我试图在新格式化的macos highsierra10.13.4上运行python3项目，首先运行 pipenv install 获取依赖项，但失败了。
具体来说，它无法安装依赖项的部分是mysqlclient部分。
此错误消息显示：

_mysql.c:1894:3: error: use of undeclared identifier 'my_bool'
              my_bool recon = reconnect;
              ^
_mysql.c:1895:58: error: use of undeclared identifier 'recon'
              mysql_options(&self->connection, MYSQL_OPT_RECONNECT, &recon);
                                                                     ^

==> Caveats
A CA file has been bootstrapped using certificates from the SystemRoots
keychain. To add additional certificates (e.g. the certificates added in
the System keychain), place .pem files in
  /usr/local/etc/openssl/certs

and run
  /usr/local/opt/openssl/bin/c_rehash

This formula is keg-only, which means it was not symlinked into /usr/local,
because Apple has deprecated use of OpenSSL in favor of its own TLS and crypto libraries.

If you need to have this software first in your PATH run:
  echo 'export PATH="/usr/local/opt/openssl/bin:$PATH"' >> ~/.bash_profile

For compilers to find this software you may need to set:
    LDFLAGS:  -L/usr/local/opt/openssl/lib
    CPPFLAGS: -I/usr/local/opt/openssl/include

我很沮丧，想卸载我所有的python安装，但我只是担心我可能会把mac搞砸，因为它依赖于预先构建的过时python版本。
如何正确安装依赖项？
