linux下node项目报404错误

错误代码提示：

Or maybe you don't have permissions to access the .tmp directory?
test-4 (err): e.g., /usr/jsdir/test/.tmp ?

test-4 (err):
test-4 (err): If you think this might be the case, try running:
test-4 (err): sudo chown -R YOUR_COMPUTER_USER_NAME /usr/jsdir/test/.tmp

错误提示的不是很清楚吗？权限不足
