升级颤振后命令不起作用

Question

由于min v1.5 sdk插件需要，我使用flutter升级，但是由于我不能使用命令...我没有找到bash命令，

我尝试手动下载 1.5 sdk 并替换以前的文件夹，当我使用颤振医生他说我有 1.2.1 ...我试图重新升级但我有这个错误：

Your flutter checkout has local changes that would be erased by upgrading. If you want to keep these changes, it is
recommended that you stash them via "git stash" or else commit the changes to a local branch. If it is okay to remove
local changes, then re-run this command with --force.

Answer 1

为简单起见，您可以将flutter sdk提取到文件夹'c：\ Flutter'然后设置路径

Windows | iOS

删除您创建的旧 Flutter SDK 文件夹。然后按照步骤illustrated here 将Android Studio 指向新的Flutter SDK 安装。

Answer 2

在我的情况下，Flutter 有未分级的更改（因为它使用 git），所以我需要存储或重置它以便能够升级它。

转到flutter的路径并：

# cd flutter_path/
git add -A
git reset --hard

您也可以使用--force 来升级它。

flutter upgrade --force

Answer 3

我遇到了同样的问题。这可能是因为我将 Flutter SDK 安装在 E:\ 目录而不是默认的 C:\ 目录中。 我就是这样解决的，

1：检查 Flutter Sdk 的位置。您可以通过创建“新项目->Flutter->Flutter Sdk”来执行此操作（如果您安装并配置了 Flutter Sdk，则此方法有效，如果您没有安装它，您可以单击相同的安装 Sdk 选项“新的 Project->Flutter" 窗口)。

2：然后通过转到 IDE 的右下角然后单击终端来打开终端。

3：通过键入“cd _yourSdkLocation\bin”将目录更改为 Flutter sdk 的 bin 位置。这里将“_yourSdkLocation”替换为你的flutter Sdk所在的目录地址。

4：然后运行“flutter upgrade --force”

Answer 4

在 Android Studio 或 CMD 中打开终端并粘贴

flutter upgrade --force

Answer 5

在终端中，使用命令

• source .bash_profile
  

• 然后运行，

  flutter upgrade --force
  

删除flutter目录的改动，会升级到最新的flutter版本
