【未解决】mac中安装python3的多个不同版本
期间，去安装pyenv install 3.5.2，结果报错：

为了后续可能用到，再去：
1 | vim ~/.bashrc |
加上：

结果问题依旧

1 2 | ➜ ~ xcode-select -vxcode-select version 2354. |
怀疑是之前虽然安装了zlib，也给.bashrc加了变量，但是没生效。
所以再去生效：
1 2 3 4 5 6 7 | ➜ ~ source ~/.bashrc➜ ~ echo $LDFLAGS -L/usr/local/opt/zlib/lib➜ ~ echo $CPPFLAGS -I/usr/local/opt/zlib/include➜ ~ echo $PKG_CONFIG_PATH /usr/local/opt/zlib/lib/pkgconfig |
然后再去：
1 | pyenv install 3.5.2 |
结果：可以了：
1 2 3 4 5 6 7 8 9 10 | ➜ ~ pyenv install 3.5.2python-build: use openssl from homebrewpython-build: use readline from homebrewDownloading Python-3.5.2.tar.xz...-> https://www.python.org/ftp/python/3.5.2/Python-3.5.2.tar.xzInstalling Python-3.5.2...patching file Lib/venv/scripts/posix/activate.fishpython-build: use readline from homebrewWARNING: The Python sqlite3 extension was not compiled.

即可。
【总结】
此处mac中：
1 | pyenv install 3.5.2 |
报错：
zipimport.ZipImportError: can’t decompress data; zlib not available
原因：
mac中缺少zlib，（编译期间）找不到zib
解决办法：
安装zlib，且要加到环境变量中，要让（编译）能找到zlib
（1）安装zlib
1 | brew install zlib |
（2）加上合适的环境变量
编辑~/.bashrc
1 | vim ~/.bashrc |
（在最后）加上：
1 2 3 4 5 6 7 | # For compilers to find zlib you may need to set:export LDFLAGS="${LDFLAGS} -L/usr/local/opt/zlib/lib"export CPPFLAGS="${CPPFLAGS} -I/usr/local/opt/zlib/include"# For pkg-config to find zlib you may need to set:export PKG_CONFIG_PATH="${PKG_CONFIG_PATH} /usr/local/opt/zlib/lib/pkgconfig" |
让变量生效：
1 | source ~/.bashrc |
【可选】确认变量的确生效：
1 2 3 4 5 6 | ➜ ~ echo $LDFLAGS -L/usr/local/opt/zlib/lib➜ ~ echo $CPPFLAGS -I/usr/local/opt/zlib/include➜ ~ echo $PKG_CONFIG_PATH /usr/local/opt/zlib/lib/pkgconfig |
