How to install a specific version of flow using brew

This time I will show you how to use brewInstallA specific version of flow, what are the precautions for using brew to install a specific version of flow, the following is a practical case, let’s take a look .

$ brew -v
Homebrew 1.2.0
$ flow version
Flow, a static type checker for JavaScript, version 0.45.0
$ flow
Launching Flow server for /Users/real/Desktop/reactPro/pro2
Wrong version of Flow. The config specifies version ^0.42.0 but this is version 0.45.0

You can also see the last place in my .flowconfig file:

[version]
^0.42.0

This means that the version of flow should be >=0.42.0 <0.43.0, so 0.45.0 is inappropriate. This requires downloading version 0.42.0.

Searched for some opinions on the Internet (brew installs a specific version):

brew install flow (the latest version is installed)

brew versions (obsolete)

brew tap homebrew/versions (obsolete)

Warning: homebrew/versions was deprecated. This tap is now empty as all its formulae were migrated.

npm install flow-bin@0.42.0 -g (It can be installed, but the actual effect is not seen)

When I installed flow, there was this prompt:

$ brew install flow

Already downloaded: /Users/real/Library/Caches/Homebrew/flow-0.45.0.sierra.bottle.tar.gz
==> Pouring flow-0.45.0.sierra.bottle.tar.gz
==> Caveats
Bash completion has been installed to:
 /usr/local/etc/bash_completion.d
zsh completions have been installed to:
 /usr/local/share/zsh/site-functions
==> Summary
�� /usr/local/Cellar/flow/0.45.0: 8 files, 6.4MB</p>
<p style="text-align: left;">It downloaded It is version 0.45.0, and what I need is version 0.42.0, so I downloaded it manually. </p>
<pre class="brush:php;toolbar:false">https://homebrew.bintray.com/bottles/flow-0.42.0.sierra.bottle.tar.gz

Then put the decompressed file into

/usr/local/Cellar/flow/

so that version 0.42.0 is installed. Then just pass

$ brew switch flow 0.42.0

. . A bit sad. . Thumbs up, brother. .
