I’m using macOS11(beta), BigSur.
I think BigSur is cool but, I have faced many issues that I haven’t had before.
- Crash so many times
- Cannot install some software as well as macOS 10 In this article, I will show you how I could install python via
pyenvon BigSur. The following was the issue I had.

According to the wiki on GitHub, basically this issue will be solved by installing zlib.
So, I installed zlib via Homebrew
<span>$ </span>brew <span>install </span>zlib<span>$ </span><span>export </span><span>LDFLAGS</span><span>=</span><span>"-L/usr/local/opt/zlib/lib"</span><span>$ </span><span>export </span><span>CPPFLAGS</span><span>=</span><span>"-I/usr/local/opt/zlib/include </span><span>$ </span>brew <span>install </span>zlib <span>$ </span><span>export </span><span>LDFLAGS</span><span>=</span><span>"-L/usr/local/opt/zlib/lib"</span> <span>$ </span><span>export </span><span>CPPFLAGS</span><span>=</span><span>"-I/usr/local/opt/zlib/include </span>$ brew install zlib $ export LDFLAGS="-L/usr/local/opt/zlib/lib" $ export CPPFLAGS="-I/usr/local/opt/zlib/include

Maybe some of you will need to install the following.
<span>$ </span>brew <span>install </span>readline xz<span>$ </span>brew <span>install </span>readline xz$ brew install readline xz

However, I got the same error again… I did some research on this issue.
I also tried reinstalling Xcode command-line tools, but it didn’t solve the issue…
Then finally, I figured out the solution.
There are 2 steps to resolve this issue.
Step 1 Align command-line tools
In my case, I use Xcode-beta.app
I needed to check the version of command-line tools matches Xcode.
- Open Xcode-beta.app
- Go to Preference > Locations
- Select the right version of command-line tools (* I use Xcode-beta.app version 5 and command-line tools version 5)
Step 2 Install python
In this case, I installed 3.8.0. If you want to install a different version, you will need to change the version in the following command.
