Problems encountered in the process of creating and mac flutter environmental solutions

1. Open the terminal

2.clone flutter

command:

git clone -b beta https://github.com/flutter/flutter.git

Step this given terminal:

error: RPC failed; curl 18 transfer closed with outstanding read data remaining

fatal: The remote end hung up unexpectedly

fatal: early EOF

fatal: index-pack failed

Solution look at this one: git clone error: error: RPC failed; curl 18 transfer closed with outstanding read data remaining solution

3. Open (or create) .bash_profile

1. Open

Input Terminal:

open -e .bash_profile

If you can not successfully opened, it created

2. Create

1. Enter the current user's home directory (the default is)

cd ~

or

cd /Users/用户名

4. Update the environment variables

Open bash_profile is to be permanently updated environment variables, once and for all. See the explanation and attention to their own needs to add code to the open bash_profile.

export PUB_HOSTED_URL=https://pub.flutter-io.cn
export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn

Explanation: Since some fluttercommands need to get data networking, if you are in-country visit, due to reasons known, direct access to it may not be successful. The above PUB_HOSTED_URLand FLUTTER_STORAGE_BASE_URLis google for domestic developers to build temporary image. You can not set up, if you can, then over the wall. If not, then you can directly copy the code above

export PATH= PATH_TO_FLUTTER_GIT_DIRECTORY/flutter/bin:$PATH

Note : PATH_TO_FLUTTER_GIT_DIRECTORYthe path you flutter, as in the current path in user. If you are unsure, you can click mac menu above the "Go" -> "Personal", then this folder to find whether there flutter folder. If any of you should write:

export PATH= /Users/用户名/flutter/bin:$PATH

Then enter the following command to update the environment variables you just configured:

source .bash_profile

Then enter the following command, by running the flutter/bincommand to verify whether the directory has been in the PATH:

echo $PATH

If you see that there is a good distribution flutter

5. Run flutter doctor

Enter the following command to install point of view there are no dependencies:

flutter doctor

I say this is a start

Tip flutter version is too low

Let me update flutter, so I do not want to see the warning immediately updated.

flutter upgrade

Error 1:

And then look at x, and this is my first crossed a place

[✗] Android toolchain - develop for Android devices
    ✗ Unable to locate Android SDK.
      Install Android Studio from: https://developer.android.com/studio/index.html
      On first launch it will assist you in installing the Android SDK components.
      (or visit https://flutter.io/setup/#android-setup for detailed instructions).
      If Android SDK has been installed to a custom location, set $ANDROID_HOME to that location.

Way, I am installing android studio and set the environment variable $ ANDROID_HOME.

I then follow the prompts to open https://developer.android.com/studio/index.html , and download and install android studio.

After installation run the best android studio, good installation andriod sdk. According to the interface for operation next point, if there is no sdk will be prompted to install, as long as the point on the line. Remember to view the installation path, the path is usually in the current user's Library folder.

After installing the sdk, android studio can be put off.

Then open bash_profile

open -e .bash_profile

In bash_profile years plus

export ANDROID_HOME="/Users/用户名/Library/Android/sdk" //android sdk目录，替换为你自己的
export PATH=${PATH}:${ANDROID_HOME}/tools
export PATH=${PATH}:${ANDROID_HOME}/platform-tools

Update Configuration

source .bash_profile

Then run

flutter doctor

See also this one is not an error. ok there are still error, given as follows:

Then follow the prompts have been y, y to the end.

Error 2:

This is my second place crossed

Unable to install on mac * libimobiledevice *, throws the following exception:

checking for openssl >= 0.9.8... no
configure: error: OpenSSL support explicitly requested but OpenSSL could not be found

READ THIS: https://docs.brew.sh/Troubleshooting

Tried many gestures will not work, I finally found a way:

brew install gnutls
brew install libgcrypt
./autogen.sh --disable-openssl
make
make install

And then:

brew install ideviceinstaller

And then:

brew install ios-deploy

Then also:

brew install cocoapods

Finally, then:

pod setup

I carried it to the error:

[!] /usr/bin/git clone https://github.com/CocoaPods/Specs.git master --progress

Get hold of accelerators on it. I use the cloud wall netfits, there is a trial, a trial download enough. If there is a better accelerator welcome message.

Then run doctor

flutter doctor

ios also given:

[!] iOS toolchain - develop for iOS devices (Xcode 9.4.1)
    ✗ Missing Xcode dependency: Python module "six".
      Install via 'pip install six' or 'sudo easy_install six'.

Prompted to enter 'pip install six' or 'sudo easy_install six'. And then run the doctor, I am not being given the ios here. 3 got left error in the error.

When the execution brew install --HEAD libimobiledevicetime will encounter a problem:

brew install --HEAD libimobiledevice

==> Cloning [https://git.libimobiledevice.org/libimobiledevice.git](https://git.libimobiledevice.org/libimobiledevice.git) Updating /Users/rjoiner/Library/Caches/Homebrew/libimobiledevice--git

Requested 'libusbmuxd >= 1.1.0' but version of libusbmuxd is 1.0.10

Simply black question mark ah, so a lot of information output. But take a closer look at the last line, we will find anomalies where Requested 'libusbmuxd >= 1.1.0' but version of libusbmuxd is 1.0.10, apparently due to inconsistencies * libusbmuxd * version and the version you want to install the system requirements.
After some searching finally found the problem:

A recent change to libimobiledevice bumped the constraint on libusbmuxd to >= version 1.1.0. The current usbmuxd homebrew package is version 1.0.10.
As a result, homebrew --HEAD installs of libimobiledevice no longer build without a --HEAD install of usbmuxd.
Until the usbmuxd homebrew formula is updated, a workaround is to install it at HEAD:

总之就是libimobiledevice更新了，我们可以通过下面的方式安装libimobiledevice:

brew update
brew uninstall --ignore-dependencies libimobiledevice
brew uninstall --ignore-dependencies usbmuxd
brew install --HEAD usbmuxd
brew unlink usbmuxd
brew link usbmuxd
brew install --HEAD libimobiledevice
