vue upgrade also has this problem.
Sometimes vue add or vue upgrade command did not report errors, but it wrote unexpected bytes to svn control files, made the working dir unusable.
SVN control files should be ignored when reading and writing files.
'**/.svn/**' should be added to

vue-cli/packages/@vue/cli/lib/util/readFiles.js

ignore: ['**/node_modules/**', '**/.git/**'],
