Ubuntu or Ubuntu-based release users now have the opportunity to use GoogleChrome's Linux version. Through PPAforUbuntuChromiumDailyBuilds, you can run the Chrome browser's preview version on Ubuntu.

Download the code management tool depot_tools, which is a client tool that Google uses to obtain SVN code encapsulated in Python. Decompress depot_tools to the directory e:/Chrome/depot_tools (do not include Chinese characters or spaces in the directory path), and add the directory path to the PATH environment variable. Then, create the environment variable gyp_msvs_version = 2005 (or 2008). The purpose of this environment variable is to ultimately produce the pro
