如何使用 WSL2 正确设置 IntelliJ

Question

我无法运行在 WSL2 下创建的项目。我收到此错误。有谁知道是什么原因造成的？

Answer 1

官方说明：错误或过时？

JetBrains 的官方说明（位于https://www.jetbrains.com/help/idea/how-to-use-wsl-development-environment-in-product.html#debugging_system_settings）用于配置 Windows 防火墙，分为两部分

（官方）第1步：允许来自WSL的流量（这是正确的）

上述链接中的第一步是添加新的入站规则以允许来自 WSL 的所有流量（以管理员身份通过 PowerShell）：

New-NetFirewallRule -DisplayName "WSL" -Direction Inbound  -InterfaceAlias "vEthernet (WSL)"  -Action Allow

此命令起作用并添加新规则。

（官方）第2步：解除对IDEA的入站流量的阻塞（这是错误的）

说明中的下一步是删除阻止 IntelliJ IDEA 流量的现有规则：

Get-NetFirewallRule | where DisplayName -ILike "idea*.exe" | Remove-NetFirewallRule

该命令不执行任何操作，因为过滤器部分where DisplayName -ILike "idea*.exe"不匹配任何内容。

该DisplayName属性大概对应于Name防火墙控制面板中的列：

所以你可以看到“idea*.exe”在那里不匹配。

如果我将搜索更改为：

Get-NetFirewallRule | where DisplayName -ILike "IntelliJ IDEA*"

然后我得到了 shell 输出中返回的所有四个规则：

PS C:\Windows\system32> Get-NetFirewallRule | where DisplayName -ILike "IntelliJ IDEA*"

第 2 步：删除 IDEA 的入站流量阻塞（右）

当我禁用这两个公共入站规则，并设置新添加的 WSL 入站规则时，IDEA可以在之前因连接错误而失败的地方正确运行 Java。

您可以通过以下方法之一实现对 IDEA 的这两个入站公共规则的相同禁用/删除：

选项 1：具有高级安全性的 Windows Defender 防火墙 > 入站规则

在如上图所示的视图中，右键单击规则，然后为公共配置文件中的每个入站规则选择“禁用规则”。

选项 2：通过 PowerShell 禁用

您可以使用以下命令通过 PowerShell（以管理员身份）禁用相同的两条规则：

Get-NetFirewallProfile -Name Public | Get-NetFirewallRule | where DisplayName -ILike "IntelliJ IDEA*" | Disable-NetFirewallRule

选项 3：通过 PowerShell 删除

您可以使用以下命令通过 PowerShell（以管理员身份）删除相同的两条规则：

Get-NetFirewallProfile -Name Public | Get-NetFirewallRule | where DisplayName -ILike "IntelliJ IDEA*" | Remove-NetFirewallRule

所有这三种方法都对我有用，并允许我启用所有 Windows 防火墙配置文件（域、专用、公共），并且 Java 现在可以在位于 WSL2 文件系统中的 WSL2 项目上的 IDEA 中正确运行。

更新：我必须从最新的 2021.2 版本回滚到 2021.1.3，因为最新版本将“失去”连接到 WSL2 文件系统的能力，直到 WSL 重新启动。

我安装了两个版本，但我必须编辑防火墙规则以允许流量传输到 2021.1.3 程序（奇怪的是，在防火墙中也命名为2021.2！），并将公共配置文件（只是私有）添加到允许规则中。
