+# The following line removes TS installed by dtslint because it caused a failure on Node.js < 12.
+# dtslint in its current version installs typescript@next which is failing on older Node.js.
+# Using --localTs does not fix the issue because interpreter first gets the code of dtslint and its dependencies.
