VS Code 命令托盘中的 Flutter 找不到 git

Posted 2023-02-23

【中文标题】VS Code 命令托盘中的 Flutter 找不到 git

【英文标题】：Flutter in VS Code command pallete doesn't find git

【发布时间】：2020-04-23 17:32:12

【问题描述】：

我一直在尝试在我的笔记本电脑上设置 Flutter，但没有成功。问题很可能出在 VS Code 中的扩展或某些东西上。我可以从 Powershell 运行颤振命令没问题。但是从 VS Code 命令面板执行的命令报告如下：

[flutter] flutter doctor -v
'where' is not recognized as an internal or external command,
operable program or batch file.
Error: Unable to find git in your PATH. 
exit code 1

这很奇怪，我的计算机设置中确实有 git 可以直接从 Powershell 工作 - 它在 PATH 中。此外，命令面板中可用的来自 VS Code 的 GIT 命令也可以正常工作。

我能够检查的每个日志都报告上述消息或仅报告“位置”部分。

请帮忙，如果您需要任何其他信息，我很乐意提供。谢谢你:)

编辑#1： Flutter Doctor 现在会产生崩溃。它以前工作过，但现在它报告错误。这是它生成的日志：

【参考方案1】：

我升级到flutter 1.19.0-3时遇到了同样的问题，我解决了。 此问题可能是由“路径变量”引起的，建议您确保您的路径包含以下所有路由。 'system32、Git bin、flutter bin 和 powershell'。如果您使用的是 Windows，这些路由通常如下所示，因此您可以将以下行复制到您的“路径变量”中。

C:\Windows\System32;
C:\Program Files\Git\bin
C:\flutter\bin;
%systemroot%\System32\WindowsPowerShell\v1.0\;
%SystemRoot%\system32;%SystemRoot%;

【讨论】：

是的，这就是我在解决方案中评论的内容。由于某种原因，我错过了第一行（在你的情况下）。有趣的是更新是如何搞砸的。

【参考方案2】：

在您的计算机上安装 git desktop 并重新启动您的 IDE。

【讨论】：

我已经按照你的要求做了。还是行不通。除了 VSCode Flutter 任务之外，我可以在任何其他终端上使用 git。

你检查环境变量中的git路径了吗？

是的，它就在那里。我也在 VSCode 中明确设置了 git.exe 的路径，但这并没有改变。 PATH 必须指向 Git 中的“bin”目录，对吗？

是的，你是对的。你可以使用 android studio 或 intelj 作为 IDE

我还没试过。我会在今天晚些时候回来报告。

【参考方案3】：

所以，我的 PATH 变量中缺少 C:\Windows\System32 值。我的 PATH 中有 Powershell，但没有 System32。要让 Flutter 工作，你需要两者。

我对任何有类似错误的人的建议是，检查 PATH 变量的默认值并将它们设置回去 :)
