Please I am installing watchman for so that I can setup my React Native environment on MacBook Pro early 11 with Catalina 10.15.5.

All efforts to successfully install watchman has been abortive. Could anyone please help me? I have tried the command “brew install watchman” but it would complain of Folly and C.make during the installation. I have tried to install watchman through MacPort using the following MacPort documentation…

1. unzip watchman-*-linux.zip
2. cd watchman-vYYYY.MM.DD.00-linux
3. sudo mkdir -p /usr/local/{bin,lib} /usr/local/var/run/watchman
4. sudo cp bin/* /usr/local/bin
5. sudo cp lib/* /usr/local/lib
6. sudo chmod 755 /usr/local/bin/watchman
7. sudo chmod 2777 /usr/local/var/run/watchman

The step 4 AND 5 are wrong in the above step as the terminal showed that bin/* and lib/* are wrong and there I am stuck.

Is there anyone who can give me a practical proven guide on installing watchman on Mac Catalina 10.15.5 through Homebrew or MacPort?

I appreciate your efforts in advance

  • Welcome to Ask Different. Steps 2 and 3 look like they require you to change them after understanding the intent. Did you paste them in order without any changes?

  • MacPorts reports watchman does not work with Catalina. See here. Also, it probably does help that the MacBook Pro early 2011 model does not officially support macOS Catalina. Commented Jul 9 at 19:38
