jupyter lab build 失败

shadow150519 commented 3 years ago

请问一下，我也遇到了和你博客上一样的问题，搞了一晚上了都没搞定，如何在Windows上解决这个问题呢?

不是很清楚你说的一样的问题具体到哪一步, RuntimeError: npm dependencies failed to install 还是后边日志里找到npm源出错了. 可以仔细看下日志

以下是我的日志, 我感觉我的问题应该和你的是一样的.但是我在Windows上找不到对应node_modules文件夹和yarn.lock.我在jupyterlab提过这个issue,然后他们官方的回答是,因为jupyter-lab 3.X.X,有了prebuild 版本的插件,可以直接使用pip和conda安装,不需要node和npm了.但是我对着他们官网上的的实例操作有没效果.所以可以麻烦大佬帮我康康应该怎么解决吗?

这个报错不出意外和我的一样是yarn的源出了问题, 首先找到jupyter lab内置的yarn位置, 应该是在D:\deepin\Anaconda\share\jupyter\lab\staging\下

试试(很少写cmd命令了, 可能有错):

cd D:\deepin\Anaconda\share\jupyter\lab\staging
rmdir /s/q node_modules
del yarn.lock
node yarn.js config list  %查看yarn配置, 尤其是registry的值%
node yarn.js config set disturl https://registry.yarnpkg.com
node yarn.js config set registry https://registry.yarnpkg.com
node yarn.js install

如果node没有在环境变量的话(提示node命令不存在), 自行寻找内置node的可执行文件下在哪儿了, 我这边没法帮你. 或者自行安装node.
