尝试重装Azure CLI、移除PATH中的Python相关路径后问题仍未解决。

解决方案 #

1. 清理现有Bicep二进制文件 #

打开文件资源管理器，导航到%USERPROFILE%\.azure\bin目录，删除其中的bicep.exe文件。

2. 手动下载匹配架构的Bicep二进制 #

下载对应Windows系统架构的Bicep可执行文件（64位系统选择x64版本，32位选择x86版本）。

3. 放置文件到指定目录 #

将下载好的bicep.exe复制到%USERPROFILE%\.azure\bin目录下。

4. 验证PATH配置 #

打开系统环境变量设置，确认%USERPROFILE%\.azure\bin已添加到PATH中，且该路径位于其他可能存在冲突的路径之前。

5. 测试命令 #

重启命令行终端，执行az bicep version验证是否恢复正常。

额外排查点 #

• 若问题依旧，检查杀毒软件是否拦截了bicep.exe的执行，可临时关闭杀毒软件后重试。
• 确认系统架构与下载的Bicep版本完全匹配，避免32位/64位不兼容问题。
