I have successfully connecting 2 machine with Hyperledger composer. Somehow in the middle, the couched crashed. So somehow I want to restart my Hyperledger from the start.
When I tried to create admin card, No version of composer-cli has been detected, you need to install composer-cli at v0.19 or higher
So I did a little bit search at stack overflow and found some good information. Then I tried to uninstall composer-cli and reinstall it.
when I tried to uninstall it, ENOENT: no such file or directory, open '/home/ptech_root/package.json'.
I don't know why this happens.
when I tried to install npm install -g composer-cli#0.20, I get this.
/home/ptech_root/.nvm/versions/node/v8.15.0/bin/composer -> /home/ptech_root/.nvm/versions/node/v8.15.0/lib/node_modules/composer-cli/cli.js

updated 1 package in 9.083s
but seems like I cannot uninstall it.
any idea why?
I think it is because of the PATH. But I don't know what should I do with this. I am fairly new in this field.
Found the problem
I was using ubuntu at azure VM, I need to use sh ./createPeerAdminCard.sh instead of ./createPeerAdminCard.sh. I am not sure why this works. In my amazon VM I don't need to put this SH, so if anyone know why this sh thing is works at azure, but not at amazon, please share why.

I found an error in sharp.
After that, I found a blog in which they ask to delete sharp from the node module and run sudo npm i.
I have gone through GitHub and write minipass - 2.7.0
After that, I got a new error in
vips/vips8 file not found #include <vips/vips8>
I'm using Ionic with Angular on Macbook
I use commands which is
1.sudo npm install
2.sudo npm i gulp-sass -ES --unsafe-perm=true
3.sudo ionic cordova platform add ios
I very recently ran into a similar issue after making some changes to a project's package.json on my Mac (not an Angular or Cordova project).
I came across this GitHub issue for the sharp package which mentioned you may need to update the globally-installed version of libvips: https://github.com/lovell/sharp/issues/1148
In my case, since I use Homebrew but had not directly installed this package previously, I was able to resolve by running brew install vips and then re-running npm install. Note that it has a lot of dependencies so installation may take some time.
Edit: if that doesn't work, you may need to try a fresh install by removing node_modules, then re-running npm i.
This might be not applicable to everyone, but remove package-lock.json and node_modules directory first and then try npm install again. (I also added the minipass in my package.json, by the way)
In my case, I had encountered the same error, but I could solve it by doing the above.
First of all, below is required information.
OS: macOS Mojave 10.14.2
Node: 10.13.0
AndroidStudio: 3.1.4
When I run appium doctor, I'am getting two optional dependencies are missing.
1. `opencv4nodejs`
2. `bundletool.jar`
If I try to install opencv4nodejs, but I got warning:
opencv4nodejs#4.14.0 has no binaries
(It seems like auto build failed)
And I have no idea how to add export bundletool.jar as PATH.
I just ran into this myself. Installing opencv4nodejs was pretty easy - for that, I used:
npm -g install opencv4nodejs
There may have been dependencies of 'opencv4nodejs' that I had to install - I can't remember; that may have required me to install 'make' with brew install make
The hard one was the bundletool.jar - here are the steps I followed for that:
Searched for 'bundletool.jar' and found a place to download it from Google - I got 'bundletool-all-0.8.0.jar' from https://github.com/google/bundletool/releases
I renamed this file to just 'bundletool.jar' and placed in my Android SDK folder, under its own sub-folder called 'bundle-tool' - full path: /Users/{USER}/Library/Developer/Android/sdk/bundle-tool
I had to make the bundletool.jar executable with:
chmod +x bundletool.jar
Added the 'bundle-tool' folder to Path with the following addition in my ~/.bashrc file:
PATH="$PATH:$ANDROID_HOME/bundle-tool"
Now running which 'bundletool.jar' is happy and finds it in the 'bundle-tool' folder I created (see step 2)
Running 'appium-doctor' is now satisfied - and doesn't report any missing dependencies.
Hope that helps.
2019-10-31 update:
With MacOS Catalina (specifically 10.15.1) - I ran into a problem with installing opencv4nodejs using the npm command shown above. Opencv4nodejs wants to be built - but using C++ 11 features (from what I read) and has a problem with constexpr on MacOS. So, I first installed OpenCV with Brew - using brew install opencv#4 and then had to set the environment variable to not autobuild OpenCV with export OPENCV4NODEJS_DISABLE_AUTOBUILD=1
Then I was able to install opencv4nodejs with the npm command shown above - and appium-doctor shows that its dependencies are in place.
I have a problem after I upgraded my machine to Yosemite, whenever I run sudo npm install -g ... I got an error says
/usr/bin/dyld: DYLD_ environment variables being ignored because main executable (/usr/bin/sudo) is setuid or setgid
For example was trying to install gulp using
sudo npm install -g gulp
and got the same error ! not able to find the reason behind this issue
Generally this means that an existing, globally installed package is in bad shape. Possibly permissions related, but hard to say for sure without more information about the environment.
The solution lies in fixing the broken package. One way to do so is delete and re-install it. Try sudo npm uninstall -g <pkg> where <pkg> is anything you suspect may be broken.
If you are not sure where to start, do:
npm list -g --depth=0
That will show you all of your globally installed packages. Just remove and re-install them one by one.
If any of those throw errors during the removal process, you will need to do it yourself, manually.
First, figure out where global packages are installed. Generally, this will be /usr/local on OS X, for example. To find out for sure:
npm config get prefix
Then explore that directory, especially /usr/local/bin (for example) and if you are sure a file is related to a global npm package, it's usually safe to remove it.
`sudo rm -rf <file>`
... where <file> is the actual filename you wish to delete.
You may have gotten into this mess due to overuse of sudo.
See my answer to SNAFU with npm update -g on why sudo is bad and instructions on how to fix it.
I'm trying to install Cordova and Ionic Framework on a Ubuntu server. I already used Node.js on it, so simply ran:
sudo npm install -g cordova
Then I cloned a sample project from GitHub
sudo git clone https://github.com/driftyco/ionic-weather.git
I entered the directory and tried to add the iOS platform library in order to build it:
cd ionic-weather
sudo cordova platform add ios
However it throws the following error:
Creating ios project...
/home/benedict/.cordova/lib/ios/cordova/3.4.0/bin/create: 33: /home/benedict/.cordova/lib/ios/cordova/3.4.0/bin/create: Syntax error: "(" unexpected

at Process.ChildProcess._handle.onexit (child_process.js:810:5)
I've tried reinstalling Cordova in case something got corrupted, but no luck. I can't seem to find anyone else with this issue either so I'm kinda stuck. Any ideas?
This turned out to be a combination of several problems:
Ant is a required dependency, although it's not documented as a dependency as far as I can tell from any of the install guides the ionic guide or cordova guide point to. In fact I found this out by digging around SO and a few other dark corners of the internet
JDK must also be installed. (not just JRE)
2 folders have to be added to the path (for Android anyways).
Ant
This can be installed via sudo apt-get install ant.
jdk
sudo update-alternatives --config java
first, you can find out if you have jdk by running `sudo update-alternatives --get-selections | grep ^java
if you already have the jdk, you can update your jre to the jdk version using sudo update-alternatives --config java
if not, then install jdk (not just the jre), using sudo apt-get install openjdk-7-jdk
Path setting in ~/.bashrc
$ cd ~
$ sudo vi .bashrc
at the bottom, before the PATH= add the path to the bundle folders for both platform-tools folder and the tools folder under the sdk folder. Several of the guides only mention the platform-tools folder.
The guide specifically mentions ios can't be installed on Windows, but strangely leaves out Linux. This may be an oversight, but I can't be sure. There was some indication in the ionic guides that ios emulation could be done on linux, even though actual development could only be done on OSx.
the ios platform requires xcode 4.5 with cordova, which needs OSx 10.7 you basically can't add the ios platform tools on Windows or Linux. Unfortunately cordova and ionic both seem to forget Linux exists, and therefore the docs imply this will run on Linux when they note inoperability on Windows but say nothing about Linux.
Your problem is that your trying to build the app on a machine that doesnt have Mac OS installed. In order to add IOS platform you need to run this command on a mac.

So I've been using homebrew to install various packages/libraries/programs on my mac. I keep running into a problem in which homebrew tells me that I have unlinked kegs in my Cellar.
For instance, upon running brew install phantomjs I received the following message:
Warning: Could not link phantomjs. Unlinking...
Error: The `brew link` step did not complete successfully
The formula built, but is not symlinked into /usr/local
You can try again using `brew link phantomjs'
Possible conflicting files are:
/usr/local/bin/phantomjs -> /usr/local/lib/node_modules/phantomjs/bin/phantomjs
I tried running brew link phantomjs as recommended, and hit a similar problem:
Error: Could not symlink file: /usr/local/Cellar/phantomjs/1.9.2/bin/phantomjs
Target /usr/local/bin/phantomjs already exists. You may need to delete it.
To force the link and overwrite all other conflicting files, do:
brew link --overwrite formula_name
The command brew link --overwrite --dry-run phantomjs gives the following message:
Would remove:
/usr/local/bin/phantomjs -> /usr/local/lib/node_modules/phantomjs/bin/phantomjs
I will probably go ahead and overwrite, but this appears to happen every time I try to install something with homebrew. Why? Why isn't homebrew working as expected?
Thanks.
From what I can tell, looks like you have previously done:
% sudo npm install -g phantomjs
In this case, you should do the following:
% sudo npm uninstall -g phantomjs
% brew link --overwrite phantomjs
I thought I'd take a crack at this. I ran into a similar problem today, and I think it may be related to this:
https://github.com/Homebrew/homebrew/issues/22408
Long story short, I think it has to do with how npm manages packages vs how brew does it. (I'm assuming you installed node with its defaults, which would have given you npm).
At some point you probably installed some package with npm. Maybe grunt, karma, etc..those by default end up in /usr/local/lib/node_modules.
Maybe one of those packages or its dependencies(or sub-dependencies) depended on phantomjs (I think Karma might use phantomjs?) Anyways, if now you are trying to brew install phantomjs, which is trying to make a symlink to it, that may be conflicting with the already existing symlink that npm created for you..
I think you can change the symlink path for that package so that brew permanently points to that already installed package in the node_modules folder. Sorry not to be more specific, I'm just figuring this out myself.
