[英]npm install fails (unable to resolve dependency tree)
Trying to reduce any changing variables and using a fresh pull of my code.试图减少任何变化的变量并使用我的代码的新拉动。 They are no node-module
packages or package-lock.json
.它们不是node-module
包或package-lock.json
。 I run npm install
I get this error:我运行npm install
我得到这个错误:
npm ERR! code ERESOLVE
npm ERR! ERESOLVE unable to resolve dependency tree

If I do an install via --force
or npm install --legacy-peer-deps
I get a bunch of files mark as outdated and when I run npm update
I get the same error.如果我通过--force
或npm install --legacy-peer-deps
我会得到一堆文件标记为过时,当我运行npm update
时,我会得到同样的错误。 I have tried clearning the cache of my npm as well with no luck npm cache clean
.我也尝试清除 npm 的缓存,但没有运气npm cache clean
。 I don't know why this is happening as there is no node-module folder or anything installed for it to give error under my node_modules/react-native-screens
...they are no node_modules folder yet.我不知道为什么会发生这种情况,因为在我的node_modules/react-native-screens
下没有节点模块文件夹或任何安装的东西会给出错误...它们还没有 node_modules 文件夹。 What is causing this and how can I fix it?是什么原因造成的,我该如何解决?
Edit: I ran npm update -g
, then npm audit fix
and then I got an error:编辑:我运行npm update -g
,然后npm audit fix
,然后出现错误:
code ERESOLVE
ERESOLVE unable to resolve dependency tree
While resolving: Sculp latest app@undefined
Found: react-native-screens@2.15.2
node_modules/react-native-screens
react-native-screens@“~2.15.0” from the root project
so I ran expo install react-native-screens
and saw that it couldn't find expo...checked my folder and my node_module
folder is missing.所以我跑了expo install react-native-screens
并看到它找不到 expo ...检查了我的文件夹并且我的node_module
文件夹丢失了。 Like if it never was there or gotten installed.就像它从未存在或安装过一样。
edit: I have tried all the methods listed below and it gives random errors that I can not fix it undefined is not an object (evaluating '_core.ThemeColors.light')
and I have googled this and one of the main solutions is delete npm and package-lock.json and reinstall but that brings me back to where I started.编辑:我已经尝试了下面列出的所有方法,它给出了我无法修复的随机错误undefined is not an object (evaluating '_core.ThemeColors.light')
,我已经用谷歌搜索了这个,主要解决方案之一是删除 npm和 package-lock.json 并重新安装,但这让我回到了开始的地方。
It works for me:这个对我有用:
npm install --save --legacy-peer-deps
Try to copy your src folder and package.json file and initialize another react-native (new) and replace the source the src folder and package.json file and reenter npm install. Try to copy your src folder and package.json file and initialize another react-native (new) and replace the source the src folder and package.json file and reenter npm install.
You can use --force in the command line, but you will problably have to deal with a broken react-native dependency later.您可以在命令行中使用 --force,但稍后您可能必须处理损坏的 react-native 依赖项。 Anyway, there are other ways of dealing with this broken dependency.无论如何,还有其他方法可以处理这种损坏的依赖关系。
Try this:尝试这个:
npm config set legacy-peer-deps true npm 配置设置 legacy-peer-deps true
Note: this will set this flag permanently注意:这将永久设置此标志
For one time:一次:
npm install --save --legacy-peer-deps npm install --save --legacy-peer-deps
Try it in the following:在以下情况下尝试:
npm add react-native
expo install (your needed module)
