这周假期刚过，回到工位的我一打开 VSCode，奇怪的发现 VSCode 终端多出了一行警告信息：

‘chcp’ is not recognized as an internal or external command, operable program or batch file

看到这个警告信息我感觉不对啊，用了近三年的 VSCode 了，终端从来没有弹出过这个警告，怎么会连chcp都识别不了呢？然后我又试了试 conda、java 甚至是 cmd，结果它居然什么命令都识别不了了。退出 VSCode，直接打开 cmd，又一切正常了，该有的命令一个都不少？？？

初步猜测是 VSCode 的 bug？我更新到最新版（当时是 1.97.2），然后打开终端依旧错误 👿。我又怀疑是不是我修改 settings 导致的，在选择同步以前的设置时候还发现 1.97.2 版本的 VSCode 登录微软账户会异常，这下可好，不仅没有解决原来的 bug，还发现 VSCode 的新 bug😠。

发现问题

换成之前版本的 VSCode 并且成功同步到之前的设置之后，这个 bug 依然没有解决。我又在想，是不是安装了什么插件导致了这个错误呢？于是我在 VSCode 中选择 禁用所有已安装的扩展，然后终于终于，这个 bug 没有再出现了，那么就能确定确实是 VSCode 的插件出了问题。经过反复尝试，我发现是“Python”这个插件出的问题，只要装这个插件的最新版，命令行就会失效…

可是这个插件是必备插件，我换成 2023.2 版本的"Python"虽然规避掉了这个 bug，但是也导致一些功能没法正常使用，而且我询问了其他朋友，他们的电脑上装最新版本的"Python"都是正常的，为啥我的偏偏就不行？仔细想了想，VSCode 的 cmd 终端不能执行任何命令，就说明 VSCode 的 cmd 终端遗忘了系统配置的 PATH 变量，这个 bug 很可能是 Python 插件在终端输入了未知命令导致的。

查看 Python 插件的日志

因此，顺着这个思路，我在使用 VSCode 启动项目的时候查看了一下 Python 插件的日志，信息如下：

从这两份日志信息中可以看出，Python 插件会自动调用 conda 环境，并且加载插件中的脚本，但是我自己这部分日志出错比较迷的地方就是[warning] could not find a pixi interpreter for the interpreter at python，这个 pixi 我根本没有使用过，我甚至都不知道它是什么。

简单搜索之后，了解到它是和 Anaconda 差不多的，管理 Python 环境的应用，可是这关我的 cmd 什么事？而且我压根儿就没安装过这个pixi啊，Python 插件为什么要调用它？？🤨

Github 上的解决方案

在 Google 搜索了一下这个 issue，发现确实有很多人遇到这个错误：

方案 1

直接安装 pixi，这位用户在安装好 pixi 之后解决了问题。不过我身边不安装 pixi 也能正常使用 Python 插件的例子比比皆是，这个方案我不想采纳。

方案 2

在 settings.json 中增加下面的配置，有些用户使用该命令解决了问题，但我尝试了无效。而且从刚才的日志信息中也可以看出，Python 插件启动的时候就会检验 pythonTestAdapter 状态。

方案 3

在 settings 中增加下面的配置，禁止 Python 插件激活 VSCode 的终端，这个我尝试过了，确实是有效果。这样虽然避免了启动 VSCode 的时候终端报错，但是也会导致启动 Python 程序的时候容易出错。还有就是每次新开启一个终端，都得手动激活 conda 环境，这个实在让我无法接受，因为之前我一直是没有出现这个问题的，所以我觉得这也不是治疗根本的解决方案。

1
"python.terminal.activateEnvironment": false

我的解决方案

上面的方案都没有解决我的问题，那么最后的方案还是只有再仔细的检查一下 Python 插件的日志了。还是回到刚才的结论，主要原因还是 Python 插件在启动时导致 终端没有正常加载系统变量 Path，最后才导致 VSCode 内部的 cmd 什么命令都识别不了。我检查了一下自己的环境变量，发现里面确实有很多重复的路径以及失效路径，于是我使用大模型对其进行去重，然后删除了几个不需要的系统路径，然后重启电脑，再次启动 VSCode，这次终于正常了！！

猜测原因：

  1. 很可能是因为原本的 Path 中有很多重复的路径，导致 Path 的长度超长，所以 cmd 命令加载失败；
  2. 还有可能是 Path 变量内部的写法不符合标准，之前我担心 Path 变量太长，使用%Path01%变量代替一部分路劲，在这篇博客 https://www.cnblogs.com/yunying61/articles/16810383.html 中提到了注意事项：
