问题描述
我刚刚在macOS Catalina上安装了pyenv，并通过命令await Future.delayed(Duration(seconds: 1),(){ //open or close });得到以下错误消息：
pyenv doctor日志文件如下：

我使用Homebrew安装了pyenv和pyenv-virtualenv，并通过克隆GitHub存储库安装了更新和Doctor附加组件。命令/var/folders/tl/_2700jnn5vj0q5ryygn4c4ww0000gp/T/python-build.20201021121358.92440 ~

提供以下输出：
brew list我的.zshrc文件如下所示：
fig pyenv-virtualenv xz
[email protected] pyenv readline
和.zshenv文件如下：
if command -v pyenv 1>/dev/null 2>&1; then
eval "$(pyenv init -)"
fi
我不确定其他信息是否相关，因此您可以在评论中要求更多信息。
解决方法
问题是与Homebrew一起安装的OpenSSL，但它“未符号链接到/ usr / local，因为macOS提供了LibreSSL”。我是通过运行命令brew info openssl来了解这一点的，该命令说
[email protected]: stable 1.1.1h (bottled) [keg-only]
Cryptography and SSL/TLS Toolkit
https://openssl.org/
/usr/local/Cellar/[email protected]/1.1.1h (8,067 files,18.5MB)

From: https://github.com/Homebrew/homebrew-core/blob/HEAD/Formula/[email protected]
License: OpenSSL
==> Caveats
A CA file has been bootstrapped using certificates from the system
keychain. To add additional certificates,place .pem files in
/usr/local/etc/[email protected]/certs
and run
/usr/local/opt/[email protected]/bin/c_rehash
[email protected] is keg-only,which means it was not symlinked into /usr/local,because macOS provides LibreSSL.
If you need to have [email protected] first in your PATH run:
echo 'export PATH="/usr/local/opt/[email protected]/bin:$PATH"' >> ~/.zshrc
For compilers to find [email protected] you may need to set:
export LDFLAGS="-L/usr/local/opt/[email protected]/lib"
export CPPFLAGS="-I/usr/local/opt/[email protected]/include"
For pkg-config to find [email protected] you may need to set:
export PKG_CONFIG_PATH="/usr/local/opt/[email protected]/lib/pkgconfig"
此修复程序可以在“警告”下的此处找到。我在我的〜/ .zshrc文件中添加了导出LDFLAGS和CPPFLAGS行，并且pyenv doctor命令不再给出任何错误。
