Expo commands throwing “Error: Cannot find module 'minizlib'”

问题

Whenever I try to run such commands as expo init or expo start or even just expo, it responds with:

Error: Cannot find module 'minizlib'

I have tried install and reinstalling minizlib, along with expo, expo-cli, npm, and node and nothing has worked. Any help would be appreciated.

OS: Ubuntu 18.04.2

I had the same issue. I downgraded to version 10 of node using nvm install 10 (If you do not have NVM look into it here it is very useful) then reinstalled the expo-cli with npm install -g expo-cli. This ended up solving the issue for me.

Note: This downgrade is temporary if you want to make it your default version you have to run nvm alias default 10

I had the same issue with "minizlib" not being found. None of the solutions posted on here or other threads regarding this issue solved it.

But, I figured it out. And here is what worked for me. Its pretty straight forward.

• All the modules necessary for Expo to run should be located at /usr/local/lib/node_modules/expo-cli/node_modules/
• So, go to your home directory and run npm install minizlib@2.1.0. This will put the module file in the home directory. (I say home directory so that the npm install doesnt clutter files into whichever directory you were previously working on)
• Now, you need to copy+paste the module folder to whichever folder npm is looking for while running the expo command. In your case its /usr/local/lib/node_modules/expo-cli/node_modules/

This solved the problem for me. If it worked for anyone else, please validate it for me.

install the library

npm install -g minizlib

I had the same issue and I found the way to solve it in an external forum. thanks to @parkerroanm answer there.

Anyway, here is how I solved it (from the answer I found):

1. I uninstalled expo-cli with this command: sudo npm uninstall -g expo-cli This is did not actually uninstall expo and nothing I could do would. So i deleted the folder with this command: sudo rm -r /usr/local/lib/node_modules/expo-cli
2. Then reinstalled using yarn instead with: yarn global add expo-cli --save
3. I updated the PATH in .bashrc to include export PATH="$(yarn global bin):$PATH" to the bottom of the file.

This fixed the issue for me.

It seems to all stem from a permissions error on installation for the sharp library.
