【中文标题】当“颤振升级”时，我得到“权限被拒绝”错误【英文标题】：When " flutter upgrade", I get "Permission denied" error 【发布时间】：2020-09-28 01:41:04 【问题描述】：

我想用 Flutter 构建一个 Web 应用程序。我遵循了这个指示。 https://flutter.dev/docs/get-started/web 我使用 Windows 10、适用于 Linux 的 Windows 子系统、Debian 10。

我在~/development/目录下安装了Flutter SDK，并且已经设置好了路径。

我输入这个。

flutter channel beta

并得到这个结果。

Switching to flutter channel 'beta'...
git: From https://github.com/flutter/flutter
git:    5f21edf8b..b041144f8  stable         -> origin/stable

git:  * [new tag]             1.19.0-4.0.pre -> 1.19.0-4.0.pre
git: Switched to a new branch 'beta'
git: Branch 'beta' set up to track remote branch 'beta' from 'origin'.
Successfully switched to flutter channel 'beta'.
To ensure that you're on the latest build from this channel, run 'flutter
upgrade'

接下来，我输入这个。

flutter upgrade

那么，我明白了。

Downloading Dart SDK from Flutter engine ef9215ceb2884ddf520d321bcd822d1461330876...
mv: cannot move '/home/kazu/development/flutter/bin/cache/dart-sdk' to
'/home/kazu/development/flutter/bin/cache/dart-sdk.old': Permission denied

所以，我读了这个注释。 https://flutter.dev/docs/get-started/web#set-up

The flutter upgrade command silently fails when origin points to a personal fork. 
To validate that origin points to https://github.com/flutter/flutter.git, 
run the following commands in the root directory of your local copy of the 
https://github.com/flutter/flutter repository:

然后，我输入这个。

cd ~/development/flutter/
git remote get-url origin

然后我的终端返回了这个。

https://github.com/flutter/flutter.git

所以，我又试了一次。

flutter upgrade

我得到了同样的结果。

Downloading Dart SDK from Flutter engine ef9215ceb2884ddf520d321bcd822d1461330876...
mv: cannot move '/home/kazu/development/flutter/bin/cache/dart-sdk' to
'/home/kazu/development/flutter/bin/cache/dart-sdk.old': Permission denied

接下来，我试了sudo

sudo flutter upgrade

然后我得到了这个。

sudo: flutter: command not found

你能给我一些建议吗？

【问题讨论】：

【参考方案1】：

对我来说，您遇到的问题是当前用户在dart-sdk 文件夹中没有权限。您需要重新检查权限或dart-sdk文件夹。

示例运行ls -la查看详情

drwxr-xr-x 10 user-xxx staff 320 6 Jun 10:18 dart-sdk

如果不是当前用户，使用sudo chown 更改dart-sdk 文件夹的所有者。

再次尝试flutter upgrade。

更新解决方案：（参考：github.com/flutter/flutter/issues/17898）

手动将 dart-sdk 重命名为其他名称可以解决问题。或者在flutter升级之前运行这个命令git clean -xffd git pull flutter doctor

【讨论】：

非常感谢您的回答。我检查了ls -la，这就是结果。 ``` drwxr-xr-x 1 kazu kazu 4096 May 29 06:32 dart-sdk``` 当前用户是kazu，所以我还有一个问题。嗨@KazuakiSuzuki，我在这里找到了您遇到的问题：解决方案：手动将 dart-sdk 重命名为其他名称解决了问题。或者在flutter升级之前运行这个命令 git clean -xffd git pull flutter doctor [链接]github.com/flutter/flutter/issues/17898。我希望它有所帮助。非常感谢您的建议。您的解决方案完美运行。我试过git clean -xffd git pull flutter doctor before flutter upgrade 没有和我一起工作【参考方案2】：

当你试图调用一些flutter 命令并有这样的输出时：

Downloading Dart SDK from Flutter engine 40441def692f444660a11e20fac37af9050245ab...
mv: rename /Library/Flutter/bin/cache/dart-sdk
to /Library/Flutter/bin/cache/dart-sdk.old: Permission denied

这意味着您没有足够的权限或文件属于另一个用户。
