自定义 jupyter labextension 安装失败

Question

我们有一个自定义的 jupyterlab 扩展无法安装 nodejs=14.14.0（和 15.2.1）（使用 conda 安装）。

以下是 package.json 文件的 labextension 的样子：

{
    "name": "my-custom-ext",
    "version": "0.1.0",
    "description": "Integrate JupyterLab with ext",
    "keywords": [
        "jupyter",
        "jupyterlab",
        "jupyterlab-extension"
    ],
    "homepage": "https://github.com/my_name/myextension",
    "bugs": {
        "url": "https://github.com/my_name/myextension/issues"
    },
    "license": "BSD-3-Clause",
    "author": "xyz",
    "files": [
        "lib/**/*.{d.ts,eot,gif,html,jpg,js,js.map,json,png,svg,woff2,ttf}",
        "style/**/*.{css,eot,gif,html,jpg,json,png,svg,woff2,ttf}"
    ],
    "main": "lib/index.js",
    "types": "lib/index.d.ts",
    "repository": {
        "type": "git",
        "url": "https://github.com/my_name/myextension.git"
    },
    "scripts": {
        "build": "tsc",
        "clean": "rimraf lib",
        "prepare": "npm run clean && npm run build",
        "watch": "tsc -w"
    },
    "dependencies": {
        "@jupyterlab/application": "^3.0.6",
        "@jupyterlab/apputils": "^3.0.5",
        "@jupyterlab/coreutils": "^5.0.3",
        "@jupyterlab/docregistry": "^3.0.6",
        "@jupyterlab/launcher": "^3.0.5",
        "@jupyterlab/mainmenu": "^3.0.5",
        "@jupyterlab/notebook": "^3.0.6",
        "@jupyterlab/services": "^6.0.5",
        "@lumino/commands": "^1.12.0",
        "@lumino/coreutils": "^1.5.3",
        "@lumino/disposable": "^1.4.3",
        "@lumino/widgets": "^1.16.1"
   
    },
    "devDependencies": {
        "@jupyterlab/builder": "^3.0.0",
        "rimraf": "^3.0.2",
        "typescript": "~4.1.3"
    },
    "jupyterlab": {
        "extension": true
    }
}

这是错误 jupyter labextension install --no-build my-custom-ext :

运行 “npm ls” 我得到了：

├─┬ @jupyterlab/builder@3.2.5
│ ├─┬ terser-webpack-plugin@4.2.3
│ │ ├─┬ cacache@15.3.0
│ │ │ ├─┬ @npmcli/fs@1.1.0

已将 package.json 更改为：

"devDependencies": {
        "@jupyterlab/builder": "=3.2.4",......

但这并没有帮助。仍然有同样的错误

注意：https://www.npmjs.com/package/@npmcli/fs：1.1.0 已于 5 天前发布。

请帮忙解决

此片段相关：

Expected version "^12.13.0 || ^14.15.0 || >=16". Got "14.14.0"

它告诉您需要使用节点 14.15.0 或更新的节点 14.x，并且您不能使用 13.x、15.x。但是你有 14.14.0 - 这意味着你需要升级你的 node.js.

您提到了 conda - 可能是您使用了过时的默认频道，因此您获得了 14.x 的旧次要版本； conda-forge 频道有所有版本，我建议切换到它。如果您已经使用 conda-forge 并且无法获得更新的版本，您可能想尝试使用 mamba 因为它有更好的依赖解析器。

注意：JupyterLab 3.x 目前还没有很好地支持 15.x 和更新版本（除其他外，因为并非所有依赖项都升级到 16.x，因为节点遵循奇偶版本节奏，其中只有偶数的数量足够稳定，足以让更广泛的生态系统有迁移的动力。
