将我的go安装文件夹升级到Go 1.14

sudo tar -C /usr/local -xzf go1.14.linux-amd64.tar.gz

每次尝试构建程序时，我都会收到运行时错误：

开发人员大家好，我是 git 新手，我有一些关于 GitHub 的问题。如果可以请回答。

• Q1）如果我的存储库是公开的并且我没有为我的帐户设置ssh 密钥，任何人都可以推送到我的存储库吗？
• Q2）使用 HTTPS url 进行推送和拉取是否安全？
• Q3)为什么即使我没有设置任何ssh-key git 也不要求身份验证？
• Q4）我如何保护我的仓库不被外人看到，这样他们只能看到它而无法更改它？
