1.SSL_ERROR_SYSCALL in connection to github.com:443 報(bào)錯(cuò)
[!] Error installing TensorFlowLiteSwift

解決方案：
如果鍵入github.com:443后進(jìn)入的Github不是當(dāng)前git config --global -l里當(dāng)前賬號(hào)的倉庫缚窿，那就退出登錄觉渴。如果出現(xiàn)的是Github的登錄界面侍筛，那就登錄Github尺铣。

增加github.global.ssl.fastly.net和github.com的映射
獲取Github相關(guān)網(wǎng)站的ip
訪問https://www.ipaddress.com，拉下來肠槽，找到頁面中下方的“IP Address Tools – Quick Links”
分別輸入github.global.ssl.fastly.net和github.com滓鸠，查詢ip地址
在hosts文件里添加：
# github
199.232.69.194 github.global.ssl.fastly.net
140.82.112.4 github.com
最后命令行輸入：ipconfig /flushdns（更新DNS緩存）
