协议缓冲区:版本更改 [英] Protocol Buffer: Version Change

问题描述

我不小心安装了 3.0.0 版，我的大部分文件自然会出现大量错误.现在我想把它带回 2.6.1.我已经下载并安装了 2.6.1，但是当我执行 protoc --version 时，它仍然显示 libprotoc 3.0.0，这是错误的.

I have accidentally installed version 3.0.0 and most of my files naturally gave tons of errors. Now I want to take it back to 2.6.1. I already downloaded 2.6.1 and installed, however when I do protoc --version it still shows libprotoc 3.0.0, which is wrong.

有没有办法将版本设置为 2.6.1 或者有没有办法卸载 3.0.0?

Is there a way to set the version to 2.6.1 or is there a way to uninstall 3.0.0?

推荐答案

想通了.应该删除 /local 和 /include 下有关 google 协议缓冲区的所有内容，然后简单地重新安装另一个版本.之后 protoc --version 显示新版本.

Figured it out. One should delete everything regarding google protocol buffers under /local and /include, , and then simple reinstall the other version. After that protoc --version shows the new version.
