每次我尝试像往常一样使用“yarn start”启动我的项目时，我都会得到“Command failed with exit code 127”错误。我已经意识到我开始得到这个错误，一旦我更新我的iOS到蒙特利v12.6.1。我的节点版本与它看起来的yarn不兼容。
我试过什么来解决这个问题：

• 我已尝试升级/更新我的节点版本。
• 我已经手动卸载了node/npm和yarn，并使用node版本16.0.0重新安装它们
• 我已经删除了node_modules和package_lock.json
• 我已经运行了命令“yarn”和其他所有更新/升级命令

我尝试过的一切都失败了。
以下是Yarn错误日志：
