tauri在github上进行自动更新打包并发版过程，实战操作避坑

从网上找了很多很多的文章，结果还是入坑了，一个问题找了一天才解决：

Error A public key has been found, but no private key. Make sure to set `TAURI_PRIVATE_KEY` environment variable.

596 ELIFECYCLE Command failed with exit code 1.

597Error: Process completed with exit code 1.

想要让tauri应用自动升级，就要配置公私钥设置，官方文档：Updater | Tauri Apps

本地生成公私钥

mac和linux生成公私钥

pnpm tauri signer generate -w ~/.tauri/myapp.key

windows生成公私钥

pnpm tauri signer generate -w $HOME/.tauri/myapp.key

给tauri配置公私钥

在tauri.conf.json文件中开启自动升级，并将公钥添加到里面，设置你的升级信息json文件获取的url路径

json文件内容格式：

{
  "version": "v1.0.0",
  "notes": "Test version",
  "pub_date": "2020-06-22T19:25:57Z",
  "platforms": {
    "darwin-x86_64": {
      "signature": "Content of app.tar.gz.sig",
      "url": "https://github.com/username/reponame/releases/download/v1.0.0/app-x86_64.app.tar.gz"
    },
    "darwin-aarch64": {
      "signature": "Content of app.tar.gz.sig",
      "url": "https://github.com/username/reponame/releases/download/v1.0.0/app-aarch64.app.tar.gz"
    },
    "linux-x86_64": {
      "signature": "Content of app.AppImage.tar.gz.sig",
      "url": "https://github.com/username/reponame/releases/download/v1.0.0/app-amd64.AppImage.tar.gz"
    },
    "windows-x86_64": {
      "signature": "Content of app.msi.sig",
      "url": "https://github.com/username/reponame/releases/download/v1.0.0/app-x64.msi.zip"
    }
  }
}

设置环境变量

将TAURI_PRIVATE_KEY和TAURI_KEY_PASSWORD设置为环境变量

mac和linux：

export TAURI_PRIVATE_KEY="content of the generated key"
export TAURI_KEY_PASSWORD="password"

windows：

set TAURI_PRIVATE_KEY="content of the generated key"
set TAURI_KEY_PASSWORD="password"

powershell:

$env:TAURI_PRIVATE_KEY="content of the generated key"
$env:TAURI_KEY_PASSWORD="password"

编写github action yml文件

我这里用的pnpm作为包管理工具的，你也可以使用yarn或者npm，但是我推荐使用pnpm
