Question

我已经在Windows 10上安装了Linux子系统（WSL）和Ubuntu 16.04，然后按照this安装yarn：

sudo apt update
sudo apt install curl
curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add -
echo "deb https://dl.yarnpkg.com/debian/ stable main" | sudo tee /etc/apt/sources.list.d/yarn.list
sudo apt update
sudo apt install yarn

它没有引发任何错误。但是，yarn --version返回了

$ yarn --version
/mnt/c/Users/chengtie/AppData/Roaming/npm/yarn: 12: /mnt/c/Users/chengtie/AppData/Roaming/npm/yarn: node: not found

npm --version返回了

$ npm --version
: not foundram Files/nodejs/npm: 3: /mnt/c/Program Files/nodejs/npm:
: not foundram Files/nodejs/npm: 5: /mnt/c/Program Files/nodejs/npm:
/mnt/c/Program Files/nodejs/npm: 6: /mnt/c/Program Files/nodejs/npm: Syntax error: word unexpected (expecting "in")

有人知道如何解决此问题吗？

您必须先安装nodejs

#:kivy 1.11.1

ScreenManager:
    MainScreen:
    GameScreen:

<MainScreen>:
    FloatLayout:
        MDRectangleFlatButton:
            text: "Start!"
            on_touch_down: root.manager.current = "game"
            pos_hint: {"center_x" : 0.5, "center_y" : 0.5}
            size_hint: None, None
            size: 300, 100

<GameScreen>
    on_enter: self.play()

<PingPongBall>:
    size: 75, 75
    canvas:
        Ellipse:
            pos: self.pos
            size: self.size          

<PingPongPaddle>:
    size: 50, 300
    canvas:
        Rectangle:
            pos:self.pos
            size:self.size

<PingPongGame>:

    ball: PingPong_ball
    player1: player_left
    player2: player_right

    canvas:
        Rectangle:
            pos: self.center_x - 5, 0
            size: 20, self.height

    Label:
        font_size: 140  
        center_x: root.width / 4
        top: root.top - 50
        text: str(root.player1.score)

    Label:
        font_size: 140 
        center_x: root.width * 3 / 4
        top: root.top - 50
        text: str(root.player2.score)

    Label:
        font_size: 35
        center_x: root.width * 6/7
        top: root.top - 650
        text: "by me"

    PingPongBall:
        id: PingPong_ball
        center: self.parent.center

    PingPongPaddle:
        id: player_left
        x: root.x
        center_y: root.center_y

    PingPongPaddle:
        id: player_right
        x: root.width - self.width
        center_y: root.center_y

看看这个：

/mnt/c/Users/chengtie/AppData/Roaming/npm/yarn: 12

它正在寻找Windows上安装的纱线。您必须从Windows卸载纱线，或将其从WSL的PATH中删除。

使用以下命令从PATH中删除Windows纱线：

WIN_YARN_PATH="\$(dirname "\$(which yarn)")"
export PATH=\$(echo "\${PATH}" | sed -e "s#\${WIN_YARN_PATH}##")

您可以将其添加到您的.bashrc

另外，请查看您的错误消息，它也从Windows获取npm，您需要使用相同的技术将其从路径中删除。
