` is needed.
+
+### Resolve
+#### 1. If you live in China, please edit `skywalking\apm-webapp\pom.xml`
+Find
+```
+<configuration>
+ <arguments>install --registry=https://registry.npmjs.org/</arguments>
+</configuration>
+```
+Replace it with
+```
+<configuration>
+ <arguments>install --registry=https://registry.npm.taobao.org/ --sass_binary_site=https://npm.taobao.org/mirrors/node-sass/</arguments>
+</configuration>
+```
