当我在 wsl2 ubuntu 中启动 npm install 时出错

Question

当我运行 npm install 时，这个错误总是发生在我的项目中。那时，我从未在任何机器上发现此错误。但是，这是我第一次尝试 WSL2 Ubuntu。这是错误。

我不知道会发生什么，我认为我在 WSL2 中的开发环境非常完美。但可怜的我，我错了。请帮我。有没有人也遇到这个错误并且已经找到了解决方案？

Answer 1

阅读日志。这是一个node-gyp 错误，它会在安装时构建 NPM 包。在 Linux 上，它需要 GCC 和 Python (2)。 您需要安装 Python。如果您已经这样做了，请检查它是否是 Python 2。
对于这里的 Windows 用户，它还需要 Visual Studio (MVSC) 和 Python。
请参阅他们的 GitHub 存储库中的设置指南：

• Unix
• macOS
• Windows

Answer 2

我在 wsl2 ubuntu 20.04 上遇到了类似的问题。
Can't find Python executable "python", you can set the PYTHON env variable.

当我在终端中运行yarn install 命令时
它连接到wsl2 ubuntu，

1. 我遇到了互联网连接错误。 我解决了如下：
   sudo nano /etc/resolv.conf
   并将 nameserver 改为 8.8.8.8
   （这可能是临时解决方案，需要在重新打开 ubuntu 后进行） p>

2. 然后解决python2问题如下：
   sudo apt install python2
